  • Hyalluronic sea serum

    Maria A. January 30, 2019

    Love it. It’s like a face lift.

  • Great product

    Lisa F. January 30, 2019

    Smooths on and absorbs quickly, not heavy at all. Really like using under daily moisturizer.

  • This is wonderful

    Tracy R. January 21, 2019

    Not only does this work but its good for my skin as well. No chemicals with results, Thank you!

  • Sadly a Miss for Me

    Natali V. January 21, 2019

    For all of the amazing reviews I really don’t see this serum doing much for my skin after weeks of use. I’m a little drier in the winter months and thought this could help, but this feels like a waste which is very disappointing considering the price. I much prefer the Vitamin Sea Serum, which was more hydrating and brightening for me.

  • Best product ever !

    Savannah R. January 16, 2019

    Love it ! I have bought multiple times ! Cannot get enough. Wish the bottle size was bigger for the price though.

  • Cant go without

    Jacqueline S. January 10, 2019

    As we get age and our skin changes we are always looking for ways to keep up with it. Sometimes we allow prices to dictate our purchasing decisions, especially when all our products run out at the same time.
    As a victim of this, I have learned the hard way when it comes to running out of Osea’s Hyaluronic Serum…I will no longer go without it! I notice such a difference in my skin when I do not have this product. It becomes dull and lackluster. Less plump and hydrated.
    So if you’re like me and have to prioritize your products, put this at the top of your list!

  • Sea serum is amazing

    Kim R. January 09, 2019

    I love this product. It’s light and yet feels super hydrating. I’ve been acne prone lately and this has been really great for moisturizing my skin without causing irritation. Love it!

  • Third time purchase

    Elyse W. January 08, 2019

    I love this serum! It’s perfect for my combination skin, doesn’t break me out or make me more oily in my t zone and helps to hydrate the dry patches on my cheeks and calms down the redness in my skin. Please don’t ever stop making this product!!

  • Favorite New Product!

    Carrie B. January 03, 2019

    Within two weeks of using OSEA’s Hyaluronic Sea Serum I noticed my face looked more hydrated. I’ve never had a product work so fast!

  • SMOOTH & BEAUTIFUL

    Elliot June 18, 2019

    This is a great product, it is light & easily absorbed in to the skin! I LOVE the way it makes my skin so smooth & beautiful, especially when I combine it with my Advanced Protection Cream, they are the perfect pair..

  • Must have serum

    Cayley June 17, 2019

    I love this serum so much, it’s great to find such an amazing all natural product. I use day and night.

  • Once you start you won’t stop

    Kj May 30, 2019

    All I can say is amazing amazing AMAZING. I’ve never felt so refreshed and dewy from any other serum I’ve tried (which believe me, there’s been plenty trial and errors with other brands). Ever since the first time I laid a drop of this serum on my face, I haven’t been able to stop! Having acne prone skin, I’ve been super apprehensive with serums because sometimes it makes my face oilier and shinier and others strip away too much of the oils where it leaves my skin irritated even more. This serum has done wonders to my skin and I’ve never seen it more dewy and fresh with the right balance of moisture without looking oily. YOU MUST GET YOUR HANDS ON IT! It’s a little bit on the pricier side but I’d like to say it’s an investment worth investing in! You won’t regret this product!

  • A daily must use product

    Karen J. May 26, 2019

    This serum delivers a smooth and plumped finish to my skin. I use this daily and am happy to havr tried this great product. The glass bottle with convenient push top dropper is great as well.

  • Wonderful product

    Terri D. May 20, 2019

    The product is everything it claims to be and the best part is the wonderful customer service.

  • Beautiful product

    Evelyn May 10, 2019

    I was amazed of how this left my skin with only one use. I have already gotten 3 compliments of how nice my skin looked. I highly approve of the ingredients! It was so worth it! 🙂

  • Review

    Merle G. April 11, 2019

    Everything it is purported to be, it delivers and more Bravi, Ladies !!!

  • Great product, poor packaging

    Linda February 22, 2019

    Love the refreshing feel and light consistency of the serum. However, the cheap plastic pump paired with the glass pipette is an unfortunate design choice. Would only purchase again if the applicator is changed, an insufficient amount is dispensed with the current design of the pump, making the product cumbersome to use.

  • Nice

    Laura B. February 14, 2019

    Not oily. Absorbs quickly.

  • Love it

    Kait L. February 11, 2019

    I like everything about this product. Good for sensitive skin. Great under makeup. Love it.

  • Hyaluronic Sea Serum

    Lauren F. February 09, 2019

    Great product! Just started using it but can already see results. Skin looks brighter and healthier

  • I would buy this product

    Sandra R. February 06, 2019

    I would buy this product again. I love it

  • Gel-Like Consistency and Long-Lasting

    Katherine R. February 04, 2019

    I have very dry / dehydrated skin. This serum did very well in providing relief for the dehydration and skin irritation, although I wasn’t much of a fan of the gel-like texture which seems to just sit on the surface of my skin and leaves a film residue. It didn’t feel like it absorbed as well. However it has lasted 2 months so far, I think there’s 2 more weeks left in my bottle. One drop is enough to cover my face and neck. I’d say it’s a good value for its price!

  • Game Changer

    Gaby November 08, 2019

    I heard about Osea from the To Be Magnetic Lacey Philips Podcast, and these products are amazing! My skin has acne scars and is oily, and at the end of the day, my skin feels tired, puffy, and dirty from the NYC air pollution. Tried this product in a sample and am stunned–it was like my face was being sucked into it’s normal place. Even my boyfriend noticed and said to me, wow you look younger and brighter. Huge game changer.

  • Fabulous

    Ashley F. October 29, 2019

    Thanks to Lacy’s interview with Melissa on the Expanded podcast, I discovered this fantastic line. I love the story behind the product and the quality.

  • this ish is bananas!!! 10/10 love this product

    Whitney October 21, 2019

    I literally love this stuff… Usually I am hesitant to use all natural products because I feel like they do not do much for my skin, & I do not see noticeable results, but this serum, in my opinion, is the epitome of a great skin care product: all natural that shows visible improvements in my skin!! I could honestly see a difference after ONE night of using it! It leaves my skin looking hydrated & dewy yet tight & firm. Also, it gives my skin a noticeable glow & leaves people asking me what I use on my skin, to which I say ‘OSEA hyaluronic sea serum, its amazing!!’ This product is seriously out of this world good, and I don’t see myself not using it anytime in the future.

  • I love it!

    Tallou October 21, 2019

    I have never used serums before, but I love this one!My skin feels amazing after every use. I did a lot of research before deciding to purchase a serum because they can be very pricey. I am 100% satisfied with my purchase.

  • Wonderfully Simple

    Colleen October 18, 2019

    I love this product! I am in my forty’s overall skin ok until it’s not. My skin is sensitive to many products. I have tried all high end and everything in between. This is simple, easy and absorbs lovely into the skin. My skin looks younger, brighter and I wear no make up. I am a working professional and this routine is what I have been needing! Give it a try! Hope you enjoy as I do.

  • Wow!

    Hillary A. October 08, 2019

    This is a great product! I have tried tons of products having been married to a dermatologist for over 20 years. The woman who does my facial recommended OSEA products. I got the hyaluronic serum to add moisture. Within a few days I can see a real difference! My face feels moist, soft and ‘plumper’ ( am 66). People have commented that I look different, like I am feeling better. I think it is my skin. My makeup looks smoother and more luminous. I am super pleased and highly recommend this product. I love that OSEA are very clean as I really strive to use only non-toxic, clean products on my skin. We live in such a toxic soup. I am not adding to my body’s burden with chemicals in skin and body care products!

  • Worth it!

    Alex September 27, 2019

    One of my new faves to my skin care routine. Makes my skin glowing, more plump looking, smoothed out very fine lines. Goes on nicely. My husband even commented that my face looked like it was glowing. Def worth the price!

  • Youthful glow

    Anoni August 12, 2019

    This serum does exactly what the description says. I have noticed the lines disappear, and have refreshed and younger looking skin. I am even using less and less makeup. That says a lot!

  • LOVE!!

    Amber K. August 05, 2019

    I absolutely love this hyaluronic acid serum. Keeps my skin hydrated and it’s light weight! Little goes a long way too!! Would recommend to everyone!

  • Excellent

    Carrie July 23, 2019

    This serum works AMAZING. If you read the product information it works exactly like it says that it is a lightweight non-greasy moisture boosting serum smoothes wrinkles fine lines etc. I have VERY sensitive skin I have had no issues with any of their products so far.

  • Huge difference!

    Aly T. July 23, 2019

    I have spots of dryness and especially break out when my skin is dry. This helps to hydrate my skin so much! I use it after the Sea Vitamin Boost and can feel an instant difference in the moisture!

    My skin is so sensitive and gets dry and itchy when I get out of the shower or wash my face so I use it immediately. My skin has never felt better!

  • I like it

    Em July 21, 2019

    I’ve recently received this serum and have been using for two weeks. I like the results so far. From what I can see, my skin looks more hydrated and looks more even toned. I’ve bought expensive skincare and prescription skin care from my dermatologist but after awhile they seem to stop working for me. I like natural products and this switch is ageeeable for me. I’m excited to see the results after I’ve used the whole bottle.

  • Wonderful Product!

    Diana E. July 21, 2019

    I love this product! I have a noticed a big difference in my skin! This product plumps, hydrates, and smooths my skin! My skin just feels comfortable and great! Definitely recommend! I use this in conjunction with the Advanced Protection Cream. Love both products!

  • LIFE CHANGING

    Monika June 23, 2019

    I’m 28 and this product was the first anti-aging product I’ve ever used, wow, super late in the game. I was starting to feel like my skin was dull and looked very tired, old, puffy, haha. This totally fixed it and more! It hydrates my skin so well and plumps it! My skin tone is even now and just looks youthful and bright! LOVE. I’m planning on trying more anti-aging products but I will never live without this. It’s vegan, gluten free, cruelty free… and it works! More companies like this, please!

  • Magic in a bottle

    Galit March 12, 2020

    I’ve tried tons of serums from clean beauty lines and nothing compares to this product. It leaves my skin feeling super soft and hydrated and has noticeably reduced the excess oil on my skin. A little goes a long way and as well as being my favorite hyaluronic acid on the market, it’s probably also the best priced as well.

  • Best moisturizer ever

    Kathleen March 07, 2020

    This oil I feels light and really does the trick. My skin is hydrated and feels great.

  • Miracle Worker

    Maya March 03, 2020

    I’m obsessed with this product. A little bit goes a long way, and the slip and feel of this serum is so soothing. It soaks into my skin quickly, and I follow with the atmosphere protection cream. I wake up from this routine with a glowing, soft, smooth complexion. Osea has a new customer for life!

  • Can't live without it!

    Jayne T. February 17, 2020

    I had to do without it for a while and my skin was so relieved to get the serum
    working again. Just takes a little bit and soaks in and gets ride of all the tightness immediately.
    Follow it with the Advance Protection Cream and I wake up still hydrated.

  • MIRACLE PRODUCT

    Alexa S. January 30, 2020

    I found OSEA from listening to Lacy Phillip’s podcast and got a PING to purchase this serum. In less than two days I saw a difference in my skin. It’s glowing and looks bright, dewy and youthful. I already have pretty good and youthful skin but this has brought it to the next level. I even have my boyfriend complimenting my skin on a daily basis now. I don’t even want to wear make up. LOVE LOVE LOVE this product and will keep this in my must have essentials pile for skincare. I’m also extremely acne prone, hence my hesitation with products but have had no problems with breakouts. Thank you Osea! Feeling like a million bucks. It’s worth the price too. You only have to use a little. It goes a long way!

  • Wonderful

    Anna January 29, 2020

    My skin feels so hydrated and soft after using this. I only use it in the morning but it works all day. Noticeable improvement to my face. Well worth the money.

  • Love at first use

    Stephanie January 20, 2020

    I fell in love with this serum. I apply after using the ocean cleanser and it’s like my skin opens up to receive the serums I apply after. I see a plumpness and brightness in my face that I haven’t had since my 30s. My skin feels calm and fresh. It’s a must for me each morning before apply serums and moisturizer. Paired with the advanced protection cream at night allows my skin to get the moisture it needs without feeling heavy. Definitely a fan.

  • "Did you get botox?"

    Bethany January 19, 2020

    I have always had incredibly dry skin and am no stranger to fine lines and wrinkles at 29 (I have had DEEP forehead wrinkles since I was a preteen). The morning after using the Hyaluronic Sea Serum for the first time I could not stop touching my face – iIt was so smooth and plump! I used this diligently over the holidays and when we came back from break a coworker stopped me in the middle of a conversation and asked if I had gotten botox because my face just looked so youthful. I can’t see a time where I don’t buy this again.

  • Love it!

    Jayne January 02, 2020

    My skin has become super sensitive and I tried the OSEA line and absolutely love it. The Sea Serum goes on easily and only a tiny bit is needed. It feels great on it’s own, but I use the Advanced cream with it.

  • The best!

    Iesha M. December 29, 2019

    As a master esthetician, I’ve tried sooooo many Hyaluronic Acid serums. This is my favorite because it’s clean and non toxic and also gives such great hydration results! My skin feels plumper and more moisturized just after a few uses. This will be a staple in my skincare routine!

  • Hydration

    Megan C. December 21, 2019

    I really like this serum! I’ve noticed a difference in my skins overall texture since using this. I layer the advanced protection cream to help with my winter dry skin!

  • LOVE this product!!

    Carolyn R. December 16, 2019

    I recently purchased a few items from OSEA and am loving all of them! This product in particular has helped with my dry skin that I get every winter. It’s very light weight and doesn’t cause any breakouts. Since using these products, my skin has looked healthier than it has in a long time! THANK YOU OSEA!

  • Moisture magnet

    Jonya K. November 29, 2019

    Love this serum. I get seasonal dryness that in the past, I over moisturize and then will get breakouts due to my combination skin. This serum is perfect, my face is moisturized and clear and I’ve gotten so many compliments on my skin since I started using! I will be reordering and trying other products. Don’t let the price scare you-a couple of drops will cover your face and neck so this bottle will last and allow me to get every pennies worth!

  • Cannot get enough of this serum!

    Vanessa D. November 28, 2019

    A must have serum! (I actually need to get a new one as it fell and broke on my tile floor and I’m missing it in my routine 😫) I love how hydrating this serum is. I can see the plumpness in my skin after using. The softness it gives the skin is unreal 🙌🏽

  • Love the product

    Jennifer G. November 24, 2019

    I love the product. My sensitive skin (including rosacea) looks and feels great. Love the plant-based ingredients. And I loved that they used glass instead of single-use plastic…until I dropped and broke a new, nearly full bottle. I felt like that was $88 down the drain… I poured what was left into a travel bottle, hoping there was no broken glass remaining. Also not sure if the excess air exposure causes the ingredients to break down. Will continue to buy and be very careful. But that’s the reason for the 4 stars instead of 5.

  • Amazing

    Blo June 22, 2020

    I am really liking this serum. We live in Colorado so my skin tends to be extremely dry. This has helped a lot.

  • Not good for my dry skin

    Stacey M. May 31, 2020

    The combination of dry winter weather and my naturally dry skin did not react well with this serum. After a month of intermittent use my forehead was flaking so bad that no matter how much moisturizer I used by the end of the day it was “snowing”. I tried all of the tips to hydrate my skin thoroughly before applying the serum and sealing it with a moisturizer but I think my skin is just too dry for this product. Unfortunately the flaky forehead lasted long after I discontinued use, but the probiotic polish and atmosphere protection cream seems to be correcting the issue. I passed the serum on to my mom but continue to love most of the osea products I’ve tried.

  • Hyaluronic sea serum

    Diane May 19, 2020

    I will purchase this serum again. It is easily applied over damp skin. It has a lovely light fragrance, and absorbs well. I do feel my complexion is brighter after using it, and think there will be continued improvement the longer I use it.

  • Nice plumping benefit but stings my eyes

    Danielle May 17, 2020

    I don’t usually invest in serums because I use a prescription retinol, but when this one went on sale I decided to give it a try since I’m always seeing beauty editors swear by hyaluronic acid. Of course as soon as I ordered it a big story come out about how it can actually be drying and irritating. I decided to see for myself and starting using the serum every night for the past couple of months. My skin is plump and hydrated when I wake up, but I haven’t noticed any major changes. The problem for me is that my eyes sting like crazy and tear if I get the product within an inch of them, to the point where I can’t even keep my eye cream on. My eyes are very sensitive so this isn’t terribly surprising, but it’s enough to keep me from purchasing again.

  • Love Osea!

    Allison May 16, 2020

    I love Osea products! I am 46 and have struggled with skincare my whole life because I have super sensitive and dry skin. Osea products are soothing, don’t irritate my skin and truly moisturize my skin. Also, the smell is subtitle and lovely. You have a super fan in me!

  • Love this!

    Andrea H. May 07, 2020

    I love this serum. My skin looks and feels great when i use this. Even at 60 it make my skin look dewy!

  • Amazing!

    Genea April 21, 2020

    So I really didn’t put enough emphasis on this product during my first go round with Osea products. I skipped purchasing this one because I’d the price. Boy was that a mistake! I love how bright this makes my skin look and I love how it feels. A little really does go a long way! Total keeper!

  • Smooth soft & hydrated!

    Erica April 16, 2020

    This serum has completely healed any dry patches and bumps within a week. My skin needed some time to adjust so if you have very dry/ combo skin give it a chance. You only need the littlest amount to cover my face, neck and chest, about two drops. I immediately after apply a face oil or a lotion for added moisture. Will definitely be repurchasing!

  • The key is application

    Savannah April 10, 2020

    SO I tried this serum maybe a year or 2 ago and didn’t love the results, but I think the application is key! For me, I apply and oil based serum, then I apply the sea serum (with damp skin) and let it dry for about a minute, then layer SPF moisturizer on top! It has definitely improved my skin, which is very prone to dehydration and dryness (lucky me). I think before I was only applying this serum and it definitely wasn’t enough moisture for me, so if you have dry skin, try applying this after a heavier oil based serum. A little goes a long way. Really loving it and happy I gave it a second chance!

  • Amazing

    Claudia March 24, 2020

    Let me start by saying this product is very expensive for the amount you get come on osea. Second, this does do a great job leaving my my skin feeling hydrated and plump. Ive been using it for about a week now and I definitely see a difference.

  • Love this serum!

    Celeste March 22, 2020

    This serum really makes my face soft and I can see a huge reduction in wrinkles after one bottle! My skin is very reactive and products like this usually cause me to breakout and become very red. I did not experience that at all with this product.

  • Obsessed with OSEA

    Katie L. March 21, 2020

    It starts with the beautiful packaging and presentation and then you apply your OSEA products and your skin will literally sing to you. May sound over the top but it’s true, I’m 50 and have tried thousands of products, the purity and healing quality of this hydration serum is wonderful and works very well!! I intend to make OSEA my only skincare line for future I love it!!!!

  • Could not live without!

    Brianna S. January 14, 2021

    This serum feels amazing, like a drink of water for your skin. I apply every day and sometimes use with a facial roller. But it’s so moisturizing and your skin will love this.

  • EVERYDAY ESSENTIAL

    Nicole V. January 12, 2021

    This is my first step after washing with Ocean Cleanser in the morning and evening. I immediately noticed a difference when I began using this serum well over a year ago. It is one of the products that I started with. Highly recommend!

  • So hydrating!

    Nicole J. January 04, 2021

    My skin looks hydrated and plump. I’ve been using for about 2.5 weeks and I can already see how smooth and plump my skin looks. Best thing is my skin absorbs the serum quickly. Highly recommend this!

  • Absolutely amazing

    Mariana December 29, 2020

    This the most amazing facial product I have ever used. I cannot say enough good things. I can really see the difference in my skin, my dark circles are gone, and it gave me a nice natural glow. I’m very picky with the natural products I use, and this product meets all the criteria. I highly recommend it.

  • Hyaluronic serum

    Marie November 21, 2020

    I love this serum. It’s great for preparing the face for the other creams and serums I use.

  • I cannot rave enough

    Samantha November 18, 2020

    I NEVER write reviews but felt compelled to endorse this product because it is just that great. I have super sensitive skin and most products on the market are too heavy, too scented, too aggravating. Within a few days of using this serum my skin felt dewy and fresh and so hydrated. I will never be without it again!!!

  • Love love

    Sarah S. November 02, 2020

    Love this product so much!

  • Evens out skin tone

    Samantha October 01, 2020

    Use this at night & follow up with the atmosphere protection cream. I have very reactive skin, I had 0 issues with this product. It evened out my skin tone ( especially my t-zone) like no other. You have to be careful – a little goes along way! Too much can dry you out( at least for me). I’ve been using Osea for 4 months now, I’ll never buy anything else! My skin looks so good, I don’t feel like I need makeup anymore.

  • LIFE CHANGER

    Julia September 23, 2020

    I am a 24 year old with intense adult acne and this serum has been an absolute life saver. I can instantly feel it deep in my pores and feel like I am at the spa when using this product in my own bathroom. I highly recommend this to everyone!

  • Love, Love this product!!

    Patti September 15, 2020

    I’ve been using this awesome product, HYALURONIC SEA SERUM, for years ~ it’s a true staple in my skincare routine. I basically use it as a ‘base’ after cleansing my face, and then I add my other OSEA products. It’s important to not forget to treat your neck and décolletage area! As a 63 year old, I am very aware of what aging can do to your skin. I do all I can to maintain elasticity and moisture and basic health in my skin, and I will only use the very best products. I research and study products before ever putting a drop on my face, and I’ve never regretted using my OSEA products!

    I top my HYALURONIC SEA SERUM with ESSENTIAL HYDRATING OIL/UNDARIA ARGAN OIL ~ perfect combination for me! I use ATMOSPHERE PROTECTION CREAM as well. People ask me often about my skincare, and I’m always happy to share the beauty and essence of these fine products! No, it isn’t at all too oily or greasy…it’s just perfect skincare. It’s that important to me to use pure products routinely! OSEA products are the best!

  • Nice serum but overpriced.

    Keyshae September 11, 2020

    This is a lovely serum but truthfully it’s incredibly overpriced. Hyaluronic Acid shouldn’t be this expensive.

  • Love!

    Mel August 14, 2020

    I absolutely love this serum! You can actually feel it WORKING. It may sound silly, but it feels like a pair of Spanx for my face..just pulls everything right into place!

  • Superb

    Cheryl July 26, 2020

    Super hydrating on my very dry skin. Easy to use and fragrance free. Absorbs quickly.

  • Hydrating

    Alison July 20, 2020

    WOW has my skin improved since using this serum. I use the “Blemish Prone Essentials” kit as my regular routine and have added the “Hyaluronic Sea Serum” in either the morning or nighttime, or sometimes both. My skin is combination-oily, prone to blemishes and breakouts, and I live in a SoCal which is pretty dry. This serum is hydrating, my skin glows, and I like that the serum is very light. (It is not oily or heavy, like other brands I have tried.) 10/10 recommend!

  • Hyaluronic Sea Serum

    Vicki July 13, 2020

    Keeps my skin dewy and decreases fine lines/wrinkles

  • The BEST

    Alea July 27, 2021

    HANDS DOWN the BEST HA serum I’ve ever used! It truly plums your skin and reduces fine lines and wrinkles. I had some fine wrinkles on my forehead that are GONE now. Everything I have bought fro. Osea is just fantastic! They are an amazing skincare company with great products. I promise you will see results! The price is worth it.and it’s a big bottle so….

  • So good!

    Denise K. July 10, 2021

    Love this stuff. I took a month off to see if it really made a difference…and it really does. My face is definitely more nourished and healthy looking/feeling when I use the serum. I know it can be pricey (I seem to replenish this product more frequently than others), but it’s worth it.

  • Yes, yes, yes!

    I loved upon first use as it is thicker/gel like than any other hyaluronic acid I have used in the past. I became a user for life when I used after microneedling. I have very sensitive skin and after previous treatments, was very red, tight, and sensitive for a solid week using other brands. One use of this and the next day my face was almost back to normal and by day 2, completely healed.

  • MVP of my skincare routine

    Galit June 15, 2021

    I often see reviews for moisturizers from people with dry skin, which isn’t very helpful for someone like me who has oily skin. When osea said that this serum was made for people of all skin types they really meant it! It’s the perfect amount of moisturizing where my skin feels soft and healthy without it being too oily. I’ve been using this serum for about two years now and get so many compliments on my skin (my routine consists of all osea products plus sunscreen)!

  • Lifesaver for dry, sensitive skin

    Chloe May 19, 2021

    I’ve recently been dealing with perioral dermatitis (probably from mask-wearing) and hyaluronic acid is one of the few OTC ingredients my dermatologist encouraged me to use. I bought this product for the first time as I’ve had to temporarily retire retinols and was seeking something both hydrating and anti-aging. This stuff has been fantastic! It’s incredibly soothing to my irritated skin and helps lessen the redness considerably. It makes the healthy skin everywhere else on my face look supple and it generally gives my skin a healthy glow. I really recommend this as a gentle product for those with sensitive/reactive skin. Definitely will be continue using even after my skin stuff clears up!

  • 10+star rating

    Jill R. May 18, 2021

    I have tried many hyaluronic acid serums and none of them have given me the results that this one does. The very first time I used it I could visibly see my skin changing for the better (wrinkles smoothing out and skin is softer). If I could only have one thing from OSEA it would hands down be this product. My dentist even asked me what I use on my skin, because it looked so smooth 🙂 So happy I found OSEA!

  • Awesome product, cumbersome bottle

    Kristy May 14, 2021

    I love this product, the tiniest bit covers my whole face and decollate. My husband keeps telling me I’m glowing and asks what I’m doing so I know it must be improving my skin. I tried a new sunscreen recently and got a bad burn on my chest. This took out half the redness overnight, and the burn was gone in a few days with no peeling or soreness. No kidding! I will always have this on hand for that reason! My only complaint is that the bottle is really cumbersome with the type of dropper bottle used, a traditional pump bottle or larger dropper would be so much better. I do love that it’s glass and not plastic, the dropper is just super awkward.

  • Hyaluronic sea serum

    Mala May 01, 2021

    Love the feel of this serum. It’s lightweight yet very hydrating for the skin. Smooths over skin easily

  • Very Nice Serum

    Emily April 23, 2021

    I took a star off because it really is very expensive for a serum. I do like it a lot. It’s not as miraculous as some people seem to feel. It does have a great jelly consistency. It feels like its going to be heavy going on, but then it soaks right in. It has the tiniest bit of a sticky texture after soaking in which does go away. I don’t know if it is quite worth the money, but it does feel very nice on my face. If it was $20+ less I think this would be the only serum that I would use.

  • removes aging spots!!

    Ellie April 08, 2021

    Love this product – I use it every day. After about 6-10 months I noticed my age spots going away and now after using this product for a year I no longer see them! Definitely recommend!!

  • Gave me a solid routine

    Emily March 22, 2021

    I LOVE this stuff. I have sensitive skin and have been trying to find a routine for years that doesn’t cause breakouts and adds moisture, and that’s a safe clean product. I used to wash my face and use nothing at night because too much moisturizer would cause a breakout. I’d wake up with dry, tired looking skin. I just finished my fist bottle of this and I use it every morning and night. It has helped keep my skin clear, even through my cycle, and moisturized! I don’t have any dry patches anymore. I have switched almost all of my cleansers and moisturized to Osea. I haven’t found anything I don’t love!

  • Hydrated skin

    Julia G. March 05, 2021

    Wonderful combination for hydrated skin:

  • complexion magic without harsh chemicals

    Annemarie March 04, 2021

    for my 54th birthday I bought myself some Osea skincare to replace my usual drugstore junk. This serum really balances my skin which tends to be on the dry side, one drop can cover your entire face. I really love how gentle these products are and how they make my skin feel – smooth and clear. Its magical.

  • Hyaluronic Sea Serum

    Lorraine February 14, 2021

    Excellent product with visible results. I’ve seen a difference in the texture of my skin and a reduction of pore size. This product is worth the investment.

  • Hyaluronic Sea Serum

    Jackie February 03, 2021

    Love this product. So grateful!

  • Experience

    Genieve R. January 18, 2021

    I enjoy the way my skin feels but I was wondering does anyone feel a tithing on your skin after applying the serum sor of like when you are doing a peel off mask? It goes away as the product completely absorbs onto your skin and feels smooth 9nce you applying your moisturizing cream.

  • Love this serum!

    Joanna M. November 03, 2020

    I’m 56 years old with combination skin, rosacea and large pores. This serum is not oily it gives my skin an incredibly smooth, matte, soft fresh look. I wish I found it sooner.

  • I love this product

    Amy B. June 18, 2020

    I have combination skin and extreme allergies to foods. My food allergies are so severe that finding a facial cleanser and moisturizer is nearly impossible. I finally found Cetaphil Sensitive skin for a cleanser and I have to use pure aloe vera gel as a face lotion because there are virtually zero moisturizers that do not contain gluten, dairy, nuts, sugar, and artificial sweeteners. This is the first moisturizing product/brand that I have EVER found that has a product that does not contain glycerin, ethylglycerin or glyceril stearate (all contain sugar). I dropped my $88 so fast without even trying the product out. My face is combination, meaning some parts are dry, others oily. I started using this serum last week and I use it after I cleanse and tone. I follow up with my pure aloe vera gel as a moisturizer. I didn’t notice the difference right away but now in Week 2 I am seeing a plumpness and hydration to my skin that I haven’t seen in ten years. The products I can use do not give my skin the moisture it needs and it is so cool to see my cheeks look plump and the skin under my eyes looking juicy and moisturized for once in my life! Now I’m noticing that my skin may be too hydrated in certain areas. I was using two drops of the serum last week and so I switched to one drop both morning and night and I am loving the results. I can tell this is a product that builds up over time, meaning you may not see all the results right away and you may have to adjust the amount of product you use to get the result you want. For me, this is so exciting. I am so happy I found something that gives my skin some moisture and love. It’s been so hard for me. I am starting to look through the rest of the Osea brand and finding there are only a few products that I can use but I am so happy that I can use them! Imagine seeing all these fantastic products and never being able to try them! That’s me, so to be able to try this product and see it work is a miracle.

  • Love!

    Kristen May 08, 2020

    This will make your face look so plump and fresh! This is a key staple in my skin care routine!

  • Not moisturizing

    Alyssa September 23, 2019

    This product is not moisturizing. I use as directed and it has been drying out my skin. I’ve been using it for ~2 weeks and almost immediately noticed a difference in my skin. Will not be purchasing this product again.

  • Not sure just yet.

    Lauren P. July 12, 2019

    I cannot really tell if it’s making a difference. It’s way too expensive for results that are not apparent. Will search for a different product once this one is used up.

  • Amazing - highly recommend - buy!

    Mary C. July 12, 2019

    High quality, gentle yet effective, non-toxic, glass bottle wonder. I see a *huge* difference in my skin when using this (tone, texture, inflammation, redness, softness). I apply it every evening then apply the OSEA night cream. Will never go back to my old toxic routines.

  • Great serum

    Rachel H. July 12, 2019

    It is super hydrating for my face but to me smells kind of Earthy (seaweed is one of main ingredients). Other than that it is wonderful!

  • Love it

    Alicia April 23, 2019

    I love the slip of this serum. It’s very hydrating and leaves a smooth canvas behind. It’s slightly mattifying and I kind of like a glow which is the only reason I gave it 4 not 5 stars.

  • A great hyaluronic serum!

    Michelle H. April 22, 2019

    If you are familiar with hyaluronic serums and know you want one that’s also better for you and the planet, you should definitely invest in this. I’ve struggled with finding the correct moisturizer for my entire life until about a year ago when my dermatologist told me to try a proprietary serum. I slowly shifted from that serum to Osea’s, and now I wouldn’t use anything else for my skin. It moisturizes the perfect amount without leaving my face oily or sticky (although it does feel sticky on your fingers, when it dries on your face it doesn’t!)

  • Just ok

    Erin M. January 09, 2019

    I like this stuff; wouldn’t say love…it’s a tad sticky and I haven’t noticed a huge difference yet but will continue to try it out.

  • Great boost!

    Stacey C. January 02, 2019

    I’ve been switching all of my skincare to cruelty free + vegan products so I gave this one a try on someone’s recommendation. I was pleasantly surprised at the size of the bottle when it came. I put it on under my moisturizer and I love how it feels on my skin. Will definitely buy again!

  • My new favorite product

    Alexa G. October 17, 2018

    Highly recommend this one!

  • The Best Lightweight Hydrator

    Sarah M. September 25, 2018

    I love this lightweight hydrator! It’s super easy to dose with the dropper. I apply it in the morning after I wash my face. I got a tip from one of the store associates to mix this with the True Botanicals Vitamin C powder booster and I love the combination. It gives me lightweight hydration and a glow. I follow it up with a daytime moisturizer with SPF. For hot, summer days, it would definitely be enough moisture for my skin by itself.

  • Give your skin a drink!

    Rachel M. September 04, 2018

    Found this product during a phase in which my combo skin started feeling extra dry and irritated. Gives my whole face a drink and balances out my oil and dryness. AND it is one of the first hyaluronic serums that doesn’t leave my face feeling sticky!

  • Fast absorbing

    Olivia B. August 31, 2018

    I have really dry skin and my skin drank this stuff up. It’s crazy how fast it absorbs. If your skin is really dry, you’ll need to use an oil or moisturizer afterwards because my skin felt super tight after.

  • If you have dry skin, you need this!

    Lauren B. August 29, 2018

    Amazing serum for dry skin! It really does help my skin to feel more hydrated and nourished. Make sure you layer under your regular moisturizer. It is intended to be a concentrated treatment, not a moisturizer. You will notice that it helps your hydrating steps to work even better!

  • My favorite serum

    Michael M. August 28, 2018

    I’m obsessed with this serum. It’s so gentle and lightweight, applies like a satin smooth gel and helps lock in moisture from my hydrating mist! It’s so great underneath my youth dew facial oil! Will definitely buy again.

  • Not Super Moisturizing

    Minta August 25, 2018

    I want to like this product and layer it under my moisturizer…however, my skin still feels tight and not super dewy or moisturized. I will continue to try to work with it, but not likely to repurchase as it doesn’t seem to add any hydration to my dry skin.

  • Plumping

    Elizabeth D. August 24, 2018

    After I use this and apply moisturizer my skin is super plump and dewy but never sticky. Will purchase again.

  • Smooth

    Jenna M. June 01, 2018

    This is a nice smooth addition to moisturising. It is light and thin and absorbs right into the skin and really locks in moisture.

  • Soo drying

    Dana March 17, 2018

    I don’t understand this stuff and how people say it’s moisturizing. I feel like I must have gotten a dud bottle or something. It is so incredibly drying. It makes my skin feel flaky and crusty and tight almost instantly About 10 minutes later I can rub my cheek and flakes of skin and product start coming off in large amounts but after I don’t feel smooth and moisturized, I just still feel dry. It’s awful. I wish I hadn’t thrown away the packaging. It’s so expensive to be so terrible.

    • From Follain:

      Hi Dana, I would be sure to use the serum under your daily or nightly moisturizer for the serum to take on its full effects! The serum shouldn’t be used alone but with your moisturizer layered on top for an extra boost of hydration!

  • Great for layering

    Jess March 08, 2018

    This is a great surge of moisture. I’m using it after cleansing and a mist but before serums, oils/moisturizers. Should I be layering it on top of water-based serums instead of underneath?

  • Very drying

    Heidi H. February 27, 2018

    I didn’t find this product very moisturizing or plumping. However, rereading the HINTS: I will add it as an extra step after cleaning and before moisturizing.

    • From Follain:

      Hi Heidi, yes! This works great as a moisture boost to your everyday moisturizer by applying it after cleansing and toning and then adding in your daily or nightly moisturizer on top!

  • From Dry to Dewy

    Wynne L. January 31, 2018

    Takes my dry, parched winter skin and instantly gives me a dewy glow. Super light-weight and a MUST step in my skincare routine before oil and a moisturizer

  • Best serum

    Sara N. January 25, 2018

    This might be my most favorite product from Follain ever. I use this serum every night, sometimes adding the True Botanicals Vitamin C Booster, and it has definitely made a difference in my face. Lines are diminished, and my skin is smoother and calmer. Will definitely be purchasing again!

  • Love this acid

    Monica L. December 30, 2017

    This hyaluronic acid works wonders as it has pure ingredients. I use it in the evening and wake up with supple skin. My only criticism is the glass container – is easily shattered. I dropped mine in the sink and shattered the glass. Would be great to find out the percentage of the hyaluronic acid.

  • Love this!

    Sasha November 16, 2017

    I’m a huge fan of this serum. I find it absorbs immediately, and a little bit goes a long way. It provides a great moisturizing base for my other skincare products.
