Hyaluronic Sea Serum
Size: 1 oz
- Hyaluronic Acid floods skin with moisture

This serum provides a burst of hydration for all skin types with three molecular weights of Hyaluronic Acid and age-defying seaweed extracts.

We’re starting to believe this product is the fountain of youth.

Love this serum!
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
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.
This will make your face look so plump and fresh! This is a key staple in my skin care routine!
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.
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!
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.
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!
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!
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!)
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.
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
Highly recommend this one!
The Best Lightweight Hydrator
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!
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!
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!
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
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
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.
After I use this and apply moisturizer my skin is super plump and dewy but never sticky. Will purchase again.
This is a nice smooth addition to moisturising. It is light and thin and absorbs right into the skin and really locks in moisture.
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.
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
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?
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.
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
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
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
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.
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.
