Customer Reviews

  • Incredible results!!

    Amanda W. August 04, 2021

    I suffered from acne in my early twenties and after it cleared up I was left with scars and blemishes. This brightening serum transformed my skin! After 3 months of use my blemishes are 90% gone! Follain, please don’t ever stop making this product! I’ll be purchasing it forever!

    • From Follain:


      We are elated to hear that our Brightening Serum has been so effective for you and has transformed your skin! Thank you for your feedback and we will absolutely continue to offer the most effective clean products for all.


  • No Fragrance = good, sticky = bad

    Courts March 12, 2021

    I like the lack of fragrance because it’s clean and fresh. It’s cool going on but feels rather sticky, so much that it feels like a mask that I want to wash off right away.

  • Sticky

    Sandra March 14, 2021

    I was not that big of a fan for the brightening serum. It made my face feel sticky and it had a burning feeling on my skin.

  • Definitely works

    Mm March 03, 2021

    I have noticed significant brightening of post inflammatory red marks from acne scars. Been using about a week now. One thing I would say I didn’t care for but is veryyyy minor is the consistency, more of a liquidy serum. I prefer more of a gel like consistency for serums but again that’s personal preference.

  • Skin felt a bit dewy

    Texxasgurl45 March 07, 2021

    This Brightening Serum is pretty decent. In my night time routine, it was good, but it’s not the best in the morning routine. It made my skin feel dewy and a tad bit sticky. It’s gentle in the skin. I did feel like my skin had somewhat of a glow after using it. It looked nourished. It absorbs quickly and doesn’t leave my skin oily. I just wasn’t too fond of the dewy texture on my skin. We’re all different and some may like the dewy look/feel.

  • Vitamin C Boost

    Grandyae March 07, 2021

    Doesn’t smell the best. I have only used this product for a few days so I haven’t seen a difference yet. No break outs o far so good

  • Very good

    Dana March 12, 2021

    I like this product a lot it is very liquidy it comes out like water. I haven’t used it long enough to see a significant difference but having vitamin C in my skin care routine is beneficial. I wouldn’t necessarily call it a serum because of its consistency but it works very well underneath make up because it is very thin and absorbs quickly.

  • Fantastic addition to my regimen!

    Alid123 March 14, 2021

    It’s a little clammy and tacky to use in the morning, but I’m so glad I added this to my nighttime routine! My skin looked and felt better after just the first few applications.

  • The perfect serum doesn't exi....

    Littlemissfelina March 01, 2021

    Seriously the perfect, lightweight serum!!!

  • Lightweight and works quickly

    Vonnysam March 03, 2021

    I love this lightweight serum; for some reason, I was expecting it to be thick in texture, but it is very light with a water-like consistency. It readily absorbs into the skin and gives the skin an instant glow as well. This is a fantastic, brightening booster.

  • Amazing

    Maricruz March 03, 2021

    Its amazing .. Seriously the perfect lightweight serum! & Yes, I would recommend to a friend & family

  • Great Serum

    Kherma3 February 28, 2021

    I’ve been looking for a new serum that was made from natural ingredients and included vitamin c and I’m so glad to have found exactly what I was looking for in a skincare serum.

  • Love it!!

    Leah27 February 28, 2021

    Follain Brightening Serum- Vitamin C Boost has helped my skin so much. My skin looks brighter and healthier. I have a rosy glow to my cheeks now. I can see an improvement in my acne and my pores are less noticeable. I like that this serum has a pump top. It’s easier to use and get the right amount. I love this serum and will definitely purchase it again. I would are it to anyone who wants a brighter, healthier complexion.

  • Feels like nothing on the skin

    Ms_lizzz February 27, 2021

    I look for several things when choosing vitamin C products, and this serum checks off all of them. The packaging is opaque, which preserves the integrity and potency of the product. It doesn’t sting, which is important to me because I tend to use my products with derma rollers and Retin-A. It doesn’t really have a fragrance or any chemical smell to it which avoids irritation. It also has a great colorless water-gel-consistency, fully absorbs in seconds and doesn’t leave any sort of film on the skin, not greasy or oily and also not dry. It layers perfectly under my other products, and I will continue to use it on my combination 34 y/o skin.

  • Follain Brightening Serum

    Datx2 March 05, 2021

    Follain Brightening Serum Vitamin C Boost has been a game changer for my skin! With 1 pump all over my face and neck, it’s fast absorbing & silky feeling leaves my skin radiant and an evened skin tone.

  • Vitamin See!

    Babydoublej March 06, 2021

    I have ultra sensitive skin, and I have to be careful about which products I use on it. There are SO many different brightening serums out there, it can be almost dizzying. Follain Brightening Serum Vitamin C Boost is exactly what my dull, lackluster skin needed. It is a clean beauty product, cruelty free, and dermatologist recommended. After cleansing my skin, I just applied one pump all over my face and neck. I was really scared it would break my skin out. It did not! Instead, it gave my skin a glow that was not greasy or oily. It also was not sticky like some serums. The citrus scent was also a major mood booster! It is extremely gentle, and I patted it into my skin. My skin just soaked up the serum. I followed it up with moisturizer and SPF. I love the way it makes my skin just look better! It helps even out my skin tone, too. This is like sunshine in a serum! I’d recommend this to anyone who wants a little more glow in their life without all the fuss.

  • Glowing skin!

    Izzytug March 07, 2021

    I’m a big fan of having a Vitamin C booster in my skin routine. I see such a difference in my skin using this! My skin is glowy and my scars are diminished. It absorbs nicely into skin, and provides a nice foundation for makeup.

  • Works great

    Ashley March 07, 2021

    I’ve been using this for two weeks and have noticed a good amount of change. I will definitely continue to buy

  • Refreshing moisturizer

    Jillp82 March 07, 2021

    The Follain Brightening Serum_ Vitamin C Boost is a great product! I have been using for about two weeks and I’ll tell you since I been using it has really made my face feel refreshed! It truly has brought some life back into it; it doesn’t have a dull look. I was feeling life my face was just losing moisture and elasticity but it’s really starting to make a difference….

  • Scent free treat for the skin

    Stelande March 07, 2021

    I have really enjoyed using this serum. I love that it is truly scent free. It is very thin and is easy to apply evenly. I am very happy with its performance and would recommend it to others.

  • I love Follain!!!

    Katdragongal March 08, 2021

    Thank you BzzAgent and Follain for sending me this wonderful Brightening Serum with Vitamin C Boost!!! I love all the transparent and non toxic organic ingredients that is in this serum. I also appreciate the ethics of creating this formula. This serum delivers Brightening results without irritating your skin. I would definitely recommend this to everyone, especially people with sensitive skin. It’s a must try!!! Love this serum.

  • Follain Brightening Serum

    Blair199120 March 08, 2021

    Thanks to Bzzagent, I received Follain Brightening Serum, complimentary, in exchange for my honest review. This product is like an all-in-one or all-inclusive serum. Quickly absorbs into the skin, leaving no oily or greasy leftovers, very light, airy, and soothing to use. Lackluster, dull skin has NO chance after applying this product! Dramatically brightens skin from 5 fruit sources of Vitamin C, while significantly reducing the appearance of pigmentation, leaving an all around healthy and balanced skin microbiome!

  • Like the product

    Yaze1303 March 09, 2021

    While I am using the product until I finish it I never leave things halfway I thought it was a dropper when I saw it but it is a practical pump the liquid is transparent it makes me very liquid that others feel fresh on your face and it does not have much odor it is absorbed quickly It is not sticky I would prefer it to be a little more creamy thanks I received it for free to try

  • You can't go wrong.

    Gful March 08, 2021

    You can’t go wrong with this product. I have noticed that my dark marks have lighten up bad they are looking better. I am very impressed with this product and how quick it started working. And how good my skin looks.

  • Glowing skin!

    Belita0984 March 08, 2021

    Follain Brightening Serum Vitamin C Boost leave any face looking so bright! I love the texture this serum has and I love how it dispenses from its little bottle. So easy to use and works great. It leaves me glowing.

  • I love it

    Miss C. March 09, 2021

    This product has a nice texture and non greasy feel. It also has a nice smell that is citrusy but not overwhelming. I’m really looking forward to long term results since I have hyperpigmentation. However, in just a weeks time, I feel like I already see a difference! I also really love that it has prebiotics that will improve the health of my skin overall.

  • Amazing serum!

    Meg March 09, 2021

    I loved the way this serum made my skin feel. After just once use I noticed brightened skin, and the effects have continued the more I’ve used this product. I’ve tried a lot of vitamin c products, and so far this is my favorite one because it’s both gentle and effective!


    Cakefacebrit March 10, 2021

    Follain Brightening Serum has been a lifesaver after a week and a half of using it and I already notice an improvement in my skins overall appearance. I have brighter skin and I have noticed my pores are literally almost gone completely. There is natural fruit derived AHA’s inside of the ingredients which helps exfoliate the surface of your skin which I can assume is the reason my skin is soft and poreless! I will definitely be keeping this serum as apart of my skincare regimen from now on. Who wouldn’t when your skin looks this darn good? 😉

  • Really Brightens

    Bbymon March 11, 2021

    This is my first time trying skincare by Follain. I like this pump bottle and 1 pump dispenses the perfect amount for my face. It is a wet , clear texture that absorbs pretty fast. I apply this before my moisturizer for a smooth base before applying makeup. This really has brightened my skin tone after just a couple days use. I plan to keep using this because I like the results from the Vitamin C and Niacinamide. This does Not irritate my skin and is unscented. I also like that this is clean beauty and cruelty free! Highly recommend!

  • This brand needs more recognition!

    Luzg March 12, 2021

    I read about the brand and their ingredient guide is phenomenal! I was quite impressed of how detailed they are in their harmful ingredients guide. As far as the product goes it doesn’t sting or irritate my skin in spite of it being vitamin c compared to the suspension I’ve used which leaves my skin red and sensitive. I was expecting something thicker but it is very light and liquidy, it sinks right into the skin and absorbs pretty quickly like water. It is so gentle and refreshing, I’ve used it for more than a week and I already can tell the difference, my skin feels so soft, clear and supple. I think that along with sunscreen I can tell this will be a staple in my skincare routine.

  • Great Product

    Mycraftyzoodotcom March 14, 2021

    I applied every morning before my normal face bream and it did a great job of brightening and and enhancing my skin. Absolutely love it and it will be a continued part of my morning facial care for sure!

  • Loved the smell

    Kyky March 14, 2021

    This brightening serum really worked. I liked this a lot. It was definitely a plus that it had a nice scent to it.

  • refreshed

    Rainy March 15, 2021

    I have been using this daily now for a week or more. I noticed that a little goes a long way when applying the serum. There is so much in the bottle that I know it will last for a long time. I love the soft sent and the smooth feel that comes with regular use.

  • Follain Brightening Serum_ Vitamin C Boost

    Tucsontucson March 22, 2021

    This serum can be used day or night. It has a citrusy scent and skin absorbs it easily. I use after cleaning my face. It’s vegan and cruelty free also. I definitely would recommend if your looking for a serum that hydrates without a sticky finish.

  • Amazing For Dark Under Eyes and Lackluster Skin !!!

    Rox March 16, 2021

    Wow! What a bright boost to dark under eyes and lackluster skin. Winter can really suck the radiance right out of you and it shows in your skin. Follain Brightening Serum Vitamin C Boost revives lifeless skin and gives it a mositure boost without being greasy or slimy. Can use day or night, and under makeup. Love, love, love. This one is going to be added to my regular skin routine.

  • Wonderful!

    Megansdesignedlife March 16, 2021

    The Follain Brightening Serum helps my skin look brighter and have a beautiful glow to it! It also is so refreshing to use in the morning and at night!

  • Gentle Vegan & Cruelty Free Vitamin C Serum

    Cocoabuttermama March 16, 2021

    I like it. Watery formulation so be careful with the pumps but it goes on easy and doesn’t dry tacky. I let it dry before adding my creams or moisturizer and it settles well underneath. I need to use longer to see deeper work on my hyperpigmentation but I do think my skin looks more healthier and radiant overall

  • Clean & Refreshing Vitamin C Serum!

    Alyee March 23, 2021

    From the moment I started using it, Follain Brightening Serum Vitamin C Boost has been a wonderful addition to my skincare routine. I’m getting a bit older, near my mid-thirties, so now more than ever I highly invest my time and money into good skincare. This serum’s formula is watery, but goes on smooth and soaks immediately into my skin. I also appreciate using a mindful approach as the directions suggest, taking a couple of deep, slow breaths while gently rubbing it into the skin before moisturizing. There’s also no tackiness to this Vitamin C serum, and after applying to the face and neck, it makes my skin soft. Plus, it produces a soft glow and smooth-to-the-touch feel. While it’s meant to have a natural citrus scent, it’s so faint that it’s basically scentless to me. I’d never heard of Follain before, but now I’m intrigued with this clean skincare line! I received this complimentary and all thoughts are my own.

  • Brightening

    Rachelw March 23, 2021

    I was pleasantly surprised with this serum! After using for about a week I noticed a noticable difference in my skin. It was no longer dull. I have a nice youthful glow to my skin now. Its definitely hydrated and has helped me to wear less makeup.

  • Silky smooth skin

    Dee March 23, 2021

    I love serums and this one is on par with others that I use. Barely any scent which I enjoy. I like that it absorbs into your skin but also has a very moisturizing silky feeling effect. Very nice product with pretty packaging. Vitamin C products always take a while for me to see any brightening affect maybe that’s because I have medium skin tone not sure but I’ll keep using.

  • Love it!!!

    Sweetdeseos March 28, 2021

    The Follain Brightening Serum is so amazing! It is extremely lightweight and it absorbs into the skin almost immediately! It doesn’t have a noticeable fragrance but you definitely see the results, it leaves your skin feeling smooth and bright after a few uses. You just need to remember to use sunscreen to protect your skin in the daytime.

  • Lightweight and Absorbs Well!

    Lauren March 28, 2021

    I love that this serum is made with ingredients that I feel good about using on my skin. It absorbs well and has made some dark spots appear lighter after a couple weeks of consistent use. There is no artificial fragrance which is also awesome.

  • Love!

    Sami June 14, 2021

    Vitamin C is a staple in my skincare routine and when I ran out of my last serum I decided to try Follain’s! This is super light, absorbs quickly, and like other reviewers have said, it’s not sticky. I experienced no irritation as someone with sensitive, acne-prone skin. My only critique is that I wish there was more transparency on the percentage of niacinamide in here. I use another product with the ingredient and asked customer service for specifics and was given a non-answer.

  • Nice product but sticky

    Angela D. June 02, 2021

    I like this product and have found the results to be on-par with some of my other Vitamin C favorites. I love the addition of niacinamide too. My only complaint is that my skin feels a little bit sticky after application and I often have to wash my hands after using it. This happens regardless of whether my skin is damp or dry.

  • Game changer

    Brittany March 26, 2021

    I tend to have oily skin and wasn’t sure about using this serum because I’m always afraid of breakouts. I started off using only at night but quickly added it to my morning routine because it makes my skin so glowy without the greasiness. I’m very impressed with how well this serum works.

  • Effective for Sensitive Skin

    Vicki P. March 22, 2021

    As a life long acne sufferer with sensitive skin, I’ve come to be skeptical of a lot of products. This one amazed me. I noticed a decrease in the redness in my complexion within just a few days, and I wasn’t feeling any of the sensitivity I often do with new products. I’m excited to see what this can do in the long run.

  • Wonderful vitamin c serum!

    Christina K. March 18, 2021

    Really love this lightweight serum, it doesn’t have a smell and I’ve been using it for the better part of a month once a day and have seen significant improvement in hyperpigmentation from acne scars. Leaves you with a glow, too!

  • A Bright New Look

    Marilynn C. March 07, 2021

    What a boost to my day the new brightening serum has been. Before I tried it, I felt I had to apply makeup early in the day to look alive. However, with this serum, I find it leaves me with a fresh, clean look. To speed its absorption, I use the toning mist first. Now some days I find I go makeup free.

  • Not Sticky!

    Sarah February 26, 2021

    My issue with C serums in the past is that they left my skin feeling sticky before putting on moisturizer. This formula is NOT sticky at all and feels great on my skin. It’s been a week now after using it every day and I already feel like my skin is brighter. Very happy with this product. Great pricepoint, too.
