Reviews

Instant Glow

"#gifted by innbeautyproject for a while now, vitamin C has become an essential step in my skincare routine because I’ve actually seen real improvements in my skin. So I’ve taken the time to do a lot of research, read forums, and look for the ones with the best reputation. I came across this serum because it had so many good reviews, and honestly, it has lived up to what it promises. I do feel like it’s worth the price, especially for how radiant and luminous it leaves my skin."

— Jeniffer (5/5)

Amazing formula

"I've been using this vitamin C serum for over two weeks now and I'm loving the results so far. I've noticed my hyperpigmentation and dark spots fading but also my skin texture is smoother and more brighter. The formula feels so soft and silky. It doesn't irritate my skin at all. I received mine complimentary from InnBeauty Project"

— Laurel (5/5)

Healthy glow in a bottle

"complimentary from INNBEAUTYProject I've tried quite a few vitamin C serums over the years, so I had high expectations for this one - and it genuinely impressed me. The formula feels lightweight, absorbs quickly, and layers beautifully with the rest of my skincare without feeling sticky or heavy. After using it consistently, my complexion looks noticeably brighter, healthier, and much less dull. My skin tone appears more even, and it has that natural glow I usually only get after a really good night's sleep. I also appreciate the refillable, airless pump packaging - it keeps the product easy to use while helping protect the formula. Compared to many other vitamin C serums I've tried, this one feels more elegant on the skin and has quickly become one of my favorites."

— Eva L. (5/5)

Already fading sun spots

"I’m already impressed with the immediate results that the Pro C Serum gifted by innbeautyproject is providing after only a few uses. The Vitamin C, Ferulic acid, and peptides are assisting with making my skin brighter and fading sun spots. I like that the airless packaging design will allow this product to last longer because I have had vitamin C skincare quickly oxidize in the past. Additionally, I see products on the market containing these ingredients for a much higher price. Overall, my skin looks clearer and brighter after only a few uses."

— Jen (5/5)

Brighter skin

"This serum goes on super smooth, no burning, no weird smell, just straight up brightening energy. After a couple weeks my dark spots started looking way less loud and my skin tone looked way more even. It’s giving I drink water and mind my business even when I absolutely do not. complimentary from innbeautyproject"

Love this gentle serum

"This is gentle vitamin C that actually works. I’m very impressed with the ingredients- 15% THD vitamin C + hyaluronic acid + green tea. No stinging, no orange smell, no oxidation. Lightweight gel that sinks in fast and layers well. Saw brighter, more even skin in about 3 weeks. Great for sensitive skin. Airless pump keeps it fresh. Only con is price, but it lasts. Repurchasing for sure. gifted by innbeautyproject"

— Cassie (5/5)

Such a great brightening serum

"I love the active ingredients in this serum and how smoothly this applies to the skin. I had dark and dull spots on my face and the Vitamin C 10% in this definitely did wonders for my skin. My skin feels brighter and I have a more even complexion. I love that the container is refillable and how easily the pump works to dispense the product. If you’re looking for an overall brightening for your face, this is a game changer! Gifted by innbeautyproject"

— Brittney (5/5)

Works well

"Thoroughly enjoying the vitamin c I was gifted by Inn Beauty Project. The formula is extra silky and I feel like it soaks so well into my skin. It’s comfortable to wear both day or night and I find it pairs well with other skincare and wears well under makeup. It doesn’t leave my skin irritates and I feel like my skin looks so much brighter"

— Amanda (5/5)

A Brightening Serum That Feels as Good as It Works

"I’ve been really enjoying the INNBEAUTY Project Pro C Serum! The lightweight formula absorbs quickly without feeling sticky or greasy, making it easy to layer under moisturizer and sunscreen. With 15% Vitamin C, ferulic acid, and acetyl glycyl beta-alanine, it helps brighten my complexion and gives my skin a healthier, more radiant look over time. The refillable bottle is a thoughtful, eco-friendly touch, and the packaging feels sleek and premium. If you’re looking for a vitamin C serum that leaves your skin feeling fresh, smooth, and glowing, this one is definitely worth trying. Gifted by innbeautyproject."

Works

"Gifted by innbeautyproject, the innbeauty vitamin C brightens and lightens with one serum. Advanced liposomal Vitamin C technology helps penetrate skin better which leads to better skin texture and pigmentation. After a few weeks my skin looks brighter and dark spots less evident."
