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"

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"

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"
