AMAZING
Love this vitamin c it’s really helping with my melasma!! All the reviews that are saying the packaging is deceptive are we okay? it’s an airless pump container but it has 30ML it’s illegal to say a product is 30 ML and then be less… use your brains and use less product

Repurchasing
I really like this vitamin C serum. I have sensitive combination skin and live in New York City. This serum doesn’t irritate my skin and actually makes a noticeable difference. Will definitely repurchase!

I’m already pleased with the results of the Pro C Serum by innbeautyproject. The Vitamin C, Ferulic acid, and peptides have made my skin appear brighter and I can already see spots on my face fading. The airless packaging design is ideal since I’ve had experience with other brands Vitamin C skincare products oxidizing fairly quickly. For this level of ingredients, I’ve seen other products priced much higher. Overall, my skin already looks improved and clearer.

Must have!
I absolutely love this serum! It has worked wonders for my skin! I really like the lightweight formula and texture, it goes on smooth without feeling heavy. It's gentle enough for my skin which can get irritated easy and with consistent use my skin looks brighter and healthier! This is a must have in my skincare routine!

It actually works for me!
I’ve been using Innbeauty for years so it was no surprise I’d absolutely love the Pro C Serum. I honestly can’t believe how quickly it has faded some of my largest dark spots that I thought were permanently on my face forever. So when they say this serum is clinically proven to fade dark spots, hyperpigmentation, as well as reduce melasma and sun damaged skin, I can say that is 100% true! I paired this serum with the 10+10 moisturizer, which I happened to already have. I am absolutely shocked at what a difference this combination has made to my skin, it truly feels and looks younger! After using this my skin is so glowy, bright and I finally feel more confident! I can’t be without this must-have serum in my everyday skincare routine from now on!

Found a vitamin C that doesn’t irritate my skin AND works — rare. Love the ingredients here: 15% THD vitamin C + hyaluronic acid + green tea. No sting, no funky smell, and it stays stable. It’s a lightweight gel that sinks right in and plays nice with my moisturizer + SPF. Noticed my skin was brighter and more even-toned around week 3. Amazing for sensitive skin. Airless pump is a plus. Kinda pricey, but it lasts forever so I’m repurchasing.

comparing to skinfix via c
Was using skinfix vit c and wanted to give this a try. Used whole bottle. Big heavy glass bottle which doesn't lend itself for travel. Had to use more product--didn't spread as easily. A bit more cream-like and less serum-y than skinfix. Wasn't compatible with all skincare and makeup (pilling). I will go back to skinfix. Otherwise, it was fine but I have something I prefer otherwise. As far as how my skin reacted--didn't notice any positive or negative changes.
