Rated 5 out of 5 by carboni from I love love this vitamin C serum. Im in my 20s and I dont need a super high % of vitamin C yet. Its great for a starter or sensitive skin. Its really thin and a little too watery to handle. Smells like vitamin C, which is rubber and Hot dog water... but I highly recommend.

Rated 4 out of 5 by ann3p4 from I started using this serum about three weeks ago. It’s recommended as similar to their CE Ferulic serum but if you have sensitive skin, and it’s the lighter version. I didn’t notice a huge difference but I’m guessing that’s because it’s not as strong. I use it in the morning under sunscreen and the difference I notice is subtle but enough that I want to try the stronger version. It makes my skin very smooth and evenly textured. Without it, it feels rough. I recommend trying this if you want to see what vitamin C does for you skin, I’m guessing it’s a little different for everyone. This version also isn’t as big of a financial commitment as the other one I think it’s about half the price.

Rated 5 out of 5 by Damla from Perfect for my sensitive skin I have been using this vitamin C serum for a month now and I am extremely satisfied. I used vitamin C products from other very well-known brands in the past and I always had issues such as dryness, redness and irritation. So I stopped using vitamin C serums. When I saw this product on Skinceuticals I wanted to give it a try. I am happy to say the level of vitamin C (%10) is perfect for my sensitive skin and it gives a very nice glow. It's amazing to see how my skin quickly absorbs it and feels really good. This product is now a part of my skin regimen and I will definitely continue to use it.

Rated 3 out of 5 by Haletta from Want to love... I bought this because I have very sensitive (but early 40’s beginning to age) skin. I’ve been looking for a gentle, yet effective way to incorporate vitamin C into my regime and love Skinceuticals. Sadly, the bottle that I purchased is very dark yellow with a strong odor, which leads me to believe it’s oxidized. How can I get a fresh bottle to ensure maximum benefits?

Rated 5 out of 5 by ashleyk from Bought on dermstore- I am so grateful this exists So grateful this product exists. I have sensitive acne-prone skin and all the ingredients in this are safe- no alcohol, no unnecessary pore clogging ingredients, and a gentler percentage of active ingredients. All you need are a few drops! Love love it

Rated 3 out of 5 by Anonymous from Too thin to apply I would like this much better if it was a serum, but it's a pure liquid. It's like trying to apply 4 drops of water evenly to your face. Wouldn't purchase it again. Have only used it a few times so I can't speak to any results.

Rated 4 out of 5 by kccae4 from Nurishing and non irritating, which is exactly what I was looking for. I will likely repurchase but may hesitate due to the price. I like that the packaging is glass. I like products that have actual scientific studies backing their claims. But this product did not really help with dark spots like I was hoping it would, but this is one of the few vitamin c serums I have been able to use without massive breakouts occurring. I am just about to finish my second bottle. May go for one of the stronger versions next time.
