clinical study
Studies show that when formulated properly (as all SkinCeuticals antioxidants are), a 10% concentration of L-ascorbic acid is readily absorbed by the skin.
Formulated with AOX+ advanced antioxidant technology, this lightweight, fast-absorbing serum combines ferulic acid with 10% pure vitamin C to enhance antioxidant performance.
Innovation 1
L-ascorbic acid has a reservoir effect, which means it can’t be washed off or rubbed off for a minimum of 72 hours.
Innovation 2
The addition of ferulic acid stabilizes and enhances the absorption of vitamin C.
Once in the morning after cleansing, apply 4-5 drops to a dry face, neck and chest.

It is normal for vitamin C products to darken after opening due to air and light exposure. Any change in color does not affect the product's efficacy.

Great results I have used SO many products trying to make my skin look better. I have used the SkinCeuticals daily moisturizer for about a year now and it is really great for my sensitive skin. I started using this serum at the recommendation of my esthetician, and love it. I moisturize in the morning after cleansing and use the serum at night after cleansing. I love the way it makes my face look and feel. I have acne prone skin and this product does not bother my skin in the slightest. I have had so many problems over the years with other products. Happy to have this product and I will continue to purchase this. October 7, 2013
Genie in a bottle This product is simply amazing. It works! I've been using it for 4 years now and the results now are as good as ever. When I first started using this produce, within a couple of weeks people noticed the glow in my face and I did too. Years later, people still raise a brow when I tell them my age. Highly recommend this product to everyone. July 11, 2013
Glowing! I've been using this product for a few weeks every morning. First I apply a liquid anti-blemish solution, followed by this, then sometimes a lightweight, oil-free moisturiser, and finally, always, a cream formula sunscreen of SPF 30 for sensitive skin. I do notice a glow on my face after having started to use the serum 10. It is nice, but I've also noticed more of what look like comedones on my cheeks. I'm wondering if it's cos I'm piling on too many products on my face?? or if this product is not suited for my skin type. I have oily, blemish-prone and sensitive skin. Also, as I spent a lot of time outdoors, espeically mid-day, I wonder if I should switch to a higher concentration of Vit. C after I finish my current bottle. Should I buy the Serum 15/20 or the Phoretin CF serum? I'm really worried about acne. Pls advise according to my skin type! The product is expensive but I believe also effective and I'm willing to pay for them to preempt more expensive treatment in the future to treat sun damaged skin! August 20, 2012
