This lightweight antioxidant face serum combines 0.2% ferulic acid with 15% pure vitamin C (l-ascorbic acid) for enhanced vitamin C serum benefits. It is formulated under the Duke Antioxidant patent. Vitamin C is a highly-potent antioxidant that by its structure has difficultly being effectively absorbed by skin. The Duke Antioxidant patent outlines the formulation parameters required for effective delivery of vitamin C to skin: 1) pure l-ascorbic acid (vitamin C); 2) an acidic pH within the 2.0-3.5 pH range and; 3) a concentration between 10%-20%. SkinCeuticals is the only brand to formulate antioxidants according to these parameters.

Rated 5 out of 5 by Anonymous from My every day treatment I have very sun sensitive skin. I tan very easily in a short time. I also live in Texas so I ended up with uneven skin tone and freckles and sun spots. I wanted to try out a vitamin C product to help my skin. I actually see the difference in my skin and I've been using this serum for about a year. My uneven skintone looks much more even toned and I dont see any more new sun spots coming up. So happy! I feel good about preventing sun damage to my skin. I wish I've done it earlier.

Rated 5 out of 5 by Supka from glowing smooth skin I have used this product daily for over ten years. People constantly comment on my glowing wrinkle-free skin, even strangers meeting me for the first time. I am 57 years old and I have to think the skin care products I use have something to do with how my face looks. I first tried this product during a facial at Ritz Carlton about 15 years ago. I have sensitive skin prone to breakouts and Skinceuticals is the best product I found for my skin to date.

Rated 5 out of 5 by Pierce from It's a miracle I was given a free 7 day sample. Within 3 or 4 days everyone that knows me asked what I've been doing? because I look great. I can't be without it.
