This facial serum neutralizes free radical damage that contribute to atmospheric skin aging – environmental damage and premature signs of aging caused by free radicals from UVA/UVB. In addition to antioxidant benefits, this facial serum improves the appearance of fine lines and wrinkles.
- Neutralizes free radicals induced by environmental aggressors

How To Use
In the morning after cleansing, apply 4-5 drops to a dry face, neck, and chest to promote healthy skin. Apply before other skincare products. May be used on the back of the hands. It is normal for vitamin C products to darken after opening due to air and light exposure. The formula will remain effective. Once opened, it is recommended to be used within 3 months of opening.
Complete your regimen with a SkinCeuticals sunscreen. When used together, SkinCeuticals antioxidants and broad spectrum sunscreens provide more comprehensive protection against visible aging caused by environmental aggressors.

Science & Proof

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 on skin. The Duke Antioxidant patent describes 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.

I really wanted to be wow'ed by the product especially for the price. However, I did not find that it was so much more amazing then cheaper alternatives. It is great for all skin types and I know many people who have had great results using this product.

Love this serum, usually apply it after my vitamin c serum in the morning and use after AHA/BHA in the night before going to bed and follow it with a moisturizer . Love the way my skin feels next day, very hydrated and plumped.

I purchased this recently with my normal cleanser to compliment my sun protection regimen. It was not greasy and left my skin feeling smooth and soft. It will be my new buddy to sunscreen to prevent damage on daily basis! Only negative is the price point

Everyone should be using this
I started using Skinceuticals Vitamin C 20% in my 30's, within weeks it corrected my crepey eyes caused by too much sun growing up. I'm in my 50's and my skin still looks like I'm in my 30's with no sun damage. This product should be an important part of everyone's skincare.
