This two-in-one antioxidant treatment features 15% pure vitamin C to neutralize free radicals and 10% hydroxy acids to exfoliate and smooth the skin. Skin is protected from environmental damage and more youthful skin is revealed.
Formulated according to the Duke Antioxidant Patent, this serum delivers a 15% concentration of L-ascorbic acid that can be effectively absorbed by the skin.
L-ascorbic acid has a reservoir effect, which means it can’t be washed off or rubbed off for a minimum of 72 hours.
In the morning after cleansing, apply 4-5 drops to a dry face, neck and chest. Can also be used on the backs of the hands.
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.
