Dual-action antioxidant/exfoliating serum
C + AHA

30 ml 1 fl oz

A two-in-one, daytime antioxidant and exfoliating serum, C + AHA features 15% pure vitamin C to neutralize free radicals, protect skin from environmental damage, and help prevent premature aging. In addition to its antioxidant benefits, a blend of 10% glycolic and lactic acids helps eliminate dull, dry skin cells to improve the appearance of fine lines, wrinkles, and skin radiance as it refines surface texture and promotes a clearer complexion.

• Exfoliates dry, dull surface cells to help improve the appearance of blemishes and skin texture
• Paraben-, fragrance-, alcohol-, silicon-, gluten-, and dye-free
• Ideal for normal, combination, and oily skin types

Science
This daytime antioxidant serum blends the power of pure vitamin C (l-ascorbic acid) with a combination of 10% glycolic and lactic hydroxy acids at a pH that maintains their efficacy on skin. It is formulated under the Duke Antioxidant patent. Vitamin C is a highly-potent antioxidant that is, by its structure, difficult to effectively deliver 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.

Use
In the morning after cleansing, apply 4-5 drops to a dry face, neck, and chest. May also be used on the backs of the hands. Finish with a SkinCeuticals broad spectrum sunscreen.
