This two-in-one antioxidant treatment works by two different mechanisms to help improve the appearance of aging skin both inside and out. Below the surface, a 15% concentration of pure L-Ascorbic Acid helps protect against damaging UVA/UVB rays, prevent premature signs of aging, and stimulate collagen production. On the surface, a 10% concentration of Hydroxy Acids exfoliates to smooth the skin and create a more youthful appearance. C+AHA incorporates both Glycolic Acid and Lactic Acid to slough off the rough outer layer of the skin, revealing newer, youthful skin under the surface.

Benefits:

A powerful antioxidant that reduces the appearance of fine lines and wrinkles, neutralizes free radicals, provides photoprotection, and stimulates collagen synthesis.
Proven delivery of L-Ascorbic Acid to the skin in concentrations proven to be effective.
Exfoliates, removing dry, dull surface cells to reveal the youthful skin below.

Directions For Use:
Once in the morning after cleansing, apply 4-5 drops to a dry face, neck, and chest. Follow with SkinCeuticals Hydrating B5 Gel and a SkinCeuticals moisturizer and sun block.

Note: L-ascorbic acid will oxidize and darken with time, but will remain effective. May cause a slight tingling sensation.
