C+AHA is a two-in-one antioxidant treatment that 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.

• After cleansing, apply 4-5 drops to a dry face, neck and chest. Follow with SkinCeuticals Hydrating B5 Gel and a SkinCeuticals moisturizer and sunscreen. May be used on hands. For additional treatment.
