SkinCeuticals C+AHA

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. **Winner!
