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.


  • 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.

Recommended by my dermatologist about 6 years ago and has saved my skin from breakouts. It has refined the texture of my combination skin and works well as an anti aging agent.AHA is just great for daily exfoliation. Hope SkinCeuticals does not stop this product, as it ihas been a lifesaver. Still worth the price!

I use this everyday with the Simply Clean cleanser. My skin was always very oily before starting this regimen. My visits to have a Microdermabration have been reduced by half. ( I'm 44 and signs of aging came on quick. This makes a big differerence)

Wonderful product!


This is by far the best product on the market. It does tingle slightly, but this should be expected. I've tried the C E Ferulic acid (same brand), but this is works much better. My skin is radiant and smooth - well worth the price.

This serum has eliminated my breakouts and cleans my skin throughout the day. I would recommend this for anyone who breakouts out tremendously and has tried everything on the market. been a user for two years

oxidizes quickly once opened


This product is not only overpriced to begin with, it oxidizes and turns orange and sticky once opened and exposed to oxygen. This reduces the effectivness and feels unpleasant. I used twice a day on face, neck and chest and still did not get through the bottle before it went bad! There are cheaper, better alternatives available.
