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! Best Skincare Brand and Best Longstanding Brand 2017 as voted for by SkinStore customers.**
Aqua / Water / Eau, Ascorbic Acid, Triethanolamine, Glycolic Acid, Propylene Glycol, Glycerin, Citric Acid, Lactic Acid, Phenoxyethanol, Zinc Sulfate, Disodium Edta, Sodium Hyaluronate.

stinging/itchy
Previously used C+E Ferulic version like it but a bit rich for my combo/sensitive skin, thought this would be a better fit, boy~ was I wrong. it was stinging and itchy wherever I applied, tried a handful of times in a smaller area and the problem persisted, I have to give up and requested a return, a few messages back&ford exchanged no fellow up, I had to toss it, what a shame.
Great morning anti aging serum
Reduces fine lines, also gently exfoliates with out flaking in day, gives skin a glow. If you want something that is not oily, go with this
SAVED MY SKIN!!!
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!
GREAT !!
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.
Prone to breakouts
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.
noticable results
I used this product for 6 months and will continue to do so. I noticed my skin looking more youthful and toned.
