SkinCeuticals C + AHA 30 ml | 1 oz

C + AHA is a two-in-one daytime antioxidant serum that works by two different mechanisms to help improve the appearance of skin. Formulated with 15% pure vitamin C (l-ascorbic acid) and a blend of 10% hydroxy acids, neutralizes free radicals and exfoliates skin to promote clear skin and minimize the appearance of blemishes. In addition to providing the benefits of vitamin C, this daytime antioxidant serum reduces the appearance of fine lines and wrinkles as it improves overall skin radiance.


  • Neutralizes damaging free radicals caused by environmental aggressors
  • Exfoliates dry, dull surface cells to help improve the appearance of blemishes and skin texture
  • Paraben-, alocohol-, dye-, fragrance-, silicone-, and gluten-free


How to Use

In the morning after cleansing, apply 4-5 drops to a dry face, neck, and chest. May also be used on the backs of the hands. Finish with a SkinCeuticals broad spectrum sunscreen.

    Terrible on me

    Posted by Natalie on 27th Feb 2023

    I LOVE Skinceuticals products, I would say at least half my medical grade skincare is Skinceuticals but this product is a HUGE MISS. No matter how I applied, how long I waited, ANY moisturizer or sunscreen I applied on top of this balled and gunked up in an awful way. I'm so disappointed because it was so expensive, but it absolutely did not work for me.

    Brianna wasn't kidding when she raved about this! I have been using this for a week now and my skin is looking brighter, my hyperpigmentation is fading, and more pores look so small!! I have used many great vitamin C serums before but nothing has given me these changes to my skin like this!
