Product Details

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-, fragrance-, alcohol-, and dye-free
  • Ideal for normal, combination, and oily skin types

How To Use

Skinceuticals

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.

  • Science & Proof

    • Science

    This daytime antioxidant serum blends the power of pure vitamin C (l-ascorbic acid) with a combination of 10% glycolic and lactic hydroxy acids at a pH that maintains their efficacy on skin. It is formulated under the Duke Antioxidant patent. Vitamin C is a highly-potent antioxidant that is, by its structure, difficult to effectively deliver on skin The Duke Antioxidant patent describes the formulation parameters required for effective delivery of vitamin C to skin: 1) pure l-ascorbic acid (vitamin C); 2) an acidic pH within the 2.0-3.5 pH range and; 3) a concentration between 10%-20%. SkinCeuticals is the only brand to formulate antioxidants according to these parameters.
