Overview
Vitamin C + Alpha Hydroxy Acid is a topical skincare combination that merges the antioxidant and collagen-stimulating properties of vitamin C (commonly in the form of L-ascorbic acid) with the exfoliating effects of alpha hydroxy acids (AHAs), such as glycolic or lactic acids. Vitamin C neutralizes free radicals, stimulates collagen production, reduces melanin synthesis to brighten skin tone, and strengthens the skin barrier. AHAs exfoliate by loosening bonds between dead skin cells on the surface layer, increasing cell turnover and improving texture. When combined in a single product or regimen—such as SkinCeuticals' "C + AHA" serum—this duo provides both environmental protection (antioxidant action) and chemical exfoliation for improved radiance, reduced fine lines/wrinkles, minimized hyperpigmentation, clearer pores, and enhanced absorption of active ingredients[3][1][4]. The combination is especially effective for photoaged or unevenly pigmented skin but may increase sensitivity; gradual introduction is recommended.
