What is the function of antioxidants in skincare?

Antioxidants play a crucial role in skincare primarily by protecting the skin from free radical damage. Free radicals are unstable molecules that can cause oxidative stress, leading to premature aging, inflammation, and various skin issues. Antioxidants neutralize these harmful free radicals, effectively reducing their potential damage to the skin cells. This protective mechanism helps maintain healthy skin and supports the overall appearance of youthfulness and vitality.

While some skincare ingredients may provide moisture, brighten the skin, or exfoliate dead skin cells, these functions are not the primary purpose of antioxidants. Moisturizers, for example, contain humectants or emollients to hydrate the skin, brightening agents like vitamin C can enhance skin radiance, and exfoliants (like alpha and beta hydroxy acids) are specifically used to remove dead skin cells. Antioxidants, however, are specifically aimed at mitigating the effects of environmental stressors, making them essential for a robust skincare regimen that prioritizes skin health.
