Research Summary
In recent years, interest in the health effects of natural antioxidants has increased due to their safety and applicability in cosmetic formulation. Nevertheless, the efficacy of natural antioxidants in vivo is less documented than their prooxidant properties in vivo.
Plant extracts rich in vitamins, flavonoids, and phenolic compounds can induce oxidative damage by reacting with various biomolecules while also providing antioxidant properties. Because the biological activities of natural antioxidants differ, their effectiveness for slowing the aging process remains unclear.
This review article focuses on the use of natural antioxidants in skincare, the possible mechanisms underlying their desired effect, and recent applications in skincare formulation, along with their limitations.
Keywords: natural antioxidants; vitamins; flavonoids; polyphenols; plant extracts
