Functions

Antioxidant

Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.

Preservative

Keeps your product from growing bacteria, mold, or yeast. Without these, that jar of cream becomes a petri dish in about a week.

Anti-Aging

Targets fine lines, wrinkles, or loss of firmness. Works by boosting collagen, speeding cell turnover, or both.

Skin Protecting

Helps rebuild and strengthen your skin barrier — the invisible shield that keeps moisture in and irritants out. Essential after over-exfoliating or harsh weather.

Neutralizes Free Radicals

Traditional Use

Synthesized in the 1930s as a stabilized form of erythorbic acid (a derivative of vitamin C). Developed as a food and cosmetic preservative and antioxidant to prevent oxidation and discoloration.
