Functions

Antioxidant

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

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

A modern synthetic antioxidant developed in the late 20th century specifically for cosmetic preservation and anti-aging formulations, with no traditional historical use.
