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 Conditioning

A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.

Brightening

Fades dark spots, evens out skin tone, or adds radiance. Works by slowing melanin production or speeding up cell turnover.

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 derivative of vitamin C created in the 1980s-1990s as a stable, water-soluble form for cosmetics. Developed to provide vitamin C's antioxidant and collagen-supporting effects while remaining shelf-stable in skincare formulations.
