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
Vitamin C was identified in the 1930s; sodium ascorbate is a stable, water-soluble form developed in the mid-20th century as an antioxidant ingredient in skincare. Used to provide vitamin C's brightening and anti-aging benefits in cosmetic formulations.
