Ascorbic Acid (Vitamin C)
Ascorbic Acid
Ascorbic acid is the pure, active form of vitamin C and the gold standard for topical vitamin C efficacy. It is a potent antioxidant that neutralises free radicals, brightens hyperpigmentation by inhibiting tyrosinase, and stimulates collagen synthesis. It is unstable and degrades with light and oxygen, requiring careful formulation and packaging.
