Ascorbic Acid
Ascorbic acid is the pure, active form of vitamin C used in skincare. It is a powerful antioxidant that helps brighten the complexion and protect skin from environmental damage. Shoppers often seek it in serums for its ability to promote a more radiant, even-toned appearance.
How it works in skincare
In cosmetics and skincare, ascorbic acid functions as a potent antioxidant that neutralises free radicals generated by UV exposure and pollution. It helps inhibit melanin production to visibly brighten skin and supports natural collagen synthesis, contributing to improved firmness and elasticity. Being water-soluble, it is most commonly formulated into lightweight serums and creams where it delivers a fresh, stable burst of vitamin C activity when properly stabilised.
