Genistein

Genistein is a natural isoflavone derived from soya that is increasingly used in UK skincare for its antioxidant and skin-brightening properties. It is popular in anti-ageing formulas because it helps protect against environmental damage while supporting a firmer, more even-looking complexion. Shoppers often find it in serums, creams and masks aimed at mature or dull skin.

How it works in skincare

In cosmetics genistein functions as a potent antioxidant that helps neutralise free radicals generated by UV exposure and pollution. It also supports the appearance of firmer skin by helping to maintain healthy collagen levels and can improve the look of uneven skin tone and dullness. Its gentle nature makes it a useful addition to both day and night products where a smoother, brighter and more resilient complexion is desired.
