Cosmate® KA, which contains kojic acid (KA), a natural metabolite produced by fungi that effectively inhibits tyrosinase activity in melanin synthesis. After entering skin cells, kojic acid binds to copper ions and blocks tyrosinase activity. Compared with other whitening agents, kojic acid has excellent inhibitory effect on tyrosinase and is now widely used in various cosmetics. It's specially formulated to treat freckles, age spots and hyperpigmentation, providing an even, radiant complexion. Discover the power of kojic acid in your skin care routine for visibly clearer, brighter skin.
