Lactic acid

In cosmetics, lactic acid regulates the stratum corneum of the epidermis, by interacting with keratin, and has a slight exfoliating effect: the stratum corneum is more thinner and more flexible, which is desirable in the event of impure skin, acne, psoriasis and keratinization disorders. In addition, lactic acid acts as a humectant and pH regulator, helping to prevent the growth of other microorganisms harmful to the skin.
