Mandelic acid is a member of the family of alpha hydroxy acids; its commercial name is revealing of its natural origin, as it is found in bitter almonds (mandel = almond), as well as in apricots and peaches. Mandelic acid normalizes the keratinization process and enhances skin exfoliation. As a result of its macromolecular structure, it has a mild chemical peeling effect, which helps prevent irritations and makes it suitable for all skin types and all phototypes. It hydrates the skin, enhances cellular remodelling and reduces skin discolouration. Its antimicrobial action makes mandelic acid ideal for fighting acne.
