The main activity of the MANDELAC line is Mandelic Acid. It is an Alpha-hydroxy Acid whose molecule is larger than glycolic, so its slow penetration does not cause irritation, making it especially suitable for sensitive skin. It is encapsulated in liposomes that have anti-aging, sebum-regulating, and depigmenting properties. It is also characterized by antimicrobial activity, which is why it is especially indicated for acne-prone skin.
