The main active ingredient in the MANDELAC line is Mandelic Acid. Its an alpha-hydroxy acid with a larger molecule than glycolic acid, so its slow penetration doesnt cause irritation, making it especially suitable for sensitive skin.

Apply 4 drops of the product to your hand and massage into the areas to be treated before your usual treatment. All skin types. Morning and night. Mandelic acid, apple stem cells, Morus alba white mulberry, chlorhexidine, aloe vera, hyaluronic acid.
