Medium strength 30% acid combination for use in peel protocols for clarifying and lightening. This amazing acid blend features three proven acne and pigmentation fighters. Mandelic acid, an AHA, derived from bitter almonds, has a larger molecule size which is more slowly absorbed for more even application making it a good choice for darker skin types. Its key features are its strong anti-microbial and depigmentation abilities which make it ideal for acneic skin. Salicylic acid, a beta hydroxy acid, is a standard in clarifying treatments because of its keratolytic and anti-inflammatory qualities. Lactic acid is a mild alpha hydroxy acid used on more sensitive skins to remove impurities and gently exfoliate.
