THE'Mandelic Acid It is an Alpha Hydroxy Acid (AHA) derived from bitter almonds that stands out for its extraordinary exfoliating properties that respect the skin's balance. The particles of this acid are larger than those of more common acids like glycolic and salicylic, allowing for exfoliation without irritating the skin. Mandelic acid is perfectly suited for the gentle cleansing of sensitive skin and is ideal for darker skin types. It penetrates deeply into the skin because it is oil-soluble and has antibacterial properties that promote cell turnover, combats acne issues, and leaves the skin smooth, soft, clean, and radiant without excessive dryness.
