The Lotion P50 1970 is the original formula of the cult favorite toning lotion. The unique combination of Phenol, AHA and BHA work together to exfoliate the skin. This formula is perfect for mature skin or keratinized skin conditions (sensitive Skin Instants® should use a more gentle formula like Lotion P50W or Lotion P50 PIGM 400 for optimal results). Instantly regulate sebum production, restore moisture and maintain the skin's natural pH levels. Reveal radiant and smooth skin!
