Modified Jessner Peel

Four acids, four mechanisms, one comprehensive resurfacing treatment. No single-acid peel can match the breadth of correction this formula delivers in a single session. Salicylic Acid clears oil-clogged pores from the inside out — it's the only BHA that's oil-soluble, meaning it can actually penetrate through sebum. Mandelic Acid renews the surface gently enough for darker skin tones without triggering post-inflammatory hyperpigmentation. Glycolic Acid reaches the deepest layers to stimulate collagen production. Azelaic Acid targets both acne bacteria and hyperpigmentation simultaneously. Together, they deliver thorough, even exfoliation that addresses texture, tone, clarity, and firmness in one professional treatment. Bio Jouvance Paris modified the classic Jessner formula to be more effective and less irritating. Professional use only.
