BROMELAIN.

Valuable CAS 9001-00-7 / 37189-34-7 / KERATOLYTIC, SKIN CONDITIONING

A proteolytic enzyme derived from pineapple that provides gentle enzymatic exfoliation by breaking down keratin proteins in the skin's surface layer. This multi-functional ingredient combines effective exfoliation with anti-inflammatory properties, making it suitable for addressing both texture concerns and inflammatory skin conditions. Unlike harsh chemical exfoliants, bromelain offers selective action that targets dead skin cells while preserving healthy tissue.

keratolytic skin conditioning anti-inflammatory enzymatic exfoliant

Science

Functions as a thiol protease that specifically digests keratin proteins within the stratum corneum, enabling controlled enzymatic exfoliation. Simultaneously reduces inflammation by inhibiting NF-κB signaling pathways and decreasing synthesis of inflammatory mediators including prostaglandins and COX-2. Additionally supports wound healing through selective debridement activity and may help address hyperpigmentation by modulating tyrosinase enzyme function.
