Bromelain
What is Bromelain?
Bromelain is a complex of proteolytic enzymes extracted primarily from the stem of the pineapple plant, Ananas comosus. It belongs to the family of cysteine proteases, known for their ability to hydrolyze peptide bonds in proteins. In cosmetics, bromelain is classified as an enzymatic active ingredient, commonly featured in exfoliating masks, peels, cleansers, and conditioning treatments. Its primary function involves selectively targeting and dissolving the protein-rich matrix of dead skin cells in the stratum corneum, promoting their natural shedding without mechanical abrasion. This action aids in revealing smoother skin texture while helping maintain the skin's barrier through conditioning effects. As a plant-derived component, it aligns with natural and biotech skincare trends, offering biodegradable exfoliation suitable for various formulations.
