Papain Enzyme
What is Papain Enzyme?
Papain is a natural proteolytic enzyme extracted from the latex of unripe papaya fruit (Carica papaya). As a cysteine protease, it functions by hydrolyzing peptide bonds in proteins. In cosmetics, it belongs to the enzyme category, commonly featured in exfoliating peels, masks, cleansers, and smoothing treatments. It works by selectively targeting and dissolving the keratin proteins in dead surface skin cells, promoting cell turnover without mechanical abrasion. This enzymatic action helps remove buildup, revealing fresher skin underneath. Formulations often stabilize papain to control its activity, ensuring it remains effective during product use while minimizing potential breakdown of other formulation components.
