Papain and Bromelain

How it works in skincare

In cosmetics and skincare, papain and bromelain function as proteolytic enzymes that selectively break down the keratin and other proteins that hold dead skin cells together. This allows for a mild, enzymatic exfoliation that reveals fresher skin underneath, while also helping to soften and smooth rough texture. They are commonly found in cleansers, masks, peels and brightening treatments, where they offer a natural alternative to mechanical or acid-based exfoliants.
