Papain Enzyme

Papain enzyme is a gentle natural exfoliant derived from papaya that helps remove dead skin cells for a brighter, smoother complexion. Commonly found in exfoliating scrubs, masks and enzyme peels, it offers a milder alternative to harsh physical scrubs or chemical acids. UK shoppers often choose it for its plant-based origin and ability to leave skin feeling fresh and refined.

How it works in skincare

In skincare formulations papain works as a proteolytic enzyme that breaks down the proteins which hold dead skin cells together on the surface of the skin. This allows it to provide a gentle enzymatic exfoliation that reveals smoother, brighter skin without the abrasion of traditional scrubs. It is often included in leave-on masks, rinse-off peels and cleansing products where it helps to clarify the complexion while remaining kind to the skin barrier.
