Is papain suitable for sensitive skin?

While often considered a gentler exfoliant than some chemical acids, papain can still cause irritation, especially in higher concentrations or with frequent use. Patch testing is recommended for sensitive skin.

How often can I use products with papain?

The frequency of use depends on the product's concentration and your skin's tolerance. It's generally advisable to start with infrequent use (1-2 times per week) and gradually increase if your skin responds well.

Papain

Papain is a proteolytic enzyme derived from the papaya fruit. It works by breaking down proteins, which can help to exfoliate the skin by dissolving dead skin cells. In hair care, it can help to clarify the scalp and hair.
