Papain

Also known as Papaya enzyme, Carica papaya enzyme, Papain enzyme

A proteolytic enzyme commonly derived from papaya and used in skincare to help loosen and remove surface dead skin cells through enzymatic exfoliation.

Enzyme exfoliant

What it is

Papain is a protease enzyme associated with papaya. In cosmetic exfoliating formulas it acts on proteins at the skin surface rather than functioning like an alpha- or beta-hydroxy acid.

Common uses and benefits

Papain is used in enzyme powders, masks, and exfoliating treatments to support surface exfoliation and a smoother-looking texture. Published reviews of proteolytic enzymes identify papain among enzymes used for cosmetic exfoliation, while noting that activity and tolerability depend on formulation conditions.

Who may like it

It may appeal to shoppers who want an enzyme-based alternative or complement to acid exfoliation, particularly in rinse-off or customizable powder formulas.

Common formats

  • Papain
  • Papaya enzyme powders
  • Enzyme masks
  • Powder exfoliants
  • Rinse-off treatments

Pairing and use notes

Papain is often paired with soothing ingredients such as allantoin and with clays or gentle cleansing agents in rinse-off exfoliating formulas. Frequency should be adjusted to the finished product and skin tolerance.

Good to know

Proteolytic enzymes can irritate or sensitize some skin. Avoid inhaling dry enzyme powders, avoid broken or irritated skin, and reduce frequency if stinging or persistent redness occurs.
