What it does
It’s an extract of papaya fruit, sold as an enzyme exfoliant. How much papain, papaya’s protein-breaking enzyme, the extract holds isn’t documented. In lab and mouse studies, papain weakened the skin barrier and caused allergy.
The EU’s ingredient database lists it as a skin conditioner, its general term for an ingredient that keeps skin in good condition.European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
