ℹ️General Overview

For adults and teens: papain is usually safe for use on normal skin but can irritate the skin, eyes, or lungs and can cause allergic reactions in some people. People with sensitive skin, eczema, or breathing problems should be more careful.

✅What to Do

Do a small patch test on the inside of your forearm and wait 24 hours before using more widely. Start with products used for short times and less often. Don't use on broken, raw, or sunburned skin. If the product is a powder or can become airborne, avoid breathing it in. Keep away from eyes. If you notice redness, itching, swelling, hives, eye pain, or any breathing trouble, stop use and see a doctor.

Safety Risk Labels

This ingredient has the following documented risks:

Irritant: Papain is classified under EU GHS hazard codes as an irritant to skin, eyes, and lungs, and the ingredient record flags a high concern for irritation. This means it can cause skin redness, stinging or rashes, watery or sore eyes, and breathing irritation on contact.
Immune system: There is moderate evidence that papain can trigger immune or allergic reactions. A review in the U.S. National Library of Medicine notes immune/ allergy concerns, and occupational health experts (AOEC) report strong evidence that papain can act as a human immune and respiratory allergen. This can cause hives, swelling, or other allergic responses in some people.
Asthma: Papain is identified as a respiratory toxicant/allergen and is listed as a lung irritant by occupational health sources and EU GHS. Because of this, it can worsen breathing problems or trigger asthma attacks in sensitive children.
Environmental: An environmental agency (Environment Canada) lists papain as an uncertain environmental toxin. That means its effects on wildlife or ecosystems are not well known and could be harmful, so there is an environmental concern.
