ℹ️General Overview

For adults, protease is usually low risk but can cause skin allergies or irritation in some people. Most adults can use products with this ingredient safely, but people with sensitive skin or a history of enzyme allergies should be careful.

✅What to Do

If you're an adult and want to use a product with protease: do a small patch test on your inner forearm and wait 24–48 hours before using widely; avoid using it on broken or inflamed skin; stop use if you notice redness, swelling, itching, or hives; choose products from brands that disclose ingredient concentrations or note any use restrictions.

⚠️Warnings

There is strong evidence from peer-reviewed studies that protease can act as an allergen for some people — watch for signs like redness, itching, swelling, or hives. The U.S. Food and Drug Administration notes limited safe uses in food, and some product verification programs restrict this ingredient unless manufacturers provide extra safety information. If you have a known enzyme allergy, do not use topical products with protease. If a reaction occurs, rinse the area and seek medical advice.

Safety Risk Labels

This ingredient has the following documented risks:

Immune system: Peer-reviewed studies show this protease acts as a human allergen and can trigger immune reactions. That means some people — including children with sensitive skin — could have allergic responses after using products that contain it.
Irritant: Because the ingredient can cause allergic reactions in people, it can also lead to skin redness, itching, or rashes when applied to the skin. This risk is supported by peer-reviewed literature reporting strong evidence of human allergen effects.
Eczema: Allergic or immune reactions to this protease can trigger or make eczema and similar skin conditions worse. Peer-reviewed sources note strong allergen evidence, which makes flare-ups more likely for children with eczema-prone skin.
