Danger Score: 1 (Lower is safer)

Quick Answer: Hydrolyzed Casein is generally considered safe for adults when used in topical products. Adults generally have higher tolerance.

ℹ️General Overview

For adults: hydrolyzed casein is generally safe to use on the skin. It is a milk protein used to soften and condition skin and is not expected to cause harm for most people.

✅What to Do

If you are an adult, check the product label and follow instructions. Do a small patch test on your inner arm and wait 24 hours if you have sensitive skin. If you have a known milk allergy, avoid products that list milk-derived ingredients or ask your doctor before use. Do not apply to open wounds or broken skin.

⚠️Warnings

Watch for redness, itching, swelling, or hives after use — these are signs of an allergic reaction and you should stop use and see a doctor if they occur. Regulatory reviews (Environment Canada and the Cosmetic Ingredient Review) note it is not expected to be toxic but that some products may be restricted unless manufacturers provide safety information. If you have a milk allergy or very sensitive skin, take extra care and consult a healthcare professional.
