Milk protein is generally safe for adults to use on the skin. It is used to moisturize and condition skin and is not expected to cause serious harm. A small number of people may have allergic or irritating reactions.
If you are an adult and want to try a product with milk protein, do a small patch test on the inside of your forearm first and wait 24 hours to check for redness, itching, or swelling. Avoid using it on badly broken or infected skin. If you have a known milk or dairy allergy, talk to your doctor before using products with milk protein. Choose well-made products from reputable brands that list ingredients clearly.
Watch for signs of skin allergy or irritation (redness, itching, rash, swelling). There is limited evidence of allergic reactions (source: U.S. National Library of Medicine). Reviews by government bodies find it not expected to be toxic or an environmental toxin (source: Environment Canada). Industry reviewers note recommendations on concentration and purity—avoid products with unclear sourcing or high, unspecified concentrations (source: Cosmetic Ingredient Review). Stop use and see a doctor if you get a severe reaction.
