For school-age children (5 years and up), malic acid in small amounts is usually low risk when used on skin. It can cause irritation to skin and eyes, and some health authorities limit how it can be used in cosmetics.
Use products that list low concentrations or are labeled safe for kids. Avoid high-strength acid products (like strong exfoliating serums) and leave-on treatments with malic acid. Do a small patch test on the inside of the arm for 24 hours before using on the face or large areas. Rinse the area well if a product stings or the child is uncomfortable. If irritation occurs, stop use and consult your pediatrician.
Watch for redness, stinging, burning, flaking, or eye contact — these are signs of irritation (reported by safety reviewers). Health Canada has placed use restrictions on this ingredient in cosmetics, and the Cosmetic Ingredient Review notes strong evidence that it can irritate human skin or eyes. Do NOT use on broken, inflamed, or very sensitive skin. Avoid combining with other strong acids or exfoliants for children.
