For adults, malic acid in skincare is usually safe when used in the amounts found in regular products. The main risk is irritation (redness, stinging, or burning), not long-term illness.
Use products that list malic acid at low concentrations or that are made for everyday skin (not ‘raw’ acid solutions). Do a small patch test on your inner forearm first and wait 24 hours. If you have sensitive skin, rosacea, eczema, or broken skin, avoid products with malic acid or choose ones specifically made for sensitive skin. Rinse eyes right away if the product gets in them.
Watch for stinging, burning, redness, or swelling — irritation is the main concern (based on regulatory and industry safety reviews, including Health Canada and the Cosmetic Ingredient Review panel). Also be aware that some countries place limits on how malic acid can be used in cosmetics, so avoid home-made or very concentrated acid products.
