For adults: levulinic acid is generally safe to use on the skin at levels normally found in cosmetics. Reviews from government and scientific bodies show low concern for cancer, allergies, or reproductive harm when used topically as intended.
Choose products from reputable brands and follow the product directions. If you have sensitive skin, do a small patch test (apply a little product to the inside of your forearm and wait 24–48 hours). Stop use and rinse if you get redness, itching, swelling, or any strong irritation. If you are pregnant, breastfeeding, or have serious skin conditions, talk with your healthcare provider if you have concerns.
Avoid applying to broken, raw, or badly irritated skin. Watch for signs of an allergic reaction (persistent redness, swelling, hives). The safety information comes from government and scientific reviews: the U.S. Environmental Protection Agency (cancer conclusion), the U.S. Food and Drug Administration (uses in food), Environment Canada (toxicity and environmental persistence), and the Cosmetic Ingredient Review (guidance on safe concentrations). Also be aware that some product-verification programs restrict this ingredient unless the maker provides additional safety data.
