For adults, aspartic acid is very low risk. It’s a common amino acid used to help condition skin and is not linked to serious health problems in normal topical use.
Use products that list aspartic acid as an ingredient as directed. If you have sensitive skin, do a small patch test on your inner arm and wait 24–48 hours. If your product is from a brand that carries a verification or certification label, know that some programs ask manufacturers to document safe use before including this ingredient.
Stop use and talk to a doctor if you get an allergic reaction like redness, itching, swelling, or a rash. Although overall risk is low, manufacturers and reviewers note that companies sometimes set limits or require documentation for certain ingredients (source: industry reviewers / cosmetic safety reviewers). Government reviews also list it as safe for limited uses (source: U.S. food safety agency and Environment Canada). If you are pregnant, breastfeeding, or have severe skin conditions, check with your healthcare provider before trying new products.
