For infants (0–6 months) aspartic acid is generally low risk when used in small amounts on skin. It's a normal amino acid and reviewers consider it low concern for cancer, allergy, and reproductive harm. Because newborn skin is very delicate, we still recommend being careful.
Prefer products labeled for babies or newborns. If you consider a product that lists aspartic acid, try it on yourself first. If you decide to try it on your baby, apply a very small amount to a tiny area (inner thigh or forearm) once and watch for 24 hours for any redness, swelling, or rash. Use sparingly, avoid applying to broken, irritated, or eczema-prone skin, and stop use immediately if you see any reaction. If your baby has eczema or very sensitive skin, talk with your pediatrician before use.
Watch for redness, swelling, itching, hives or any new rash after applying a product that contains aspartic acid — stop use and contact your pediatrician if these occur. Some product safety programs restrict use of this ingredient unless manufacturers provide supporting data; check product labels or ask the brand for safety information if you see a "restricted" notice. These cautions are based on information from the U.S. Food and Drug Administration, Environment Canada, and industry safety reviews.
