For newborns and infants (0–6 months), arginine is usually low risk. It’s an amino acid found in food and in the body, and reviewers consider it safe at the small amounts used in skin products. Still, baby skin is thin and sensitive, so we take an extra-cautious approach.
Choose products made for babies with short ingredient lists and from reputable brands. Test by putting a tiny amount on a small patch of skin and wait 24 hours. Use only a small amount, avoid getting it in baby’s eyes or mouth, and don’t put it on cuts or red, broken skin. If your baby is premature, has very sensitive skin, or a skin condition, talk with your pediatrician before regular use.
Stop use and contact your pediatrician if you see redness, swelling, rash, or other irritation after using a product with arginine. Public safety notes (from food and health authorities and industry reviewers) say arginine is low concern overall but that safe use depends on proper manufacturing, concentration limits, and purity — so prefer products from trusted manufacturers that follow those guidelines. Avoid use on broken skin and avoid applying near the eyes or mouth.
