For adults (men and women), arginine PCA is generally safe to use on the skin. It's used to help skin hold moisture and is not known to cause serious health problems in normal topical use.
Use products that list arginine PCA as directed. If you have sensitive skin, test the product on a small patch (inside forearm) and wait 24 hours. Avoid putting it on open cuts or sore skin. If you are pregnant or breastfeeding and worried, talk with your healthcare provider, but the ingredient is not linked to significant risks in the available safety listing.
Stop use and see a doctor if you get redness, itching, swelling, or any rash after using a product with arginine PCA. Keep skincare products out of reach of children and do not swallow them. The ingredient safety listing notes only low-level concerns for cancer, allergies and reproductive effects, so there is no strong evidence of harm for adults at normal topical use, but watch for allergic reactions and avoid use on broken skin.
