For adults: glutamic acid used on the skin is generally safe and has a very low hazard rating. It’s commonly used in small amounts in skincare and is not linked to major health risks.
Use products that list ingredients clearly and follow the product directions. If you’ve never used a product with this ingredient, test a small patch of skin first. Stop use and rinse if you get redness, itching, or irritation. Choose products from reputable brands that follow good manufacturing practices.
Watch for skin irritation or allergic reaction and stop use if this happens. Note: government reviews (Environment Canada) found it not likely to be toxic or build up in the body, and the U.S. food authority (FDA) allows limited safe uses — these are the sources for the low-risk finding. Industry reviewers (Cosmetic Ingredient Review) note there can be recommendations about concentration or purity, and some product verification programs may restrict its use unless manufacturers provide extra documentation. Avoid using on broken or infected skin and avoid contaminated products.
