For adults (grown-ups): Proline is a natural amino acid used in creams and lotions and is considered very low risk when used on skin at normal concentrations.
You can use products that list proline in the ingredients the way the product says. If you have sensitive skin, test a small amount on the inside of your forearm first and wait 24 hours. Do not put products on broken or irritated skin. Follow the product label for frequency and amount.
Watch for any new redness, itching, rash, or swelling after use and stop the product if that happens. Some industry reviewers recommend limits on concentration and attention to purity in manufacturing — these are the reasons manufacturers sometimes set their own limits.
