For adults (grown-ups), trehalose is generally safe to use on the skin. It’s a sugar used to help moisturize and stabilize products and has very low safety concerns in review reports.
Use products that list trehalose normally on the label. If you want extra caution, try a small patch test on your inner forearm first. Follow the product’s directions and avoid using on broken or heavily damaged skin. Keep products away from children and do not eat them.
Although overall concerns are low, some safety reviews and industry guidance recommend limits on how much to use and on product purity (source: government review and industry safety review). Stop use and see a doctor if you get redness, itching, swelling, or other skin irritation. Avoid putting cosmetic products in a baby’s mouth or on broken skin.
