For children 5 years and older (kids, older children, tweens and teens), trehalose is considered very low risk when used on the skin. It’s a sugar that helps hold moisture and is not known to cause serious health problems when used in skincare.
Use products that list trehalose normally (moisturizers, lotions, cleansers). If it’s your child’s first time using a product with trehalose, do a small patch test on the inside of the arm and wait 24 hours. Stop use if you see redness, itching, or a rash. Prefer products made for children when possible and follow the product’s directions.
Watch for signs of skin irritation or an allergic reaction (redness, itching, swelling). If these occur, stop use and talk with your child’s pediatrician. Safety assessments cited here come from Environment Canada and the Cosmetic Ingredient Review, and some product‑certifying programs may ask manufacturers to provide extra safety documentation — that requirement is about verification, not evidence of harm.
