Trehalose is a sugar used to moisturize skin. For toddlers and preschoolers (ages 2–5) it is considered very low risk when used on the skin.
When using a product with trehalose on a 2–5 year old: do a small patch test first on the arm, avoid applying to cuts or sore skin, keep the product away from the child’s eyes and mouth, and stop use if you see redness or a rash.
There are no major safety flags from government reviews (Environment Canada) or industry reviewers, but some industry guidance recommends limits on concentrations or attention to purity in product formulations (Cosmetic Ingredient Review). If you notice skin irritation, swelling, blisters, or any worrying reaction, stop use and contact your pediatrician. Avoid letting young children ingest concentrated product.
