For infants (0–6 months), trehalose is generally very low risk. It’s a sugar used to hydrate skin and official reviews say it is not expected to be toxic and has low concern for cancer or allergies. Because newborn skin is delicate, we still recommend being careful.
Use only products made for babies or labeled for infant skin. Before spreading on larger areas, try a small patch on the inner forearm and wait 24–48 hours to watch for a reaction. Don't apply to broken or raw skin, and avoid the eyes and mouth. If your baby has very sensitive skin, eczema, was born prematurely, or you are unsure, ask your pediatrician before use.
Watch for redness, bumps, swelling, itching, or any new irritation and stop use if these happen. Note that some industry safety reviews and product-certification programs require manufacturers to document how an ingredient is used safely (source: Cosmetic Ingredient Review and Environment Canada). Also avoid using unknown concentrated forms of the ingredient; prefer finished products formulated and tested for babies.
