For babies aged 6–12 months, trehalose is a very low-risk moisturizing ingredient. It’s a sugar that helps skin stay hydrated and is not known to cause harm in normal topical use.
Use products that are made for infants or labeled for baby skin. Before using a new product, do a small patch test on the inner forearm or thigh and wait 24 hours to check for redness or rash. Apply only small amounts to healthy (not broken) skin and avoid the eyes and inside the mouth. If your baby has very sensitive skin or eczema, check with your pediatrician before trying new products.
Watch for any redness, swelling, itching, or rash and stop use if these appear. Government reviews (Environment Canada) classify trehalose as not expected to be toxic and not persistent in the environment, and an industry safety review (Cosmetic Ingredient Review) notes that manufacturers should control concentration and purity — so prefer reputable baby-formulated products and avoid items from unknown sources. Also be aware that some product certification programs may limit use of an ingredient unless the maker provides supporting safety data.
