For school-age children (5 years and up), sucralose in skin products is generally safe. It doesn’t easily get into the body through the skin and is not linked to major health risks at typical product levels.
Use products that list sucralose on the label and follow product directions. Do a small patch test on your child’s inner forearm before wider use. Keep products out of reach so young children don’t lick or eat them. If your child has very sensitive skin, choose fragrance-free or simplified formulations.
Watch for any skin redness, rash, or irritation after first use, and stop use if these happen. A scientific review (Organohalogen Pollutants and Human Health) notes sucralose can persist and may accumulate in the environment — this is an environmental concern rather than an immediate skin risk. Regulatory and industry reviews (for example, the U.S. food regulator’s decisions on limited food use and the Cosmetic Ingredient Review’s guidance on concentrations and purity) support limited, controlled use — follow manufacturer instructions and avoid off-label high-concentration uses.
