For toddlers and preschoolers (2-5 years), sodium ascorbate (a form of vitamin C) is usually low risk when used on healthy, unbroken skin in normal amounts. The main concern is skin allergy — some expert reviews say it can trigger skin reactions.
If you want to use a product with this ingredient on a 2-5 year old: choose products made for children when possible; check the label for concentration and instructions; do a small patch test on the child’s inner forearm and wait 24–48 hours before wider use; avoid applying it to irritated, broken, or inflamed skin; stop use and rinse with water if you see redness, itching, swelling, or a rash; call your pediatrician if a reaction is severe or spreads.
Watch for allergic skin reactions — Cosmetic Ingredient Review (CIR) reports strong evidence that this ingredient can be a skin allergen. Also note that some safety reviews place limits on concentration or product types and that there are gaps in safety data on exact safe concentrations for topical use in children (sources: Cosmetic Ingredient Review (CIR); U.S. Food and Drug Administration (FDA); Environment Canada). Avoid products that don’t list how much vitamin C they contain or that give no child-specific directions.
