2-5 year old preschoolers • Skin contact product
For children ages 2-5 (toddlers and preschoolers), arnica used on the skin can sometimes cause allergic skin reactions. Overall it is low concern for most problems, but the chance of a skin allergy is real, so be careful.
If you want to use a product with arnica on a 2–5 year old: choose a product made for gentle skin or diluted formulation, do a small patch test on a small area and wait 24–48 hours, don’t put it on open wounds or broken skin, avoid the face, eyes and mouth, use only short-term as directed, and stop immediately if you see redness, itching, swelling, blistering or any other reaction. Talk to your child’s pediatrician before using regularly.
Safety reviewers (Cosmetic Ingredient Review) report strong evidence that arnica can be a skin allergen — watch for rashes, red or itchy skin, swelling or blistering. There are also gaps in safety data for other effects, so avoid regular long-term use on young children and do not apply to broken or irritated skin. If your child has known allergies to plants like ragweed, avoid arnica. For severe reactions (trouble breathing, face/tongue swelling), seek emergency care.
