5+ year old children • Skin contact product
For children aged 5 years and up (school-age kids, children, and preteens), this plant extract is usually safe to use on the skin. Safety databases rate it as having very low concern for serious harms. Most children will not have problems, though a few may get mild skin irritation.
Before using a new product on your child’s skin, do a small patch test: put a tiny amount on the inside of the forearm and wait 24–48 hours. If there’s no redness, swelling, or itching, it’s likely okay to use as directed. Use products with this ingredient on intact skin only, follow the product’s instructions, and avoid combining multiple new products at once so you can spot which one causes a reaction.
Watch for redness, itching, swelling, blisters, or any new rash after applying the product — these are signs of skin sensitivity and you should stop use and rinse the area. The ingredient safety records list only low-level concerns for cancer, allergy, and developmental effects, so those are not major risks for topical use in this age group, but if your child has a known plant or botanical allergy, avoid use and consult your pediatrician. If irritation is severe or does not clear, seek medical advice.
