ℹ️General Overview

For children aged 2-5 years (toddlers, young children): this plant root extract is generally low risk for use on the skin when it is part of a regular skin product. There is limited specific testing in young children, so we stay cautious.

What to Do

Before using a new product with this ingredient on a child, do a small patch test on the inner forearm or behind the ear and wait 24 hours. Use products made for children when possible. Apply only to healthy, unbroken skin, avoid the eyes and mouth, and start with a small amount. Keep products out of reach to prevent swallowing.

⚠️Warnings

Stop use and rinse the area if you see redness, swelling, itching, or any rash. Seek medical help if your child has trouble breathing or a severe reaction. The provided safety listing notes low-level concerns for cancer, allergies, and developmental effects, but these are rated low; the main practical risk for children is skin irritation or allergy. If your child has known plant or skin allergies, avoid use and check with your pediatrician.
