Professional face paint is cosmetic-grade, FDA-compliant for skin use, and designed specifically for sensitive skin. It is water-based and easily removable with soap and water. I also recommend makeup remover or even coconut oil for any stubborn paint. We use body-safe creamy organic henna paste, and biodegradable eco glitter.
However, as a fully insured bodywork artist the face paint manufacture states I cannot paint anyone 3 years old or younger with their paints. And to remain in compliance, I offer stickers and temporary tattoos for younger ones instead of face painting.
