I am fully insured under a policy specifically for face painters and henna artists under Beauty & Bodywork Insurance. I use only high-quality, professional-grade, hypoallergenic materials approved for use on skin. Allergic reactions or serious injuries are extremely unlikely, but if you or your child have a severe skin sensitivity, allergy, or skin condition and you are concerned, it may be better to be safe than sorry.
The face paints, airbrush tattoo ink, and glitter tattoo glue I use are all approved for cosmetic use and safe for skin. The henna and jagua I use are plant-based, all-natural and free of harsh chemicals and dyes. They should not cause any reactions unless you are allergic to the plant-based ingredients. People with a berry allergy should not use jagua.
Removal differs for each material. See more about removal here.
