Skin Test
All the products that Body Art By Erin uses on your skin have been proven safe for use on the skin by the FDA.
Having said this, there are people out there that have allergic reactions even to things that are intended for use on the skin. Usually, they know who they are.
Body Art By Erin will suggest to their customers that anyone with a known sensitivity to skin products have a skin test done prior to having their body art performed.
This entails having a spot test of paint/glitter/glue (whichever applies) done on their body about a half hour before they sit back in the chair to have their body art applied. Obviously if there is a negative reaction we would have to abstain from painting this individual.
