Body Art Girl Painting

The same precautions that apply to cosmetics should be observed. If the skin shows any sign of allergy from a paint its use should immediately be ceased. Moreover, it should not be applied onto open wounds, nor should it be applied too close to the eyes. It is not advisable to use paints or products which have not been formulated for use on the body as these can result in serious allergic reactions.
As for Mehndi, natural brown henna dyes are safe to use when mixed with ingredients such as lemon juice. However, a commonly marketed product called "black henna", is not safe to use because the product has been made by mixing natural henna with synthetic black dyes containing PPD, which can cause serious skin allergies, and should be avoided due to the substantial risk of serious injury. Another option is Jagua, a dark indigo plant based dye that is safe to use on the skin and is approved for cosmetic use in the EU.
