Tattoo Girl

Henna tattoos (Mehndi) and silver nitrate stains that appear when exposed to ultraviolet light can take up to two weeks to fade from the skin. Temporary airbrush tattoos (TATs) are applied by covering the skin with a stencil and spraying the skin with ink. In the past, this form of tattoo only lasted about a week. With the newest inks, tattoos can reasonably last for up to two weeks.
