Temporary tattoos are not true tattoos; rather, they are a type of body sticker, similar
to a decal. They are generally applied to the skin using water to temporarily transfer
the design to the surface of the skin.
Temporary tattoos are waterproof, but can be removed with oil-based creams, and are intended to last only a few days.
Other forms of temporary tattoos are henna tattoos, also known as mehndi, and the marks made by the stains of silver nitrate on the skin when exposed to ultraviolet light. Both methods, silver nitrate and henna, can take up to two weeks to fade.
Airbrush tattoos are another popular form of temporary tattoos. This process involves using a stencil design and spraying paint through the stencil onto the skin. This form of tattoo lasts approximately a week and is said to be the more realistic type available today.
