How long do fake tattoes last?

Fake tattoos, such as temporary tattoos, typically last from a few days to a couple of weeks, depending on the type and application method. The longevity can be affected by factors like skin type, exposure to water, and friction from clothing. Some types, like henna or airbrush tattoos, may last longer, up to several weeks, while others may fade more quickly. To maximize their duration, it's best to apply them on clean, dry skin and avoid excessive scrubbing or washing.
