I read that tattoo removal can be painful, expensive, and time-consuming. Despite the intended permanence of tattoos, various methods are used in attempts to remove them: Laser removal (burning the tattoo away), surgical removal (cutting the tattoo away), dermabrasion (sanding the skin with a wire brush to remove the epidermis and dermis), salabrasion (using a salt solution to soak the tattooed skin), and scarification (removing the tattoo with an acid solution and creating a scar in its place). These methods are expensive and can be painful. “It’s more painful to have a tattoo removed by laser than to get the original tattoo,” says Teen magazine. Also more modern, multicoloured tattoos, especially if they are large, are almost impossible to remove.
