Tattoos can be removed with laser treatment, but can leave a degree of shading and scarring on the skin. Between six and eight treatment sessions are usually needed and each can cost several hundred pounds.

Excerpt: There are three basic techniques: cutting away the tattooed skin, dermabrasion (rubbing away the tattooed skin with an abrasive device), or laser removal. The British Association of Dermatologists says several laser sessions may be needed, even for small tattoos. The tattoo shown here was removed via laser; the scar below it was left from dermabrasion removal. Some colour inks are harder to remove than others and repeated visits are required; permanent tattoos may never be gone entirely.
