One of the most common techniques is laser surgery. Laser tattoo removal removes a tattoo by targeting the ink with bursts of light that will break it up. Once broken up under the skin, the ink will be expressed by the immune system. Laser surgery does not remove tattoos in one sitting, however; large, full color work may take over ten treatments to remove. The long term effects of repeated laser treatments can include serious scarring, which makes this option most effective for small tattoos in dark ink. Laser surgery for tattoos in light inks can be very expensive and require many sittings.
