Tattoo Removal While tattoos are considered permanent, it is possible, to varying degrees, to remove them. Complete removal, however, is often not possible, and the expense and pain of removing them typically will be greater than the expense and pain of applying them. Some jurisdictions will pay for the voluntary removal of gang tattoos. Tattoo removal is most commonly performed using lasers that react with the ink in the tattoo, and break it down. The broken-down ink is then absorbed by the body. This technique often requires many repeated visits to remove even a small tattoo, and may result in permanent scarring. A newer method of removal is by tattooing glycolic acid into the skin with a tattoo machine: the acid pushes the ink to the surface of the skin in the scab, which is later removed. This method purportedly scars less than laser techniques. Glycolic acid is also used for facial peels; when used for tattoo removal, a lower percentage mix is used. Some wearers opt to cover an unwanted tattoo with a new tattoo. This is commonly known as a coverup or cover-up. An artfully done cover-up may render the old tattoo completely invisible, though this will depend largely on the size, style, colours and techniques used on the old tattoo. Some shops and artists use laser removal machines to break down and lighten undesired tattoos to make coverage with a new tattoo easier. Overall, green-based ink is the most difficult to remove. Black ink is most readily broken down by the laser, and unprofessional tattoos done at home are the easiest ones to remove, due to the low quality of ink used, as well as the ineffective manner in which they were applied.
