Most traces of a tattoo can be removed with a number of techniques, though some degree of scarring is likely to result. The suggested method usually depends on factors like the tattoo's size and location, what dyes were used, and how they were introduced into the skin. When the tattoo is small and in an area that's typically under clothing, excision (ex-SIH-zhun) and closure may be performed. This involves cutting away the tattooed skin and re-closing the wound with stitches. If the tattoo is moderate or large and has several colors, laser removal is generally advised. Before the procedure, the skin may be numbed with a topical anesthetic. Lasers are then selected according to their ability to affect certain colors of pigment and over a series of treatments, the tattoo begins to fade. Neon yellow inks are usually the most resistant. However, some faint design usually persists, no matter what colors were used. Even so, lasers are usually more effective and carry less risk of scarring than older techniques like dermabrasion, in which skin is sanded away.
