Tattoo removal is most commonly performed using lasers that break down the ink particles in the tattoo. The process can significantly lighten or almost completely remove the tattoo ink. Different wavelengths of the laser treat different colors of ink. When the ink particles absorb the light from the laser, they break up into tiny fragments. These fragments are then absorbed and removed by your body's own process. This process generally takes a few weeks.
Patients usually require 8- 12 monthly treatment sessions until the tattoo ink is completely removed. The determining factors for the number of treatments needed include size, location, depth, and color of the tattoo. Some colors respond better to laser treatment than others. Treatment sessions may range from 10 to 30 minutes depending on the size of the tattoo.
