Laser tattoo removal works by breaking up the pigment colors with a high-intensity laser light beam. Black tattoo pigment absorbs any laser wavelengths, which makes it the easiest to treat. Other colors can only be treated by certain lasers based on the pigment color.
On average most people need 6 to 8 sessions to remove their tattoo. This varies due to factors like the color, pigmentation, size, and how old the tattoo is. For large tattoos, upwards of 10 sessions may be needed.
