How do the lasers eliminate a tattoo?
Lasers work by producing short pulses of intense, pure, one colour of light that pass through the top layers of the skin to be selectively absorbed by the birthmark’s pigment. This laser energy causes the pigment to fragment microscopically. Some of the pigment comes off with the crust that forms after laser treatment; the body absorbs some of the pigment as it heals, and a small amount of pigment stays invisible in the tissue. We have determined which wavelength of light to use, and how to best direct the laser’s energy to remove a tattoo.
