Tattoo Removal

Tattoos are no longer permanent. Dermatologists can safely and effectively use Q Switched Nd: YAG LASER to successfully remove unwanted tattoos. During the treatment process the laser beam passes harmlessly through the skin, targeting only the ink resting in a liquid state within. While it is possible to see immediate results, in most cases the fading occurs gradually over the 7–8 week healing period between treatments.

tattoo pigment particle which fragment into smaller pieces. These smaller pieces are then removed by normal body processes. Laser tattoo removal is a successful theory of selective photothermolysis (SPTL). For laser tattoo removal, SPTL for the selective destruction of tattoo pigments depends on four factors

The color of the light must penetrate deep inside the skin

The color of the laser light must be highly absorbed by the tattoo pigment.

The pulse duration of the laser energy should be very short so that the tattoo pigment is heated to fragmentation temperature before its heat should not harm the surrounding skin.

The delivered energy must be sufficient during each laser pulse to heat the pigment to fragmentation. Pigment will not fragment if the energy is low and no removal will take place.
