How is the Q-switched Ruby Laser different to other tattoo removal lasers?
The Ruby laser produces extremely short pulses of high-energy, red light with a wavelength of 694nm. This light is absorbed strongly by particles of tattoo pigment but not by the surrounding skin. The tattoo pigment particles heat up and break down into smaller particles; these minute particles are targeted by the body’s own immune system and removed. Because the energy is selectively absorbed by the tattoo pigment, surrounding tissues are not usually affected and there is usually no lasting damage to the skin.
