Birth Mark Removal, Tattoo Removal and Freckles.
The Q-switched Nd:YAG is the most frequently used laser for permanent Tattoo removal. During treatment, pulses of light from the laser are directed onto the tattoo, breaking up the tattoo pigment. Over the next several weeks the body's macrophages remove the treated pigmented areas. One can specifically treat black (which accounts for more than half of all tattoos), blue and green colour.
