The special wavelength of Q-Switched ND:YAG laser can penetrate skin of human body according to the theory of “selective laser decomposing” Q-Switched ND:YAG laser removes pigment by the effect of explosive high energy from laser. Because the pigment particle in objective organization absorbs high energy, so the superficial epidermis will be bounded out of the body at the moment, while the other part of the pigment will spilt into the tiny granules that can be engulfed by macrophages of the body .After the digestion of macrophages, it can be excluded from the lymphatic system of the body. The pigment becomes shallow gradually until disappears totally.
The Q-switched ND:YAG laser absorbed the black, blue with 1064nm frequency and the red, pink, purple, brown with 532 nm frequency of the tattoo or pigmentations removed without damages to normal tissue.

Working Principle of  laser tattoo removal :

Laser technology has greatly improved the ability to treat melanocytic lesions and tattoos with the rapidly pulsed Q-switch neodymium: yttrium aluminium garnet (Nd: YAG) laser. The laser treatment of pigmented lesions and tattoos are based on principle of selected photothermolysis. The QS laser Systems can successfully lighten or eradicate a variety of benign epidermal and dermal pigmented lesions and tattoos with minimal risk of untoward effects.

Laser pigment removal machine though high energy of laser transient emission, make irradiated pigment particles absorb energy expansion rupture. Most or all of epidermal pigment group split into smaller tiny particles immediately ruled out in vitro. Part of dermal pigment group fragment into body macrophage phagocytic particles that ingest and excrete through the lymphatic system, thereby eliminating pigment. Due to normal tissue on 1064nm laser absorption is very few, maintaining the cell frame complete. No scar formation conditions. Because of the laser pigment removal is no damage to normal tissues, its security guaranteed maximum customer without complications from postoperative.

Gradually the pigment becomes lighter and lighter till disappearing. Gradually the pigment becomes lighter and ligher.
