Laser can remove pigment using the high energy emitted instantly from the laser with special wavelength (1064nm or 532nm). The pigment absorbs the emitted energy resulting in the expansion and cracking into fragments. Some of cracking pigments (in the shallow epidermis) crack into smaller fragments and are expelled from the human body immediately. However, others (in the basal layers) are phagocytized by the macrophages in the human body and expelled from the human body with the lymphatic system after some time. Therefore, the color of pigments becomes shallow gradually and disappeared finally. The cell maintains in primary state and no scars are formed because normal skin absorbs little light energy emitted from laser with the wavelength of 1064nm or 532nm. The side effect is small and users haven't any trouble in the complication after the treatment owing to no normal tissues destroyed by the laser pigment removal.

(1) Extrinsic pigment of human body: Removal of line eyebrow, embroider eyebrow, line lip, lip line and tattoo.
(2) Endogenous pigment of human body: Removal of ephelis, sunsburn, sweat spots, aging spots, Nevus of Ota and café spots.
(3) Hypersensitive pigment source: pigment irritability is generated from the transplant due to the rejection reaction of human body.
