When the ND:YAG laser light energy composed of the solid laser medium (ND: YAG) is adjusted to the pulse energy of 1064 nm and 532 nm wavelength and irradiated to the skin, the other chromophore is inhaled according to the wavelength and the laser light energy is converted into thermal energy, and at this moment, most of the effects are shown as a thermal reaction, and on account of the photo-thermal effect, that is, each wavelength of the laser is selectively absorbed into the tissue by utilizing the characteristic that the absorption rates of biological tissues are different with each other, the thermal energy is selectively transmitted only to the portion irradiated with laser, so that the cutting, destruction and removal of tissue can be performed.
ex) *1064nm (Toning specialty, silver) - DPL double toning after skin regeneration and pigment removal
*1064nm (Focus lens, pink) - Removing the blemishes, freckles, age spots, and tattoos
* 532nm (Toning specialty, blue) - Improving the skin tone and tissue, and removing the epidermal pigment
