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
* Pulsed light irradiator
The selective photo-thermal melting is the phenomenon that, for example, when the light whose wavelength is well absorbed into the
melanin pigment is irradiated to the melanin pigment lesion, the increased melanin pigment in the lesion absorbs the light and
generates heat. As the melanin pigment is destroyed by this light and other sections are not relatively reacted to this light, heat is not generated.
Only the melanin pigment is destroyed and the surrounding skin tissue is safe.
