Laser scar removal here laser refers to a variety of photoelectricity, there are lasers, photons, radio frequency, etc. Laser treatment of scarring, mainly through the scar epidermal micro-exfoliation (or grinding) and the stimulation of the growth of the skin's deep collagen to achieve the softening of the scar, to improve the flatness, so that the pigment is redistributed and so on the role of laser treatment of scars, the basic principle of laser treatment of scars is the selective thermal effect of the skin tissue of the main color base of hemoglobin, The main principle of laser treatment for scars is to selectively heat the main color base of the skin tissue, hemoglobin, melanin, water molecules for hemoglobin pulsed dye laser, photonics, 532nm-1064nmNd-YAG laser can be closed to the early proliferation of capillaries, inhibit the scar proliferation of the laser for melanin mainly Q-modulated laser, Laser for melanin. Strong>Q-modulated laser, such as Nd-YAG laser, ruby laser and emerald laser for color deposits or dust deposits have a good therapeutic effect, for water molecules more such as CO2 laser, erbium laser, infrared laser, etc., as well as ultrasound, radiofrequency, plasma, etc. This kind of photoelectricity is mainly to produce suitable thermal damage, and The main purpose of this kind of photoelectricity is to produce suitable thermal damage and stimulate the regeneration and repair of tissues.
