The lattice laser in our hospital is a new local therapy for treating some skin diseases and wrinkles with CO2 laser. The effect of dot matrix laser is particularly good. Judging from the current effect of dot matrix laser, both white and yellow people have good skin beauty effects. Dot-matrix laser is a new type of CO2 laser local therapy, which uses CO2 laser energy to penetrate under the skin and stimulate the birth of new collagen. Energy is applied in stages, that is, a small amount of thermal damage is separated, so that the normal tissue between thermal damage is not affected.
