Lattice laser is named because it produces many micro-therapeutic holes in skin tissue during irradiation. Dot-matrix laser is a brand-new technical expression and a new treatment method between invasive and non-invasive, which has broad prospects in the fields of beauty and treatment, skin and plastic surgery. As foreign experts commented, the new generation of dot matrix laser is another milestone technology after botulinum toxin injection. At present, the treatment effect of dot matrix laser is very good, and the factors affecting the treatment effect are mainly related to the pattern, density, micropore size and micropore depth of dot matrix laser, so it is necessary to carry out dot matrix treatment in regular medical institutions. Wang Guihua medical beauty institutions have invested heavily in introducing American luxury star dot matrix laser, which can completely achieve the beauty effect of giving me six days and returning you six years. Dot matrix technology can be completely applied to Asian people, and there are no serious diseases such as pigmentation, discoloration, erythema and scar inflammation. Many hospitals in China also use this high-end technology. And it has been widely recognized by consumers and doctors, and the curative effect is better than we expected in advance. Judging from the current curative effect of dot matrix laser, it has little to do with race, which means that the curative effect is good for both white and yellow people. However, different skin colors have different reactions to laser, which may lead to different clinical manifestations. Operators should have a correct understanding of this, and at the same time should clearly inform consumers, and guide them to cooperate with doctors to do a good job of preoperative and postoperative preparation and nursing.
