What is laser beauty?

Laser can produce monochromatic light with high energy and accurate focus, and has certain penetrating power, which can locally produce high heat when it acts on human tissues. Laser cosmetology is to use this characteristic of laser to remove or destroy the target tissue and achieve the purpose of cosmetic treatment. It mainly includes laser cutting and laser skin changing. Laser cutting The biggest advantage of laser cutting is less incision bleeding and clear surgical field of vision. At present, the ultra-pulse laser is used to gather the energy emitted by the laser and release it instantly through a special switch. The powerful energy makes the tissue vaporize quickly, which not only makes the cutting speed fast, but also minimizes the heat conduction around the incision, with little damage to the tissue around the incision. It has been applied to double eyelid surgery, eyelid plastic surgery, facial wrinkle removal and so on, and achieved good results. Laser skin changing Laser skin changing uses laser grinding technology. Its principle is to change the focusing characteristics of laser to make the laser spot become a spot, and then scan the spot with a pattern generator according to a certain pattern, so that the high heat generated by the laser spot can instantly remove the target tissue in the scanning range. The intensity, density, shape and size of each spot are controlled by computer, so as to accurately control the depth of target tissue resection and achieve the purpose of treatment. Laser skin replacement not only overcomes the shortcomings of traditional methods, such as easy bleeding and difficult depth control, but also stimulates the elastic fibers of the skin and makes them shrink. The contraction of elastic fibers can tighten the skin, further promote the disappearance of superficial wrinkles, and the wrinkle removal effect is more obvious. Avoid light before and after laser skin changing, take vitamins properly, and apply medicine to face or change medicine after operation to prevent infection. Pigmentation of skin, which occasionally occurs in skin replacement surgery, is more common in yellow people. The incidence of transient pigmentation is high within three months after operation, and this pigmentation disappears within half a year without recurrence. This situation does not need special treatment, so you should avoid light and use some sunscreen skin care products under the guidance of a doctor. In order to avoid permanent pigmentation, we should pay attention to the selection of surgical indications, try to choose patients with lighter or darker skin color, and use skin replacement with caution for those with skin color between the two. Laser therapy uses laser to treat facial capillary hemangioma and pigmented nevus. The principle is that tissues of different colors have different absorption rates for lasers of different wavelengths. When the diseased part is irradiated by these specific wavelengths of laser, these pigments or hemoglobin are most seriously damaged by laser, while the surrounding normal tissues are slightly damaged. When the damaged pathological tissue is gradually absorbed by the body, the pigment in the lesion or skin is cured. Because the laser still has slight damage to normal tissues, the amount of laser irradiation for each treatment should not be too large, so as to avoid excessive damage and scar formation. It is advisable to adopt the treatment method from shallow to deep. After treatment, the damaged pigment is gradually absorbed. Therefore, there is no need to be eager for success in laser treatment of pigmented skin diseases, and there is no need to worry about it for a short time after treatment.
