Laser can produce high-energy, focused monochromatic light with certain penetration, and can produce high heat locally when acting on human tissue. Laser beauty is to use this feature of laser to remove or destroy the target tissue to achieve the purpose of beauty 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. The super pulse laser currently used gathers the energy emitted by the laser and releases the energy in an instant through a special switch. The powerful energy vaporizes the tissue rapidly, which not only cuts quickly, but also minimizes the heat conduction around the incision and causes minimal damage to the tissue around the incision. It has been used in double eyelid surgery, pouch plastic surgery, facial wrinkle removal and other aspects, and achieved good results.
Laser skin changing laser skin changing uses laser grinding technology. Its principle is to change the focusing characteristics of the laser to turn the laser point into a spot, and then use the pattern generator to scan the spot according to a certain pattern, so that the high heat generated by the laser spot in an instant can remove the target tissue within the scanning range. The intensity and density of each spot, the shape and size of the scanning image are controlled by the computer, so as to accurately control the depth of removing the target tissue and achieve the purpose of treatment. Laser skin changing not only overcomes the shortcomings of traditional methods such as easy bleeding and difficult depth control, but also stimulates the skin elastic fiber and makes it 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 replacement, take vitamin drugs appropriately, and use drugs or change dressing on the face after laser skin replacement to prevent infection. Skin pigmentation, which occasionally occurs during skin replacement, is more common in yellow people. The incidence of transient pigmentation was high within three months after operation. This pigmentation mostly disappeared within half a year and did not recur. In this case, there is no need for special treatment. Avoid light and use some sunscreen and skin care products under the guidance of doctors. In order to avoid permanent pigmentation, attention should be paid to the selection of surgical indications. Patients with light or deep skin color should be selected as far as possible, and those with skin color between the two should be careful with skin replacement.
Laser treatment uses laser to treat facial capillary hemangioma, pigmented nevus and so on. The principle is that different colored tissues have different laser absorption rates of different wavelengths. When these specific wavelengths of laser are used to irradiate the diseased parts, these pigments or hemoglobin are most damaged by the laser, while the surrounding normal tissues are slightly damaged. When the damaged diseased tissues are gradually absorbed by the body, the pigment in the disease or skin will be cured. Since the laser still has slight damage to normal tissue, the laser irradiation amount of each treatment should not be too large to avoid excessive damage and scar formation. The method of graded treatment from shallow to deep should be adopted. After treatment, the damaged pigment is gradually absorbed. Therefore, the use of laser in the treatment of skin pigmented diseases can not be anxious. There is no effect in a short time after treatment, and there is no need to worry.
