Laser cosmetic surgery is a new cosmetic method that has emerged in recent years. Laser cosmetic surgery has the following indications: 1, the treatment of pigmented moles (black mole, green mole, red mole) and warts (common warts, filiform warts, infectious molluscum contagiosum) is very effective, generally can be cured at once. 2.It can treat the bright red nevus (capillary hemangioma). Since the effect of large area of bright red nevus using implant or simple excision and pulling together suture is not satisfactory, the treatment with laser can cure or improve. 3.Laser can remove wrinkles. Laser wrinkle removal is mainly applicable to those with shallow wrinkles, and it has the best effect on middle-aged women and those with good skin elasticity. More wrinkles and deeper should not do laser treatment, but should do wrinkle surgery to tighten and remove the excess skin. 4, argon laser can treat stubborn skin ulcers, palsy bumps. Why can laser have such amazing function? Because the laser beam has a high degree of directionality, a high density and coherence, it can be gathered to a very small treatment area, and thus its action site is limited, will not cause damage to surrounding tissues and skin appendages (hair follicles, sebaceous glands, etc.); its penetration depth can be controlled by the input power, as long as the appropriate mastery, will not appear in the local concave scars. There are different types of lasers with different principles of action. The method of laser cosmetic surgery is not complicated. If a mole is removed with a laser, the power of the laser can be selected according to the thickness of the mole, and the beam is directed at the mole, and the lesion will necrotize, scab and fall off. When removing small moles, there is only a local burning pain. For larger moles, a small amount of local anesthetic can be injected underneath the mole before removing the mole. The emerging skin beauty laser uses yttrium neodymium garnet solid-state laser technology instead of the traditional dye laser, which can produce a variety of laser wavelengths. Treatment includes birthmarks, nevus of Ota, dark age spots, freckles, tattoos, vivid nevus, and various erythematous nevi and vascular lesions. There are no various side effects of general laser clinical application, no scar, safe and painless, no after-effects, which is a more ideal method for laser cosmetic treatment. Using laser to treat facial capillary hemangioma, pigmented nevus, etc. The principle is that different color tissues have different absorption rates of different wavelengths of laser light. When the lesions are irradiated with these specific wavelengths of laser light, these pigments or hemoglobin are most heavily damaged by the laser light, while the surrounding normal tissues are slightly damaged, and when the damaged lesions are gradually absorbed by the body, the disease or the pigment in the skin is cured. Since the laser still has mild damage to normal tissues, the amount of laser irradiation should not be too large for each treatment, and it is advisable to adopt the method of treating from shallow to deep in stages. After treatment, the damaged pigment is gradually absorbed, so the use of laser treatment of skin pigmentation diseases can not be rushed, and there is no need to rush after treatment does not appear obvious effect. In addition, there are a few reminders: 1, beauty laser is not an ordinary laser, is able to make everyone beautiful laser, after this treatment will not leave any scar, also no adverse sequelae. 2, our dermatology department of these instruments is a real treasure, are the latest products imported from abroad, you know the price difference between domestic and imported is more than 10 times, the effect of the difference can also be imagined.
