Laser can treat port wine stain, nevus of Ota and other diseases. It is a new method to treat skin diseases. Compared with previous surgery and other treatment methods, it can achieve a magical effect without leaving any traces. Laser treatment uses short pulse laser. Many beauty lovers are curious. What skin diseases can laser research treat?
At present, there are three main categories of skin diseases that can be treated by laser:
Hyperpigmentation skin diseases, such as nevus of Ota, freckle, hairy nevus, freckle like nevus, etc. The target tissue of laser is melanin in melanocytes. Melanin absorbs laser and destroys melanocytes to achieve the purpose of treatment.
Capillary skin diseases, such as nevus erythematosus and telangiectasia, the target tissue of laser is hemoglobin. Hemoglobin can damage blood vessels after absorbing laser. Pulsed dye laser has a good therapeutic effect on these diseases.
Superficial benign tumors, such as syringoma, hair epithelioma, etc. The moisture content of human skin is more than 70%. With water as the “target”, through its gasification and carbonization after absorbing laser, the purpose of removing diseased tissues can be achieved. Pulsed carbon dioxide laser and erbium laser are commonly used.
Laser treatment is not a panacea. It has no therapeutic effect on allergic skin diseases. During laser treatment, the following problems should be paid attention to:
Laser treatment of pigmented or vascular skin diseases is more frequent, usually about five times, and sometimes more. Laser treatment often takes several months to see the curative effect, and sometimes it takes two or three times to see the obvious curative effect. Therefore, the treatment cycle is relatively long, and it takes twoorthree years to completely cure.
Laser treatment can cause temporary abnormal skin pigment, which may be pigmentation or hypopigmentation. The duration varies, and it takes several months or even more than a year to subside.
Although most skin diseases treated by laser will not leave scars, if the lesion is deep or the local care of the beauty seeker is inappropriate after the laser treatment of skin diseases, it may leave ugly scars. Therefore, the beauty seeker needs to pay attention to postoperative care in the treatment of skin diseases by laser.
