Ota's nevus is the most common pigmented nevus on the face, and it occupies a large area, which has a great influence on the whole facial image and will also hit people's self-confidence. Now laser therapy can help you get rid of Ota's nevus and regain your confidence. Let's talk about it in detail by Sanay plastic surgery experts. Laser removal of nevus of OTA is generally based on the principle of selective photothermal action. Melanin particles in black spot lesions can selectively absorb laser in a very short time, resulting in high fever, which makes melanin particles explode and disintegrate, and then are slowly cleared and metabolized by phagocytes of human body, so that facial nevus of OTA is gradually removed. The whole treatment process of removing Ota's nevus by laser is very safe, mainly because the laser can selectively eliminate the focus, but the surrounding normal tissues will not be affected, so the treatment is very safe, and the beauty seeker's face will not leave scars after treatment, and the physiological function of the normal body will not be affected. However, beauty seekers need to know that laser removal of Ota's nevus can not be completely removed by one treatment, and it usually takes 2-5 treatments to achieve the next ideal of beauty seekers. Every two treatments also have a certain time interval, and generally the whole course of treatment takes 2-3 months. After laser treatment of nevus of OTA, beauty seekers should do a good job of nursing, and the skin in the treatment area should avoid contact with sunlight. There should be no sunshine and artificial strong light sources indoors for a week, and the stay time under the lights and TV lights should not be too long. After a week, you can gradually increase your daily light intake, which can avoid some side effects.
