Nevus removal by plastic surgery is introduced. Laser Dot mole can remove moles without damaging other normal parts of the skin by using the principle of photothermal separation and the selective characteristics of laser. The principle of laser Dot mole is that laser instruments produce high-intensity beams, because different types of lasers can produce different colors of light. Different colors of laser are absorbed by different colors of skin, dye particles are decomposed and vaporized by laser energy, and then absorbed and excreted by the body, and the pigment disappears. Laser Dot mole absorbs specific wavelengths through different pigments, and normal skin tissues will not be damaged, so no scars will be left. Experts say that dark black scabs can be formed 12 days after laser Dot mole treatment, and will fall off automatically around 12 weeks. After the scab falls off, tender skin will grow in a few days, but be careful not to expose to the sun and prevent ultraviolet rays. Sometimes due to too much sunlight, the color will deepen, and it will recover in about 3-6 months. 1. During the recovery period of laser Dot mole, the treatment site should be ventilated. Band-aid can be used to avoid infection within 23 days after the recovery period of laser Dot mole, but it is necessary to change the band-aid frequently and keep ventilation. 2. In the recovery period of laser Dot mole, in order to avoid the sun, you must pay attention to sun protection. 3. The most important thing is to wait for the scab to fall off naturally during laser Dot mole recovery. If you remove all the buttons, you will definitely leave a scar. 4. The wound will scab after keeping the treatment surface clean during the recovery period of laser Dot mole. At this time, we should pay attention to avoid local infection. The wound should be waterproof within 2 days after mole removal. If it is facial mole removal, try not to wash your face. You can wash your face after 2 days, but dip it in a dry towel immediately after washing, and be careful not to sweat too much.
