What does the mole on the back represent?
What the mole on the back represents is the most important question for people. With the rapid development of science and technology, it is no longer important. On the contrary, the method of removing moles is the most concerned issue. According to experts, laser nevus removal is the most commonly used method. The effect of laser nevus removal is particularly ideal, but many people are not particularly clear about the principle of laser nevus removal. Let's ask experts to briefly introduce the principle of laser nevus removal. The principle of laser nevus removal is the photothermal reaction after the tissue absorbs high-energy laser, which makes the local temperature suddenly rise to more than several hundred degrees in a few seconds, and the tissue solidifies and dies, even carbonizes or vaporizes. At the same time, due to sudden fever, the water in the tissue suddenly loses strongly. After focusing, it can be used to cut or cauterize diseased tissue to remove moles. The commonly used lasers for laser nevus removal include carbon dioxide laser, ruby laser and dye laser. The advantages of laser nevus removal are obvious: simple operation, long time consumption, and hemostasis while removing nevus. For some large areas of spots and moles, surgical resection is not needed, and autologous skin grafting can preserve the capacity and function. But laser nevus removal, like other nevus removal methods, will also have some side effects. When the diseased tissue is eradicated, it will also cause different degrees of damage to normal tissue. The most common are superficial scars, hypopigmentation or deposition spots left after laser nevus removal. Attention should be paid to the following matters in laser nevus removal: 1. After laser removal of facial pigmented nevus, it is not necessary to apply it locally or bandage it, just apply 2% gentian violet or antibiotic ointment twice a day. 2. After laser mole removal, contact with face washing water, rain, sweat, etc. is avoided. , so as not to cause the wound moist, infection and affect the healing. 3. The scabbed skin will naturally fall off after the wound heals, making the wound smooth and flat. If the scab skin doesn't fall off on its own for more than one month after laser mole removal, you should go to the hospital for manual scab removal. 4. In addition, the laser removal of facial pigmented nevus must be carried out by medical professionals in regular hospitals. Don't listen to some exaggerated advertisements, and don't go to unlicensed medical practitioners for treatment, so as not to cause disfigurement. For those who don't know about plastic surgery, after listening to the detailed introduction of the above experts, I believe everyone has a further understanding of this.
