Mole is a very common thing on human skin, and it is inevitable that everyone will have some moles on his body or face. Because moles can affect appearance and even health, removing moles has become the choice of many beauty lovers. There are many ways to remove moles, and surgical removal is one of them. So which moles need to be removed? Let's have a look. There are many ways to remove moles by medical beauty, but some methods are no longer used because they may leave scars. At present, the commonly used methods to remove moles are laser and surgery. There are differences in surgical indications between the two methods of nevus removal. The principle of laser nevus removal is that the laser instrument produces a high-intensity beam. Different types of lasers in the beam are absorbed by different colors of skin, and dye particles are instantly decomposed and vaporized by laser energy to seal blood vessels. Then the body will absorb the decomposed dye particles and discharge them out of the body, and the pigment will fade. Laser nevus removal is more suitable for smaller nevus, such as the size of a needle tip. But if the mole on the skin is relatively large, like the size of mung beans, then experts advocate surgical removal. For professional doctors, surgical mole removal is as convenient as laser mole removal, and the scope and depth of mole removal can be well controlled, and there is generally no risk of recurrence. Surgical removal of nevus can not only safely and thoroughly remove the diseased tissue at one time, but also effectively avoid recurrence. Moreover, the plastic surgery department is doing minimally invasive surgery, and almost no incision marks can be seen after postoperative recovery. However, attention should be paid when removing moles: people with systemic blood diseases, poor coagulation function, diabetes, hyperthyroidism or scar constitution must be cautious under the guidance of doctors. Experts remind that beauty seekers who have surgery to remove moles must remember to choose a regular hospital.
