The way to remove moles usually depends on the type, size and location of moles.

1). As long as it is suspected to be malignant, it should be removed and biopsied. I'm afraid the laser will be dirty. Compound nevus and dermal nevus are too deep and protruding. If they want to be cleared, they should be cleared. Larger nevus should be sutured after excision, and even skin grafting (transferring a piece of skin from other places) and skin flap transfer (taking the meat next to it) are needed.

2). Laser laser is a therapeutic method to convert electric energy into light, which is suitable for small and shallow nevus, such as flat commissure nevus.

3) High-frequency electrocautery destroys cells with heat energy.

4). Liquid nitrogen is frozen at a low temperature of-196 degrees Celsius, but it is rarely used.

Guiding opinions:

5). There are two kinds of medicines to remove moles. One is to use traditional Chinese medicine to remove moles, such as Tian Jian nevus Meijing. Using biotechnology, the effect is good, the speed is fast, and it is not easy to leave scars. One is chemical etching to remove moles. The disadvantage is that it is difficult to control the depth and range of cauterization. If it is broken, there will be concave holes, some of which are deep. Therefore, we should carefully identify when choosing drugs. Laser Dot mole is a very mature method to remove moles at present. It doesn't usually leave scars. You need not worry too much. Whether Dot mole will leave a scar depends on the depth of the mole, Dot mole's methods and instruments, and the doctor's skills.
