Description: There are liquid medicine "washing moles" and liquid nitrogen "freezing moles". The so-called "Dot mole water" actually corrodes the skin with liquid medicine, so that the skin tissue of the mole is necrotic and then falls off. Liquid nitrogen is also similar to the principle of "combustion". When liquid nitrogen hits the mole, the skin tissue will be necrotic and fall off.
Advantages and disadvantages: These two methods are relatively cheap, but they can't take effect immediately, and the recovery time is long, and the wound needs 1-3 weeks to heal. What is more troublesome is that it is difficult to grasp the depth by the method of "melting". If the mole is shallow, it is not clean and may grow back after a while. If it is deep, it is easy to leave pits and scars, but it will become uglier.
Guidance: Don't try this method of removing moles yourself, especially for people with scar constitution. If you really want to do it, you can choose to consult the plastic surgery department of a regular hospital. Under the operation of qualified doctors, the risk will be reduced.

Laser gasification method
Description: Using high-intensity laser energy, the melanocytes of nevus are disintegrated and gasified, crushed into pieces to form powder, and then gently wiped with a cotton swab to fall off.
Advantages and disadvantages: simple and quick. When the laser is used, after the laser vaporizes the nevus tissue, the doctor gently wipes it with a cotton swab, and the tissue is removed, which has strong controllability and can accurately judge the treatment depth and observe whether there is any nevus tissue residue. Generally speaking, most moles can be removed without leaving traces after laser treatment. Only a few large and deep moles may have a small pit. For deep pigment cells, laser nevus removal may still have residues, because the naked eye can't judge clearly 100%, so there is a possibility of recurrence. So individual moles may need to be done several times.
Guidance: Moles that are not in the weight-bearing or rubbing parts (such as soles, toes, palms, nail beds, neck and perineum) can be removed by laser. Especially for those with long hair on moles, there is basically no possibility of malignant transformation, and it is safe to be a laser.
Surgical excision
Description: Take the nevus as the center to do spindle resection, and then suture.
Advantages and disadvantages: to say what method can uproot the mole, moving the knife is the most secure. But when it comes to moving the knife, many people are psychologically afraid that the wound will be bigger and there is a risk of infection. And for people with scar constitution, there is a risk of scar hyperplasia. Generally, there are many moles, which are small in size and large in number. If you have surgery, some will go to war, and the surgery will always leave a small scar. However, for special parts, that is, weight-bearing or rubbing parts (such as soles of feet, toes, palms, nail beds, neck, etc. ), because most of the moles in these parts are borderline moles, which have potential opportunities for malignant transformation. It is best to completely remove them through surgery, and pathological examination can be done to determine their nature. If there are malignant lesions, they can be found and treated as soon as possible.
Guidance: moles in the palm, sole, nail bed, neck and back near the collar, perineum and other load-bearing or friction parts are at risk of malignant transformation. Laser may stimulate malignant transformation, and it is best to do surgical resection. In addition, moles with a diameter greater than 1 cm are also suitable for surgical resection, otherwise the wound will heal slowly after laser, which may easily leave scars.
