Can moles leave scars?
At present, there are many plastic surgery methods, and each method has its own advantages and disadvantages. First of all, the doctor should check the state of the mole and make suggestions before making a decision.

Electric combustion method

Methods: The principle of electric heating and high temperature burning was used to remove the nevus caused by burning and carbonization.

Advantages: simple operation, which can be operated by some beauty salons.

Disadvantages: it is difficult to control the degree of burning, and it is easy to leave scars. Indications: nevus with a diameter of 0.3-0.5 cm.

Laser Dot mole method

Methods: At present, laser can be used to remove superficial nevus, such as ruby laser, chromium laser or dye laser. If it is a large and deep mole, it should be removed by carbon dioxide ultra-pulse laser.

Advantages: Laser nevus removal can control the best spot size and depth, and it is not easy to leave scars and infections.

Disadvantages: if the mole is too deep, you may still have to play several times. Indications: Most of them can be used, including deep and shallow nevus.

Surgical excision

Methods: The pathological tissues around the nevus were surgically removed.

Advantages: this method can choose to partially or completely remove the diseased tissue, and different treatment methods can be carried out according to the nature of hydatidiform mole.

Disadvantages: it is difficult and takes a lot of time. This method is rarely used in general moles.

Indications: large and prominent nevus with a diameter greater than 0.6 cm.

Chemical etching method

Methods: Generally speaking, 50% triazole carbonic acid solution or alkaline reagent, such as sodium hydroxide, is suitable for nevus.

Advantages: Triazole carbonic acid solution is not easy to burn the skin and cause scars; Alkaline solution is corrosive and may take effect soon.

Disadvantages: triazole carbonic acid solution acts slowly, and the deeper mole may be 10 times; Sodium hydroxide is not easy to control the corrosion depth, and it is easy to cause deep scars.

Indications: Nevus with light color and light position.

freezing method

Methods: Cryopreservation with liquid nitrogen, high-speed freezing of pigmented nevus tissue, formation of water sores around pigmented nevus cells, and then spontaneous shedding.

Advantages: The depth of the injury is relatively easy to master, usually once, and it is not easy to cause obvious scars.

Disadvantages: large and thick moles can only be taken out after repeated freezing, and special instruments must be equipped, and the doctor's skills are also very important.

Indications: Flat nevus with a diameter of 0.3-0.5 cm, including freckles.
