Nevus is medically called nevus cell or melanocytic nevus, which is a skin manifestation caused by an increase in melanocytes in the epidermis and dermis. If it is a rash that is higher than the skin surface, has a dome-like or nipple-like appearance, or is pedunculated, it is clinically called an intradermal nevus; those that are slightly higher than the skin surface are mostly mixed nevus; those that are not higher than the skin surface are junctional nevus .

Introduction to the advantages and disadvantages of mole removal methods

Chemical etching method

Indications: moles with lighter color and lighter location.

Method: Generally, a 50% trizocarbonate solution or an alkaline agent such as sodium hydroxide is applied to the mole.

Advantages: Trizocarbonic acid solution is not easy to burn the skin and cause scars; alkaline solution is highly corrosive and may be effective quickly.

Disadvantages: The effect of trizocarbonate solution is slow, and it may be applied up to 10 times for darker moles; sodium hydroxide is not easy to control the depth of corrosion and may cause deep scars.

Electric cautery method

Indications: Moles with a diameter of 0.3-0.5 cm.

Method: Apply the principle of electric high-temperature burning to remove moles due to burning and carbonization.

Advantages: Easy to operate, some beauty salons may be able to operate it.

Disadvantages: Difficult to control the degree of burning and easy to leave scars.

Freezing method

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

Method: Freeze with liquid nitrogen to freeze the nevus tissue very quickly, causing the cells around the nevus to form water sores and then fall off on their own.

Advantages: The depth of damage is relatively easy to grasp, it can usually be cured in one session, and it is unlikely to cause obvious scars.

Disadvantages: Large and thick moles need to be frozen multiple times to cure, and special equipment is required. The doctor's skills are also very important.

Laser method

Indications: Most can be used, including dark and light moles.

Method: At present, superficial moles can be removed using laser, such as ruby ??laser, chromium laser or dye laser; if it is a larger or deeper mole, carbon dioxide ultra-pulse laser should be used. Remove.

Advantages: Laser mole removal can control the size and depth of the optimal light spot, and is less likely to leave scars and infections.

Disadvantages: For moles that are too deep, you may still need to do the treatment in stages.

Surgical method

Indications: Large and raised moles with a diameter of more than 0.6 cm.

Method: Surgical removal of the diseased tissue around the mole.

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

Disadvantages: It is difficult and takes a lot of time. This method is generally rarely used for ordinary moles.
