The chemical burn of 1 mainly depends on the corrosiveness of the liquid medicine to the skin, so that the skin with moles slowly dies and then falls off on its own. The principle of liquid nitrogen is the same. Nitrogen acts on the nevus, which makes the diseased skin necrotic. Compared with others, the treatment price is very cheap, but it can't show the effect immediately, and the recovery time is very long, and the wound healing takes a long time. This method is difficult to grasp the depth of mole removal, which will lead to unreasonable mole removal and will rebound after a period of time. It is suggested that patients should never use this method to remove moles, especially those with scars. It is recommended to go to a professional plastic surgery hospital for in-depth communication.
2 Laser gasification, mainly because the laser can generate huge energy, vaporize and dissolve the pigment in the mole, pulverize it into powder, and then gently wipe it with a cotton swab, and the mole will fall off. It's easy to get rid of moles in this way, and it works quickly. After gasification, the mole will be wiped off with a special cotton swab, and the manual control is particularly strong. You need to know the depth of mole removal very accurately, and then see if there are any moles left. Usually, many moles will not leave any traces after laser removal, unless the moles are particularly large, which will leave a small pit, but it is almost invisible to the naked eye. However, there may be a rebound, so laser mole removal should be done several times.
