From the former commonly used potion “mole washing” to the current mainstream laser mole removal, there are more and more means, but also more people can’t decide. In fact, different moles are suitable for different methods to get rid of, what are the advantages and disadvantages of each of the three common mole removal methods? 1, chemical cauterization method Explanation: There are potion “mole washing” and liquid nitrogen “mole freezing”. The so-called “mole water” is actually used to corrode the skin with medicinal water to make the skin tissue of the mole necrotic and then fall off. Liquid nitrogen mole removal is also similar to the principle of “cauterization”, in which liquid nitrogen is hit on the mole and the skin tissue then necroses and falls off. Advantages and disadvantages: These two methods are relatively inexpensive, but they do not work immediately and the recovery time is long, with the wound taking 1-3 weeks to heal after crusting. What’s more, it is difficult to grasp the depth of the “chemical burning” method, if the mole is shallow, it will not be clean and may grow back after a while, if it is deep, it will easily leave a pit and a scar, which will become more ugly. 2.Laser vaporization method Explanation: Using high laser energy, the melanocytes of moles will be disintegrated and vaporized, and will be broken into pieces to form powder, thus achieving the effect of mole removal. Advantages and disadvantages: simple, quick effect, when doing laser, after the laser vaporizes the mole tissue, the tissue is taken off, its controllability is strong and it can accurately judge the treatment depth and observe whether there is any mole tissue left, the disadvantage is that there are pits after treatment. And for moles with very deep pigment cells, laser mole removal may still have residue, and since it is impossible to judge clearly with the naked eye 100%, there is a possibility of recurrence. Guidance: Moles that are not weight-bearing or friction areas (such as soles, toes, palms, nail beds, neck and neckline, perineum) can generally be removed by laser. 3.Surgical excision method Explanation: Make a shuttle-shaped excision with the center of the mole and then sew it up. Advantages and disadvantages: To say what method can uproot a mole, surgery is the most guaranteed. However, when it comes to surgery, many people are psychologically afraid, worrying that the traumatic surface will be bigger and there is a risk of infection. For people with scars, there is also the risk of scar growth. Generally, moles are multiple, small in size and large in number, so surgery is a big deal and always leaves a small scar. However, for moles in special areas, i.e. weight-bearing or friction areas (such as soles, toes, palms, nail beds, neck, etc.), because most of the moles in these areas are junctional moles with potential malignancy, it is better to remove them completely through surgery, and pathological tissue examination can be done to determine the nature. If there is malignant lesion, it can be detected early and get treatment early. Guidance: Moles in weight-bearing or friction areas such as the palms of hands, feet, nail beds, and the back of the neck near the collar have the risk of malignant transformation, and using laser may stimulate malignant transformation, so surgery is best to get rid of them. In addition, moles larger than 1 cm in diameter are also suitable for surgical excision, otherwise the wound heals slowly after laser and may easily leave scars.
