Mole spotting is a common term for the non-surgical removal of relatively small moles by a variety of physical and chemical means. Depending on the method, it can be broadly categorized into freezing, chemical cauterization, electrocautery, and laser vaporization. Each method may have its own advantages and disadvantages, but I believe that laser vaporization is a relatively advanced technology, which has the advantages that other treatment methods do not have, that is, fine and controllable. Freezing is mostly done with liquid nitrogen in a white mist. The low temperature freezes the skin on contact and produces blisters. Chemical potion or powder has not been specifically studied, mostly village roadside home ancestral technology, red and green medicine a coating of smoke on the good, it is estimated that similar to the sulfuric acid cauterization process. Ionizer is before the hospital plastic surgery or dermatology application of the machine, compared with the first two has improved, but similar to the electrostatic discharge type of current heat carbonization of the tissue, the control is still slightly lacking, basically in the three hospitals have not been used, but in some of the small beauty parlors used to pretend to be a laser treatment to cheat people, charging a lower fee. Gasification laser, now mainly refers to super pulsed CO2 laser, can be imagined as a tiny column of light, the water molecules within the column of heat into gas, so that the skin level lesions can be treated precisely. Let’s say that the skin is a white sandy beach and the lesions are the black sand on the white beach. Freezing and chemical cauterization is like pouring toxic liquid on it, the sand who suffered who died or the kind of bubbling —- imagine the ancient costume drama found in the wine toxic to the ground when a splash of the picture, you can only roughly control the amount of liquid, but you can not control the liquid seeped down how deep, but also can not control the toxicity of the intensity of the damage, that is to say, the depth of the damage is determined by the interaction between the liquid itself and the sand, you can only roughly draw a circle. Poor control, or the deeper black sand is not destroyed, or the black sand is gone and the fluid continues to go deeper destroying the white sand (normal skin), and the destruction of normal skin means an increased risk of scarring. Ionization seems like a pen that emits electrical sparks with a metal pin on the head, and somehow the tip of the metal pin is made to discharge heat into the skin, as in the beach example, where there is a man-made ball of static electricity that discharges electricity into the black sand – lightning, ah, carbonizing the black sand. But since it’s electricity generating heat, there may still be a certain area of radiation that creates a hemispherical damage centered on the point of contact–imagine a crater, still lacking in finesse. And now the ultra-pulse CO2 laser can be compared to a vacuum cleaner canister, can be a certain area of black sand gasification suction, of course, if the operation is not appropriate may also be sucked away some white sand or leave some black sand, but from the refinement of the laser is undoubtedly now the best choice, with a fine, where to hit where the ability to put in and out of the ability. There are still some students who want to know if a mole can be cured cleanly, without recurrence, without leaving pit-like scarring? Good question, or the beach example. Let’s say the beach is a total of two meters thick, and underneath is the rock (fat layer). Assuming that the sand (skin) has some ability to regenerate, as long as there is still a meter of sand left it can grow back to an untraumatized beach – flat and without pits, isn’t that great news? But who can control exactly what layer the black sand is in, and who says it has to be within a meter of the ground? And because black sand has the ability to regenerate too! As long as there is black sand remaining there is a possibility of recurrence. As long as the black sand exists more than a meter underground you’ll just have to choose between relapse and leaving a pit. Of course, before treatment, the current technology does not have a way to accurately assess the depth of the mole, but in the treatment of a layer by layer of black sand suction away black sand while treating and observing, as long as the bottom is still black, we have to continue to go down the treatment until you can not see the black sand, thus preventing recurrence, until the black lesions visible to the naked eye to completely clear up the end of the ah. Therefore, sometimes it is really not the doctor’s level is low, the machine is not advanced enough, it is really the dilemma of the disease itself. General doctors will try to control the removal of black on the basis of as much as possible not to damage the normal skin, there is no needless sacrifice, and this is the test of the doctor and the machine place. So, can the black mole point, point can recur, point can not leave a pit, you should be able to see some from it.
