In daily life, many women who love beauty like to go to beauty salons or streets to get moles, and in dermatological clinics, many patients also ask for moles. So, can "moles" be removed casually? "Nevus" is called nevus cell or melanocyte nevus in medicine, which is a skin manifestation caused by the increase of melanocytes in epidermis and dermis. If it is papule or nipple-like appearance or pedicled skin, it is clinically called intradermal nevus; Slightly higher than the leather surface is mostly mixed mole; Not higher than the skin surface is the borderline nevus. As we all know, "mole" is a benign tumor, which generally does not affect health. For intradermal nevus and mixed mole above the skin surface, laser or cryotherapy can be used for cosmetic treatment, and satisfactory results can be obtained. However, due to individual differences, some patients may leave slight scars after treatment; Even some people with specific constitutions will have keloids and need to be reminded. Sometimes it is not easy to remove the borderline nevus by laser or freezing, and there are cases of recurrence. It should be noted that pigmented nevus growing in the palm, lips and vulva are mostly borderline nevus, which may cause cancer if rubbed and pressed frequently. Therefore, the borderline nevus growing in these parts should be completely removed by surgery to avoid leaving future troubles, while borderline nevus growing in the face or other non-friction parts generally do not need to be harassed by radical methods, such as laser, freezing and drug corrosion. Because repeated and improper stimulation is also necessary. If you want to remove it by laser, I can give you some suggestions: laser application:1; The most common tattoos and eyebrow tattoos: artificial implantation of pigment in the dermis, or accidental injury that causes pencil lead and iron powder to enter the dermis. Generally, only a few laser treatments are needed to solve the problem. 3045 Q-switched dual-wavelength medical laser beauty instrument outputs 1064 nm and 532 nm, and 1064nm Q-switched laser has strong penetration and can reach melanocytes or black-blue dye particles in deep skin. Q-switched laser at 532 nm can be well absorbed by black-red pigment and can effectively remove black-red pigment. So as to completely remove the pigment. 2. The principle of laser therapy is that laser instruments produce high-intensity beams, and different types of lasers can produce different colors of light. The naked eye color of laser is the key to treatment. Different colors of laser are absorbed by different colors of skin, and dye particles are decomposed and vaporized by laser energy, sealing blood vessels, and then the dye particles are absorbed by the body and excreted, and the pigment disappears. Because the laser of a certain wavelength is only absorbed by the pigment of the corresponding color. Only diseased cells can absorb specific laser, while normal skin tissue will not be damaged, so it will not leave scars. Advanced laser technology can also control the depth of laser reaching the skin, and adjustable pulse can minimize skin damage. Generally, the skin can return to normal within 7 days to 10 day, without affecting people's normal life. During the operation, the treatment time is only a few minutes at a time, and at most it is ten minutes. After each treatment, the skin goes through a metabolic process of natural absorption, so the treatment interval is generally 2 ~ 3 months. According to the size, quantity and depth of pigment and vascular diseases, some treatments can achieve the expected effect once or twice, and generally it takes 4 to 6 times to completely solve the problem. 3, the characteristics of laser cosmetic treatment 1) does not damage the skin, hair follicles, does not produce scars, only removes pigments. 2) Pigments that cannot be removed by drugs and other methods can be removed. 3) The pain is small and no anesthesia is needed. 4) Fast recovery and little influence on normal work. 5) cold light sterilization, no cross infection, no special care after operation.
