When you ask for removal of colored moles on the body surface, please know about colored moles. 1.Indications: It is superstition to say that moles are related to facial features or fate or fortune or with family members, please don’t believe it. If it is due to aesthetic problem or prevention or suspicion of mole cancer, please actively come to our department for consultation. Our department has the most advanced high-energy pulsed CO2 laser, which has the advantages of thorough mole removal under visualization, accurate direction, precise treatment and minimal damage to normal tissues, which lays the foundation for achieving minimal scarring and the best cosmetic effect after mole removal. That’s why many beauty lovers choose to have their moles removed in our department. Every year, our department removes tens of thousands of moles and has accumulated rich experience in treatment. If a mole is suspected to be malignant, it cannot be lasered. 2.Knowledge about colored moles: There are congenital colored moles and acquired colored moles. Congenital nevus is divided into congenital small nevus (less than 10cm in diameter), congenital medium nevus (10-20cm) and congenital giant nevus (more than 20cm). They are often hyperplastic, hypertrophic and hairy, with clear boundaries. Congenital giant nevi are often located on one or most anatomical areas, such as the scalp, back, chest or limbs, and are surrounded by satellite lesions, and have a higher chance of malignancy. Small congenital nevi have a low chance of malignant transformation and mostly occur after the age of 12. Acquired pigmented nevi occur after birth and are mostly lentil-sized, and are found on exposed areas such as the face. The peak of mole growth is around 20 years old, which is the time when people love beauty the most. Therefore, most of the mole removal patients in our department are young students. 3.How to judge the malignant change of moles: Malignant change of moles is often manifested, such as rapid growth of moles in a short period of time, asymmetric growth of moles, such as sprouting, accompanied by painful or itchy symptoms, easy to break down, easy to bleed, surrounded by a red halo, some accompanied by color changes, or deepening, or decreasing color, and some surrounded by a black halo spreading outward. If you have one of these conditions, you should be cautious and go to the hospital promptly for surgical removal plus pathological examination and follow up on time. It should not be ignored and picked by hand, or treated at a beauty salon, nor is it suitable for laser treatment. The philosophy at this point should be life first, beauty second. First confirm the diagnosis, then deal with it. 4, about the principle of high-energy pulse CO2 mole removal beauty: The reason why high-energy pulse CO2 laser mole removal has a cosmetic effect is that the application of high technology makes the laser energy very high, and at the same time makes the continuous emission of laser into a pulse mode, and the pulse width is very narrow, only about 1ms, so that the lesion tissue is instantly vaporized into ash under the action of laser and is absorbed and removed, and at the same time there is no heat conduction to the surrounding tissues. At the same time, there is no time for heat transfer to the surrounding tissues, so that the thermal damage to the tissues around the lesion is minimized, which facilitates the healing of the wound. 5.On the treatment of congenital moles: Most congenital moles on the face are about 2-3cm in diameter, and if they are distributed in important parts, such as the orbit, the mouth, the nose, or near the middle of the face, it is more difficult to remove them surgically, and the incision scar is not easily concealed, and it is easy to destroy the normal shape of the facial organs and affect the beauty. Laser mole removal is also more obvious due to the larger area of the mole and the scar. However, when the location of mole tissue in the skin does not exceed the middle and lower dermis, photon therapy can be used with good effect, overcoming the shortcomings of surgery and laser. However, if it is still not removed after several treatments, surgical excision or laser is recommended until it is removed without recurrence. The occurrence of malignant change for moles is unknown. If a mole recurs, it should be reviewed in time to prevent malignant change. 6. Post-laser care of moles: After laser removal of moles, there will be depressed trauma, and a few of them are deep to the subcutaneous fat layer. It takes about 2 weeks for the trauma to heal, and about 3 months or even 6 months for the trauma to return to its basic level. During the healing period, the wound cannot be exposed to water and does not need to be disinfected. Oral antibiotics are required to prevent infection and topical antibacterial creams or dressings are carefully specified. The wound does not need to be dried and crusted; a hard crust will prevent the wound from growing flat. After healing, continuously adhere to the topical application of creams or materials that promote scar repair. If there is a mole recurrence or doubt, follow up in time. If it is normal or satisfactory, usually follow up once in 3 months or half a year. 7.Expected cosmetic effect after mole removal: Generally speaking, if the occupancy of the mole on the skin is not very deep, about 2mm in diameter, and there is no infection after surgery, most of the cosmetic effect after mole removal is very satisfactory and there is no obvious scar. The degree of trauma healing scar is greatly related to the patient’s physical condition, the depth of the trauma, whether the postoperative infection is present, and the nutrition and environment of the growth of the trauma.
