Age spots can be removed by liquid nitrogen freezing, laser surgery or scraping. 1. Liquid nitrogen freezing: localized skin lesions are destroyed and removed by liquid nitrogen freezing, which can effectively remove age spots, but it is easy to have residue after treatment. 2. Laser surgery: according to the principle of selective photothermal effect, using a certain specific wavelength of laser to act on the surface of the skin, on the target tissues, such as melanin, which absorbs heat and destroys the pigment and pigment particles, and the pigment particles are broken down by heat bursting, so as to achieve the effect of removing age spots. 3. Surgical treatment: it can be removed by surgery, such as scraping, using spatula to scrape the skin lesion area with force, so as to scrape the skin lesion cleanly and achieve the purpose of removing age spots. When age spots appear on the body, patients should go to the hospital in time and give targeted treatment under the guidance of doctors.
