The effect of laser to remove age spots is better, it is the commonly used method at present, mainly utilizing the characteristic of laser with penetrating power, it can effectively penetrate the surface layer of the skin, produce local high heat to break down the abnormal pigment of the skin, and finally be cleared by phagocytes in the body, so as to achieve the effect of lightening the spots, moreover the laser has the precision, it can accurately remove the age spots, and there is no damage to the surrounding skin in general, so that it is safe and does not leave scars. There are many kinds of lasers, including CO2 laser and Q-tuned laser, which can remove age spots better. In addition, there is a kind of intense pulsed light with broader photon spectrum similar to the laser principle, i.e. photorejuvenation, which is also more effective in treating age spots. For wart-like age spots that protrude from the skin, CO2 laser is mainly used to carbonize the lesions and thus get rid of the age spots. Age spots that are flush with the skin surface are mainly treated with tuned Q laser, which does not break the skin and leave no scar, and usually 2-3 times of treatment can have obvious effect. After the laser is finished, the area receiving laser treatment should not be allowed to come into contact with hot water usually for 1 week. During the nursing period, hot compresses, sun exposure and other outdoor activities are prohibited, good sun care, and eat less stimulating food, avoid eating photosensitive food, so as to avoid pigment re-deposition.
