Laser is a commonly used method to remove age spots. It mainly utilizes the penetrating power of laser, which can effectively penetrate the surface layer of the skin and produce local high heat to break up the abnormal pigment of the skin, which is finally cleared out of the body by the phagocytes in the human body, thus achieving the effect of light spot, and the laser has precision, which can accurately remove age spots, and generally there is no damage to the surrounding skin, and it is safe without leaving scar. There are many types of lasers, including CO2 laser and Q-modulated laser, all of which can remove age spots better. In addition, there is another kind of intense pulsed light similar to laser principle with wider photon spectrum, namely photorejuvenation, which is also more effective in treating age spots. For wart-shaped age spots that protrude from the skin, CO2 laser is mainly used to carbonize the skin lesions and thus achieve the purpose of removing age spots. For age spots that are flush with the skin surface, Q laser is mainly used to treat them without breaking the skin and leaving scar, and usually 2-3 times of treatment can have obvious effect. After the laser is finished, the area treated by laser should not be exposed to hot water usually for 1 week. During the treatment period, outdoor activities such as hot compresses and sun exposure are prohibited, and sun care should be done, and stimulating foods should be avoided to avoid re-deposition of pigment.
