If the age spots on the face are small and not particularly deep, and there is no obvious breakage, oozing, bleeding, etc., physical treatment means are usually sufficient. Physical treatment means include freezing, laser, microwave, etc., and even excision can also be solved. If it is relatively superficial, it can be treated directly with photorejuvenation laser. If it is slightly thicker, it can be treated with 1064nm laser or CO2 laser. If it is more extensive and more numerous, it may need excisional treatment, and after excision, it can be biopsied to observe whether there is any risk of cancer. If the area is particularly large and the defective surface is more obvious, flap grafting can be used to improve the local facial aesthetics.
