The treatment plan for different parts is different. Freckles, sunburn and senile spots can be removed by photon rejuvenation, liquid nitrogen freezing, or carbon dioxide laser, or short-wave Q-switched laser. Pay attention to sun protection after operation, pay attention to using some moisturizing repair products and try to avoid color deposition.
If it is pigmented nevus, the color is light and shallow, it can be frozen with carbon dioxide laser or liquid nitrogen; If it is large or dark, surgical resection is recommended to avoid excessive stimulation of pigment cells by laser and liquid nitrogen, causing malignant transformation.
