Sebaceous nevus is a kind of misshapen tumor formed by abnormal development of sebaceous glands, which can be removed by laser, and can also be removed by liquid nitrogen freezing and surgery. Sebaceous nevus belongs to a kind of benign misshapen tumor, preferably occurring on the head, face or neck, manifested as local skin elevation, yellow color, mostly has no effect on the health, the only effect on the patient is the change of appearance, which affects the appearance. Patients can be removed by laser treatment, but it is not recommended to treat sebaceous nevus in the scalp area with laser treatment, so as not to damage the pores, resulting in later hair growth obstacles. It should also be noted that laser treatment can only flatten localized lesions, but deeper skin damage cannot be removed and sebaceous nevi can recur. Similarly liquid nitrogen cryotherapy can also recur. Surgical excision is the only way to treat sebaceous nevus completely. Consult your physician for advice.
