Hairy nevus on the face belongs to a kind of benign tumor, which is related to the increase of melanin cells in the organism, and the method of removing it is mainly through laser treatment, liquid nitrogen freezing treatment and surgery according to the size of the hairy nevus.
1. Laser treatment: If the nevus is relatively small, it can be treated by laser, which utilizes the selective light source of the laser to act on the pigmented area, and will decompose the pigment into tiny particles, which will be absorbed by the human body, and the pigment will gradually fade away.
2. Liquid nitrogen freezing treatment: Liquid nitrogen freezing can be used to destroy the hair follicles and pigment particles in the area of nevus, which is usually applicable to small area of nevus.
3. Surgery: If the size of the nevus is large and may invade the dermis, surgery can be considered to remove the nevus completely. If there is ulceration on the nevus, it should be alerted to the possibility of deterioration and histopathological examination should be taken.
Patients with hairy nevus should go to the dermatology department in time, strictly follow the doctor’s instructions, and take the appropriate method of treatment.
