If the mole in the eyebrow grows back after being picked off, it means that there is residual tissue, and the patient only picks off the skin tissue on the surface of the mole, and the residual tissue grows back after normal metabolism. Patients can remove moles through surgical excision, physical therapy, etc. It is not recommended to pick it off by oneself. Usually, most pigmented nevi do not need treatment, but if they affect the patient’s appearance or mental health, treatment can be chosen. Surgery can be given to those who are requested by the patient, have severe symptoms or have a tendency to become malignant (such as sebaceous nevus). In addition, physical treatments such as laser can be used as a last resort for pinpoint-sized pigmented nevus. 1. Surgical treatment: This type of treatment is mainly for pigmented nevus, sebaceous gland nevus, epidermal nevus and so on. The disadvantage is that this method may leave a certain degree of scarring; if the scope of the lesion is too large, it may need to be removed in stages. 2. Physical therapy: physical therapy (such as YAG laser, CO2 laser, etc.) can be considered for nevus of ota and smaller pigmented nevi. However, this kind of treatment is forbidden for people with scarred physique; the nevus cells suspected to have malignant tendency should not be treated with laser; the effect of laser treatment for nevus of larger size may not be ideal. It is recommended that patients go to regular hospitals and choose appropriate treatment plans with the help of professional doctors. Do not pick and scratch and stimulate the nevus on your own, as there is a risk of provoking the nevus to lead to cancerous changes.
