Sebaceous nevus healing time varies from patient to patient. It usually needs to be treated before puberty and can usually be cured in 1~2 weeks after successful surgery. Sebaceous nevus is also known as congenital sebaceous gland hyperplasia, often appearing at birth or shortly after birth, mostly occurring on the head and face, and needing to be treated by laser, electrocautery or surgical excision, generally needing to be treated before puberty and needing to be treated thoroughly to avoid recurrence, and can be cured when the wound heals if the surgery is successful, which may be 1~2 weeks. A small number of patients with nevus sebaceous gland may also have symptoms of “neurocutaneous syndrome” such as mental retardation, convulsions, and abnormal eye development. If you have a nevus of sebaceous gland, you should take active treatment under the guidance of your doctor to avoid delaying your condition.
