Hard nodules on the face, but not itchy, common sebaceous cysts and lipomas, after a clear diagnosis of the doctor can choose conservative treatment and surgical resection. 1. Sebaceous cysts: commonly known as “chalk tumors”, are formed when sebaceous glands are blocked in excretion. For cysts that are not infected or ruptured, antibiotics can be used externally to prevent infection, and the cysts will subside in about 1 to 2 weeks. If the cyst recurs frequently or is large in size, it should be surgically removed. 2. Lipoma: Lipoma is a benign swelling, which grows slowly and will stop growing after a certain size, but will not disappear by itself. If there is pain, limitation of movement or rapid expansion, surgical excision and pathological biopsy are recommended. It is advisable to consult a surgeon or dermatologist to determine the cause of the tumor and to follow the doctor’s instructions.
