Sebaceous cysts can not be cured by applying ichthyol ointment. Sebaceous cysts are benign skin tumors whose cause is not completely clear, but are caused by blockage of the sebaceous gland ducts, which prevents the sebum from being excreted from the body. Sebaceous cysts have no effect on the body and usually do not need to be treated, but when they grow on the exposed parts of the face, they may affect the aesthetics. Sebaceous cysts are often ineffective when treated with medication. Treatment is usually based on surgery, in which the skin is cut open and the entire cyst is removed. Sebaceous cysts are usually treated with surgery, which involves incising the skin and removing the entire cyst. Ointment with ichthyol is a topical herbal medicine that is often used for boils and other suppurative skin disorders, and can be used to promote the drainage of pus and the resolution of infections in sebaceous cysts that have been infected by bacteria. If you have sebaceous cysts, it is recommended that you go to the hospital, complete the relevant examinations, make a clear diagnosis, and treat the symptoms. The medication should be used according to the doctor’s prescription.
