Sebaceous cysts are caused by sebum secreted by the sebaceous glands that is not properly discharged from the hair follicle opening and accumulates in the glands, forming cysts. Sebaceous cysts on the face can cause infection of the surrounding tissues, skin breakdown and even scarring. Surgery is usually recommended for removal, which requires complete excision of the lesion and cleaning of the local tissue. Depending on whether the sebaceous cyst has become infected or not, there are differences in the treatment: 1. no infection: the surgery requires the entire internal wall of the cyst to be stripped clean, and if it is not stripped clean, it may lead to the recurrence of the cyst; 2. infected: if the cyst is infected and is accompanied by redness, swelling and heat, it is not suitable for surgery. Because the recovery is slow and the surgery is accompanied by the risk of re-infection. It is recommended to take oral anti-inflammatory drugs to control the inflammation first, and then proceed to surgery afterwards. If the sebaceous cyst is large and affects normal life, after surgical removal, the patient can slow down the scar formation by applying appropriate topical medication or using physical therapy while waiting for the stitches to be removed. If scars have already formed, laser treatment can be performed to soften the scars, etc. In daily life, it is necessary to pay attention to personal hygiene, eat a light diet, avoid smoking and alcohol, and eat less spicy and greasy food and food with high sugar content. If the cyst symptoms continue to worsen, you need to go to the hospital for medication and surgery.
