Sebaceous cysts are benign hyperplasia formed due to vigorous secretion of one's own sebaceous glands and are somewhat related to inflammatory infections. Oral and topical anti-inflammatory drugs are ineffective for this condition. The most common treatment is a minor surgery to completely remove the cyst sac and tofu-dreg-like substances inside. You can seek formal treatment in the dermatology department of a regular hospital. This surgery is minor and does not require hospitalization; it generally can be cured on the same day. After the surgery, the wound needs about a week to heal. This disease has a certain recurrence rate. After recovery, it is crucial to standardize your diet and lifestyle, avoid spicy and irritating foods, try not to stay up late, regularly exercise, sweat more, and take more showers.
