Sebaceous cysts are a type of benign proliferation related to vigorous sebaceous gland secretion and bacterial infection on the skin surface. These cysts feel relatively soft. The most common treatment is a minor surgery at a dermatology department of a reputable hospital to completely remove the cyst. Generally, oral and topical medications are ineffective against sebaceous cysts. If left untreated, the cyst may continue to grow, causing pain and even rupture. Therefore, once detected, it is crucial to seek timely treatment. After treatment, it is important to adopt healthy dietary and lifestyle habits, avoid spicy and irritating foods, refrain from staying up late, and avoid soaking in public baths or swimming, and try not to keep pets at home.
