Acne is a medical term, commonly known as pimples or acne. These two are the same disease, caused by the infection of Propionibacterium acnes, and are related to one's own active sebaceous glands, eating spicy and stimulating food, or frequently staying up late. Once diagnosed with this condition, it is important to receive systematic and formal treatment to prevent recurrence. Treatment can include oral and topical medications from a dermatology department in a formal hospital, and combining this with red and blue light therapy may yield better results. Avoid scratching or popping the acne, as this can lead to scarring or pits. After recovery, it is crucial to maintain a proper diet and lifestyle over the long term, avoiding staying up late and consuming spicy and stimulating foods to prevent the condition from recurring.
