Acne is a condition caused by excessive secretion of one's own sebaceous glands, consuming spicy and stimulating food, or due to frequent staying up late and family heredity. Eating sweets for a long period of time can easily exacerbate this condition because it tends to increase internal damp-heat and can also stimulate the overproduction of androgens, leading to the worsening of the disease. Therefore, after the appearance of acne, it is essential to regulate one's diet and lifestyle habits. Sweet foods, spicy and stimulating foods, and foods with overly strong flavors should be avoided as much as possible. If the symptoms are severe, it is advised to seek formal treatment at a dermatology department in a regular hospital, avoid picking or squeezing the acne to prevent the later formation of pits or scars, follow proper medication protocols, and complement treatment with red and blue light therapy for potentially better results.
