Acne belongs to a disease caused by the excessive secretion of one's own sebaceous glands and an infection of the skin surface by acne propionic acid bacillus. This disease is not contagious, and it cannot be transmitted to others by touching each other or sharing towels. However, the disease has a strong recurrence, especially in patients who are in puberty. If their diet and lifestyle are not monitored in the short term, they will relapse quickly. It is recommended to receive formal treatment at a dermatology department of a regular hospital, with oral medication and topical medication. The combination of red and blue light effects can speed up the recovery. After recovery, it is crucial to maintain a standard diet and lifestyle, avoid spicy and irritating food, and try not to stay up late, feel anxious, or tense. Avoid misusing cosmetics to prevent clogging pores, which could worsen the condition. Regularly strengthen exercise, sweat more, and bathe more often.
