Acne is associated with vigorous sebaceous gland secretion, consuming spicy, stimulating foods, or frequently staying up late. In daily life, eating spicy, overly greasy, overly sweet, or strongly flavored foods can stimulate excessive secretion of the sebaceous glands. During the secretion process, when mixed with bacteria on the skin surface, acne infection forms. Therefore, it is essential to maintain a light diet, consume more vegetables, fruits, eggs, milk, and lean meat, and avoid overly greasy fried foods, sweets, or overly spicy foods. It's also important to avoid staying up late, feeling anxious or stressed, and to engage in regular exercise, sweat more, and take more showers, as these can all help with the condition.

How to remove acne marks?

Most acne patients, after undergoing standard treatment, tend to retain some acne marks on their faces. These marks generally do not require special treatment and will gradually fade or disappear over time. Alternatively, patients can opt for red and blue light therapy at hospitals, which can accelerate the fading of pigmentation. They can also visit a standard hospital to have cosmetic laser treatments to remove the marks, but these effects are not particularly fast and require long-term persistence. During the treatment period, it is essential to follow a standard diet and lifestyle practices. It is advisable to avoid spicy and irritating foods, and to prevent staying up late, feeling anxious or tense, or excessive sun exposure, as these factors may worsen the acne marks and increase the difficulty of treatment.

Does acne infect people?

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.

How to treat acne?

Acne is related to several factors including excessive secretion of sebum, consumption of spicy and stimulating foods, frequent staying up late, familial inheritance, and internal hormone levels. There are various treatment methods for this condition, which primarily depend on the individual's age. Treatment can be challenging during adolescence. If it is post-adolescence, treatment tends to be relatively easier. The most common treatment approach involves oral and topical anti-inflammatory medications, and it's effective to combine these with red and blue light therapy at a formal hospital for faster results. Traditional Chinese medicine facial masks can also be used to reduce local inflammation and decrease sebum secretion. However, acne tends to recur, particularly in adolescents. It is crucial for patients to avoid spicy and stimulating foods, not stay up late, and regularly exercise to reduce adverse hormone levels in the body. (Medications should be used under the guidance of a doctor based on specific circumstances.)
