What causes clogged pores and closed comedones?

Acne is often described as a "symbol of youth", and teenagers are the most troubled by it. Excessive secretion of sebum can cause pores to become clogged, which in turn becomes the cause of acne. Acne often appears in the "T-zone" such as the hairline and forehead and nose where sebum secretion is high.

1. Internal factors: 1. Excessive secretion of androgen: It is the main reason for the formation of closed comedones. Especially during adolescence, excessive secretion of androgen in males and females is the main cause of acne. Androgens can directly stimulate the increase of sebaceous glands, promote the keratinization of hair follicles, clog the pores and cause inflammation, resulting in the formation of acne and pimples. 2. Related to women’s menstrual cycle: For some women, acne worsens before menstruation. It is mainly related to changes in hormone secretion. 3. Internal diseases or functional disorders of the body: lesions of organs such as the stomach, kidneys, and liver, especially gastrointestinal dysfunction and constipation can induce the formation of closed comedones. 4. Mental stress, excessive fatigue, lack of sleep, etc. 5. Overeating greasy, spicy and sour foods and sweets.
