Both pimples and acne belong to acne, which is a skin disease caused by many factors. Constant acne on the face may be related to androgen levels, abnormal keratinization of peripheral cells, inflammatory reactions, genetic factors, emotional factors, dietary factors and so on. 1. Androgen Levels: Increased levels of androgens in the body after puberty can cause sebaceous glands to enlarge and secrete large amounts of sebum, which clogs pores and forms acne. Acne is commonly found on the face and manifests as pimples, papules and pustules. 2. Abnormal keratinization of peripheral cells: This will lead to the follicle opening becoming smaller and blocked, and the sebum discharge will be obstructed, resulting in the accumulation of sebum and the formation of acne. 3. Inflammatory reaction: Enhanced secretion of sebaceous glands helps the growth and reproduction of Propionibacterium acnes, which can damage the tissues around the hair follicles, leading to inflammatory reaction of the skin, thus aggravating acne. 4. Genetic factors: Acne runs in families, and when parents suffer from acne, their children are more likely to develop acne. 5. Emotional factors: Acne can be aggravated by stress, psychological pressure and overwork. 6. Dietary factors: Acne may be aggravated by spicy, stimulating and high-sugar diets, such as chili peppers and strong alcohol. 7. Menstrual cycle: Some women experience or aggravate acne before menstruation and during pregnancy due to changes in hormone levels in the body. Acne is caused by a number of factors and is often the result of a combination of factors. It is recommended that people with acne on their face should seek medical attention in a timely manner and under the guidance of a doctor to carry out targeted treatment.
