What is the reason for the long closed acne on both sides of the cheek?

Whitehead acne is whitehead acne. The main reasons for whitehead acne on both sides of the cheeks are as follows: 1. The secretion of sebaceous glands is strong. The secretion function of sebaceous glands directly affects the amount of oil secretion from the skin. When the sebaceous glands are stimulated by various factors, such as androgen levels. Elevated, endocrine disorders, etc., can cause them to secrete too much sebum. Excessive sebum secretion is easy to accumulate in the hair follicle, creating conditions for the formation of whitehead acne. 2. Abnormal hair follicle keratosis Under normal circumstances, the keratinocytes of the hair follicle mouth will fall off regularly to keep the hair follicle unobstructed. However, if the hair follicle keratinization process is abnormal, the keratinocytes cannot fall off normally, which will make the hair follicle mouth smaller and narrower, resulting in sebum and keratin and other substances blocked in the hair follicle, thus forming whitehead acne. 3. Bacteria infected with Propionibacterium acnes and other bacteria in the hair follicle are prone to excessive reproduction in a sebum rich environment. The metabolites of these bacteria can trigger an inflammatory reaction, further exacerbating hair follicle blockage and acne formation. If whitehead acne is severe or persists, you should seek medical attention promptly and seek the help and advice of a professional doctor.
