Women with acne on their chin generally do not have gynecological issues. Acne on the chin is usually caused by various factors, including excessive oil production, clogged hair follicles, bacterial infection, and hormonal changes. The chin is one of the most common areas where acne occurs. It is necessary to visit the dermatology department of a hospital and cooperate with doctors to take targeted measures for treatment. When women enter their menstrual period, the hormone levels in their bodies change, which may lead to acne on the chin. During pregnancy, hormone levels in the body also change, which may cause acne on the chin to appear or worsen. Polycystic ovary syndrome is a common endocrine disorder that leads to an increase in androgen levels in women. High androgen levels may increase oil production, thereby triggering acne. It is generally not caused by gynecological issues. During the treatment of acne on the chin, it is also important to keep the facial skin clean and avoid consuming overly stimulating foods.
