Causes of Recurrent Acne Around the Mouth in Women
Acne is a chronic inflammatory skin disorder affecting the pilosebaceous unit. Many women frequently experience acne around the mouth—what causes this? Specific reasons include:

① Hormonal Imbalance
When hormonal balance in women is disrupted—leading to elevated hormone levels—sebum production increases, predisposing individuals to acne. Hormonal imbalances may arise from various factors, including puberty, menstruation, or environmental changes.
② Poor Dietary Habits
Many women prefer spicy and greasy foods and often suffer from chronic constipation and intestinal heat, which can promote acne development around the mouth. It is recommended to adopt healthy dietary habits—consuming more vegetables and fruits—and maintain regular bowel movements.
③ Excessive Sebum Production
Overactive sebaceous glands can also cause acne beneath the lips. Excess sebum readily traps dirt and dust, leading to follicular obstruction; over time, this results in acne formation. This scenario commonly occurs in individuals with oily skin. Daily proper cleansing is advised to prevent pore blockage by excess oil.
④ Other Contributing Factors
Additional factors—including occupational fatigue, high psychological stress, inappropriate skincare practices, long-term oral contraceptive use, drug-induced androgen exposure, and prolonged misuse of cosmetics—can all stimulate excessive sebaceous gland activity and trigger perioral acne.
