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 breakouts around the mouth—what causes this? Specific reasons include the following:
① Hormonal Imbalance
When hormonal balance in women is disrupted, elevated hormone levels can stimulate excessive sebum production, predisposing individuals to acne. Causes of hormonal imbalance are diverse and may include 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 fruits and vegetables—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 pore obstruction and, over time, acne formation. This condition commonly occurs in individuals with oily skin.
④ Other Contributing Factors
Additional factors—including physical fatigue, high psychological stress, inappropriate skincare practices, long-term oral contraceptive use, drug-induced androgen exposure, and prolonged misuse of cosmetics—can all trigger excessive sebaceous gland activity and contribute to perioral acne.
