What causes pimples around the mouth?

In general, acne refers to pimples. The occurrence of acne around the mouth may be caused by improper facial cleansing, poor dietary habits, endocrine disorders, polycystic ovary syndrome (PCOS), or irritable bowel syndrome (IBS). It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Improper Facial Cleansing

Failing to wash the face regularly or inadequately cleansing it may lead to clogged hair follicles around the mouth with oil or dirt, thereby triggering acne. It is important to wash the face morning and night using a gentle facial cleanser to remove excess oil.

2. Poor Dietary Habits

Frequent consumption of spicy, greasy, or other irritating foods may stimulate the skin around the mouth and trigger acne. Increasing water intake appropriately can promote metabolism and toxin elimination in the body, while reducing the intake of irritating foods.

3. Endocrine Disorders

Long-term mental stress or excessive pressure may affect hormone secretion and balance in the body, leading to endocrine disorders. Hormonal imbalances may stimulate sebaceous glands to produce excess oil, resulting in acne around the mouth, often accompanied by symptoms such as decreased libido and menstrual irregularities. Treatment may include medications such as tanshinone capsules, spironolactone tablets, or adapalene gel, used according to a doctor's advice.

4. Polycystic Ovary Syndrome (PCOS)

Long-term exposure to organic pollutants may increase the risk of developing polycystic ovary syndrome. Abnormal androgen levels may lead to abnormal keratinization of hair follicles and impaired sebum excretion, subsequently causing the aforementioned symptoms, typically accompanied by menstrual irregularities and obesity. Medications such as metformin hydrochloride tablets, clomiphene citrate capsules, or dydrogesterone tablets may be used under medical supervision.

5. Irritable Bowel Syndrome (IBS)

Abnormal intestinal motility and visceral hypersensitivity are primary causes of IBS. Harmful substances produced due to gut microbiota imbalance may affect the skin via the bloodstream, triggering or worsening acne around the mouth. This may be accompanied by symptoms such as abdominal pain, diarrhea, or constipation. Treatment may include medications such as lactasin tablets, bifidobacterium triple viable capsules, or pinaverium bromide tablets, used under a doctor’s guidance.

Maintain good facial hygiene by using mild facial cleansers and avoid over-cleansing or excessive friction on the skin.
