What causes pimples at the corners of the mouth?

Generally, "dou" refers to acne. Acne around the mouth may be caused by factors such as dehydration, poor mental health, inadequate oral hygiene, perioral dermatitis, or folliculitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Dehydration

Insufficient hydration in the body or skin can disrupt the skin's oil-water balance, making the skin more prone to oiliness and increasing the risk of acne development around the mouth. Maintaining adequate fluid intake helps preserve the skin’s oil-water balance and reduces sebum production.

2. Poor Mental Health

Long-term stress may disrupt the body's endocrine balance, stimulating sebaceous gland activity and leading to acne around the mouth. Stress can be reduced through physical exercise, listening to music, jogging, or other relaxation methods.

3. Poor Oral Hygiene

Inadequate oral hygiene allows bacteria to enter the skin through the corners of the mouth, potentially causing inflammation and acne. Regular tooth brushing and mouth rinsing help maintain oral cleanliness and prevent bacterial growth that could negatively affect skin health.

4. Perioral Dermatitis

Perioral dermatitis may result from bacterial or fungal infections, causing inflammation of the skin around the mouth and the formation of acne-like lesions, often accompanied by itching, pain, or other discomforts. Treatment may include medications such as erythromycin ointment, ketoconazole cream, or adapalene gel, used according to medical advice.

5. Folliculitis

Folliculitis may be triggered by factors such as sleep deprivation, vitamin deficiency, or skin injury. Inflammation affecting the area around the mouth can lead to acne development, often accompanied by symptoms like itching or pus formation. Treatments may include mupirocin ointment, fusidic acid cream, or isotretinoin gel, applied under a doctor's supervision.

Maintain good skin hygiene and avoid using highly alkaline soaps or skincare products with strong irritants. Keeping a positive mood, maintaining regular sleep patterns, and avoiding late nights are beneficial for overall skin health.
