What Causes Darkening Around the Mouth, Lips, and Chin?

Darkening of the corners of the mouth, lips, and jawline can be confusing and concerning, and this condition can be caused by various factors. Common causes include hyperpigmentation, cheilitis, and melanoma. For accurate diagnosis and effective treatment, it is recommended to seek medical attention promptly for professional examination and assessment.

1. Hyperpigmentation: Frequently consuming foods containing melanin, such as black sesame paste, may lead to the deposition of pigments on the corners of the mouth, lips, and chin. In such cases, special treatment is usually not required, and adjusting the diet to maintain a lighter intake is sufficient. Hyperpigmentation is generally harmless, but if accompanied by other symptoms, consulting a doctor is still necessary.

2. Cheilitis: Cheilitis can be caused by local irritation, such as prolonged use of fluoride toothpaste or certain cosmetics, or by bacterial infections. Cheilitis causes inflammation of the skin and mucous membranes, manifesting as redness, swelling, peeling, and itchiness. Treatment can involve medications like Triamcinolone Acetonide and Econazole Nitrate Cream or Dexamethasone Acetate Cream, used under a doctor's guidance. Maintaining good oral hygiene and avoiding excessive use of irritating products are also important.

3. Melanoma: This condition is more serious and may be related to genetic factors or excessive sun exposure. Melanoma can cause black patches on the skin, which may be accompanied by pain and ulceration. Treatment usually involves surgical removal of the lesion and may require postoperative radiotherapy or chemotherapy to prevent recurrence. Early detection and treatment are crucial, so if unexplained black patches appear, medical attention should be sought promptly.

Apart from the above causes, other skin conditions such as vitiligo may also cause similar symptoms. In daily life, maintaining local cleanliness and hygiene and avoiding scratching the affected area with hands are good habits for skin health. If darkening of the corners of the mouth, lips, or jawline is observed, seeking medical attention promptly is a wise choice. Through professional diagnosis and appropriate treatment, this condition can be effectively managed and improved. Maintaining a healthy lifestyle and regular health check-ups will help prevent and detect potential health issues early.
