The darkness around your nose could be caused by a few different skin conditions, including:
- Melasma: This common skin condition causes patches of brown, tan, or blue-gray discoloration on the face. It often affects the cheeks, chin, nose bridge, forehead, and above the upper lip. [1, 2, 4, 5, 6, 7, 8]
- Seborrheic dermatitis: This condition can cause a rash that may look darker or lighter in people with brown skin. It commonly affects the nose, eyebrows, ears, eyelids, chest, armpits, groin area, or under the breasts. [9]
- Rosacea: This condition can cause redness and swelling on the face, often affecting the cheeks, nose, chin, and forehead. It can also cause dark discoloration. [3]
- Vitiligo: This condition causes patches of skin to lose their color. In people with darker skin tones, the contrast between their natural skin color and the lighter area(s) makes vitiligo stand out. [2]
- Blue discoloration: This can be a sign of low oxygen levels in the blood. [5]
It's important to see a dermatologist to get a diagnosis and determine the best treatment for your specific case.
