What causes pustules on the nose?

In general, pustules on the nose may be caused by poor dietary habits, folliculitis, rosacea, nasal vestibulitis, or nasal furuncle. Patients should promptly visit a正规 hospital to identify the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Poor dietary habits: Long-term consumption of high-fat, high-sugar, spicy foods, or excessively hot and irritating foods may increase sebum secretion, promote follicular inflammation, and lead to pustule formation on the nose. It is recommended that patients improve their dietary habits by consuming more light and easily digestible foods such as millet porridge or vegetable porridge. Local warm compresses may also help alleviate symptoms.

2. Folliculitis: Folliculitis refers to infection or inflammation of the skin tissue surrounding hair follicles, resulting in pustules or blisters. Patients may use fusidic acid sodium ointment, mupirocin ointment, or compound polymyxin B ointment as directed by a physician. Additionally, maintaining cleanliness and hygiene of the nasal area and avoiding irritant cosmetics are important.

3. Rosacea: Rosacea is a chronic skin condition that typically affects facial skin but may sometimes involve the skin around the nose. It leads to increased sebum production, causing acne or pustules. Patients may be prescribed erythromycin ointment, benzoyl peroxide gel, or doxycycline hydrochloride tablets under medical supervision.

4. Nasal vestibulitis: This condition involves inflammation of the mucous membrane in the nasal vestibule, often caused by bacterial or viral infections or other irritants. Nasal vestibulitis is commonly associated with follicular inflammation and increased sebaceous gland secretion, leading to pustule formation on the nose. Under medical guidance, patients may apply metronidazole gel, clindamycin ointment, or Bactroban (mupirocin) ointment for improvement.

5. Nasal furuncle: A nasal furuncle is a localized suppurative inflammation caused by infection of hair follicles or sebaceous glands around the nose. It is usually accompanied by pain, redness, swelling, and local warmth, forming a pustule. Patients may take oral antibiotics such as amoxicillin capsules, cefaclor dispersible tablets, or penicillin V potassium tablets as prescribed by a doctor.

For pustules on the nose, it is recommended to maintain facial cleanliness, avoid squeezing the lesions to prevent spreading infection, and seek timely medical evaluation and treatment.
