What causes peeling skin on both sides of the nose?

Peeling skin on both sides of the nose may be caused by dry environment, excessive cleansing, seborrheic dermatitis, eczema, rosacea, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a healthcare professional. Specific analysis is as follows:

1. Dry environment: Prolonged exposure to air-conditioned rooms or living in regions with dry winter climates can lead to skin moisture loss, causing dryness and peeling on the skin around the sides of the nose. It is recommended to use a humidifier to maintain indoor humidity and apply moisturizing lotion to the skin around the nose.

2. Over-cleansing: Frequent use of facial cleansers, makeup removers, and similar products can easily disrupt the natural oil layer on the skin's surface, leading to moisture loss and resulting in peeling on the sides of the nostrils. It is advised to wash the face with water before bedtime and reduce the frequency of using cleansing products appropriately.

3. Rosacea: This condition may be related to abnormal blood vessel function, genetic factors, and others. Rosacea may cause dysfunction of the nerves regulating blood vessel dilation and constriction, leading to capillary expansion and resulting in the aforementioned symptoms, possibly accompanied by facial redness, stinging, or burning sensations. Patients are advised to follow medical instructions when using medications such as erythromycin ointment, fusidic acid cream, or tretinoin cream.

4. Seborrheic dermatitis: This may be associated with consuming excessively greasy or sweet foods, high levels of mental stress, and other factors. The condition may lead to excessive sebum production, clogging pores, and cause peeling on the sides of the nostrils, possibly accompanied by red patches and mild itching. Patients are advised to follow medical guidance when using medications such as sulfur ointment, compound sulfur cream, or vitamin B6 tablets.

5. Eczema: This may result from immune system abnormalities, food allergies, or other causes. Eczema typically causes damage to the skin surface, leading to peeling on the sides of the nostrils and possibly causing papules or blisters. Patients are advised to use topical medications such as Qishen Lian eczema ointment, Erfu Kang lotion, or danshen phenol ointment under a doctor’s supervision to relieve symptoms.

In daily life, it is recommended to drink plenty of warm water and consume more vitamin-rich fruits such as oranges, grapes, and pomegranates, while minimizing intake of spicy foods like chili peppers and scallions, which may help improve skin dryness.
