What causes a white, peeling patch on the face?

A white patch with peeling on the face may be caused by seasonal dryness, sun exposure, seborrheic dermatitis, vitiligo, psoriasis, etc. Appropriate measures can be taken based on the underlying cause. Specific analysis is as follows:

1. Seasonal dryness: In winter or dry environments, the skin tends to lose moisture, leading to dryness and peeling, sometimes accompanied by mild hypopigmentation. It is recommended to use moisturizing creams or lotions, especially immediately after washing the face, to help lock in moisture.

2. Sun exposure: Prolonged exposure to strong sunlight may cause sunburn, manifesting as redness, peeling, and pigment changes. It is advised to avoid prolonged sun exposure during peak sunlight hours and to use sunscreen when going outdoors.

3. Seborrheic dermatitis: This is a common chronic superficial inflammatory skin condition that may also cause white patches and peeling on the face. It is recommended to follow medical advice and use medications such as compound dexamethasone cream, acetic acid dexamethasone cream, or halometasone cream to improve symptoms.

4. Vitiligo: Vitiligo is a common skin disorder characterized by loss of pigmentation, resulting in localized white patches on the skin, sometimes accompanied by peeling. It is recommended to take medications such as Qubai Babuqi tablets, Bailing tablets, or vitiligo pills under medical supervision to help relieve discomfort.

5. Psoriasis: Psoriasis is a chronic, recurrent, inflammatory skin disease. Although it rarely occurs on the face, it may still cause facial white patches and peeling. It is recommended to use medications such as desonide cream, tretinoin cream, or clobetasol propionate cream under medical guidance to alleviate symptoms.

If any abnormal conditions appear on the face, it is advisable to seek timely medical evaluation and treatment as directed by a healthcare professional.
