What are the symptoms of lip vitiligo?
I. Local White Patches
1. Shape: Vitiligo on the lips usually leads to round or elliptical white patches on the lips, which gradually expand and form a sharp contrast with the surrounding normal skin color;
2. Border: Due to damage to melanocytes, they are unable to secrete melanin normally, resulting in white patches appearing on the lips. The hair on the white patches may also turn white. If the condition is severe, it can also change the surrounding skin and even affect the mucosal tissue around the mouth, leading to angular cheilitis;
3. Others: As the disease progresses, the color of the white patches may also change, from pale white or milky white in the early stage to porcelain white in the later stage.
II. Blurred Edges
As vitiligo is a chronic disease, it destroys local melanocytes after onset, resulting in blurred edges. The boundary between white patches and normal skin is not particularly clear.
III. No Subjective Symptoms
Most patients do not experience significant discomfort, but a small number of people may experience mild itching during onset, especially after exposure to sunlight, which may exacerbate the itching. Besides the above common symptoms, dryness at the affected site may also occur. It is recommended to seek medical attention promptly to avoid delaying the condition.
In daily life, it is important to avoid spicy and stimulating foods such as chili and Sichuan peppercorns, as well as smoking and alcohol consumption.
