Sudden small blisters on the lips may be caused by improper cleaning around the lips, lipitis, herpes simplex and other reasons.
1. Improper cleaning around the lips: If you don’t pay attention to the cleaning around the mouth in your life, it is likely to cause clogging of the hair follicles on the lips and damage to the skin barrier, resulting in sudden small blisters on the lips.
2. Lipitis: when the lips are stimulated by spicy foods such as chili peppers and peppers, or when the outside world is exposed to strong sunlight, lipitis is likely to occur, and the inflammation can lead to sudden small blisters on the lips.
3. Herpes simplex: When the body’s immunity is reduced and the skin barrier function is impaired, it is easy to be infected with the herpes simplex virus. This can lead to the sudden appearance of small blisters on the lips.
There may be other conditions that may cause sudden blisters on the lips, so you can go to the hospital to complete the relevant examinations to clarify the situation and take appropriate measures.
