Blisters on the lips can have multiple causes, with herpes simplex virus infection being the most common. This virus is tricky and tends to appear when our immune system is weak, such as during a cold, times of high stress, or fatigue. The blisters often come with tingling, itching, or even a burning sensation, causing discomfort.
Apart from viral infections, blisters on the lips can also result from allergic reactions. In daily life, we may encounter allergens such as certain foods, cosmetics, or ingredients in toothpaste. Allergic reactions can lead to blisters on the lips, accompanied by swelling and itchiness. If you notice blisters on your lips every time you use a particular product, consider it might be an allergic reaction.
Weather changes are another factor. Dry and cold weather can cause lips to lose moisture, becoming chapped. When this happens and the lips are further exposed to bacterial infection, blisters may appear. Keeping lips moisturized is crucial, especially in windy seasons, and lip balm can be used for protection. If blisters on the lips recur or the symptoms are severe, it is recommended to seek medical attention promptly. Doctors can determine the specific cause through examination and provide targeted treatment plans.
Generally, herpes simplex can be treated with antiviral medications, while allergic reactions require identifying the allergen and avoiding exposure. In daily life, maintaining good hygiene habits and avoiding sharing towels, utensils, and other items can effectively prevent the spread of viruses. Dietarily, consuming foods rich in vitamins can enhance immunity and help reduce the chance of lip blisters. Hope these tips help you better protect your lip health.
