Dr. Wang Xiaoyan
Facial allergy is a common skin condition, usually caused by an abnormal immune response triggered when the facial skin comes into contact with certain allergens. These allergens may include foods, medications, cosmetics, seasonal factors (such as pollen, dust mites), and others. After coming into contact with an allergen, the immune system releases chemical substances that cause symptoms such as redness, swelling, itching, papules, and blisters on the skin. In addition, excessively cold or hot environments, long-term exposure to chemicals, or contact with irritating solutions may also trigger or worsen facial allergies.
To relieve symptoms of facial allergies, it is recommended to identify and avoid the allergen promptly, keep the skin clean and moisturized, and use antiallergic medications under a doctor's guidance. At the same time, it is important to avoid excessive rubbing or squeezing of the skin to prevent worsening of symptoms.
