Face allergy can heal itself in a few days

Face allergy can heal itself in a few days, depending on the allergen causing the allergy and the severity of the skin lesions. In general, after identifying the allergen and removing the allergen, the symptoms are not very serious, and it can heal in about 1 to 2 weeks. If the allergen is more irritating, or the skin lesions are more serious, it is probably difficult to heal. The above health science popularization knowledge is for reference only. The specific situation needs to be examined in a regular hospital and judged by a professional doctor.
