Allergic redness and itching on the face may be a result of allergic dermatitis of the face. For this condition, local cold compresses with saline can be used temporarily, which can control the further development of erythema, flushing and itching on the face. You can also apply topical glucocorticoids, such as topical hydrocortisone butyrate cream and dinaide cream. In addition, oral antihistamines, usually second-generation antihistamines such as levocetirizine hydrochloride, loratadine, epinastine, etc., are required. If these lesions develop further and are accompanied by significant exudation, appropriate oral glucocorticoids, such as prednisone and dexamethasone, are also required.
