Mild allergies on the face may only manifest as mild itching, or slight redness, etc. If it is not serious, the temporary use of saline cold compresses can greatly alleviate the symptoms, there is no need to use medication. However, if the itching or erythema produced by allergy does not subside in time, medication is also needed. You can choose oral antihistamines, such as levocetirizine hydrochloride or loratadine, which are second-generation antihistamines. For topical application, hydrocortisone butyrate cream or topical chlorcyclizine cream can be used as an anti-allergic treatment, and while using these medications, avoid eating spicy and stimulating foods.
