Expanded facial allergies are mainly treated by applying topical as well as oral medications, and in the process of treatment, daily care should be taken. Excessive scope of facial allergy may cause obvious itching and other symptoms, which can be treated with topical medications such as glycerite lotion and tacrolimus ointment to improve the uncomfortable symptoms. It should also be treated with oral anti-allergy medication, such as cetirizine and loratadine, to reduce the allergic reaction and promote recovery. During treatment, allergens should be identified and avoided, and facial skin should be kept clean and dry, and cosmetics and irritating toiletries should not be used to prevent symptoms from worsening. When using medication, you need to follow the doctor’s instructions, do not use drugs indiscriminately.
