Repeated face allergies can be treated by detaching allergens, general treatment and medication. 1. Disengage from allergens: For patients who are always allergic to allergens, they can go to the hospital to find out the allergens, so as to avoid re-exposure in the future. 2. General treatment: for allergic patients, usually pay attention to the use of mild cleansing milk to clean the face, and when the allergy attack, pay attention not to scratch the local area, or the use of irritating skin care products, cosmetics and so on. 3. Medication: For those with obvious local itching, oral antihistamine preparations such as loratadine can be prescribed to alleviate the symptoms, and topical calcineurin inhibitors such as tacrolimus, pimecrolimus, or glucocorticoids such as hydrocortisone ointment can be used to fight inflammation and promote lesion regression. For patients with recurrent allergic reactions to the face, it is recommended that the patient go to the dermatology department of a regular hospital and be actively treated under the guidance of the doctor.
