The treatment of face allergy with a layer of small rashes includes topical drug treatment, oral drug treatment and so on. 1. Topical medication: For allergy-induced rashes, glucocorticoid creams, such as mometasone furoate cream, or immunosuppressant creams, such as pimecrolimus cream, can be applied as prescribed by the doctor to inhibit the immune-inflammatory response. 2. Oral medication: For rashes that do not respond well to topical medications, you can take antihistamines such as loratadine tablets and cetirizine hydrochloride tablets orally as prescribed by your doctor to desensitize the skin. If you have a face allergic to a layer of small rashes, please go to the hospital in a timely manner, under the guidance of the doctor’s treatment.
