Facial allergy acne, mostly caused by consumption, contact or injection of allergens or allergen-containing substances, can mostly appear as inflammatory papules, which need to be actively treated with anti-allergy therapy. First of all, you need to stop using all skin care products that may cause facial allergy, isolate the allergen, and if necessary, go to the hospital for allergen testing; secondly, take oral anti-allergy medication under the guidance of a doctor, such as loratadine, epalrestin, levocetirizine hydrochloride, doxycycline enteric capsules, compound glycopyrrolate tablets, etc. Finally, according to the severity of the acne, under the guidance of the doctor, appropriate topical glucocorticoid cream, such as hydrocortisone, mometasone furoate cream, etc. for treatment. If the face is red and swollen or accompanied by certain inflammatory exudation, cold compresses of boric acid and saline can be used temporarily, together with red and blue light irradiation treatment. If it is accompanied by diffuse erythema, topical tacrolimus cream can be applied. However, attention should be paid to avoid long-term use of hormonal drugs and stop them immediately after the allergy subsides. In addition, you should do simple skin care, wash your face with water every day and avoid applying too many skin care products and cosmetics.
