The treatment method after facial allergy is related to the clinical symptoms after facial allergy, and the methods chosen are different for different symptoms. There are many symptoms of facial allergy, such as erythema, papules, dryness, tightness, erosion, oozing, itching and peeling. If there are simple erythema and papule-like changes, you can choose to use hyaluronic acid gel with compound snake fat ointment for treatment. If there is simple dryness and tightness you can choose to use glycerin for application with vitamin E cream. In case of localized vesicles and exudative changes, it is recommended to use saline-soaked sterile gauze applied wet to the epidermis of the wound surface 1-2 times/day for 20 minutes each time. Soon the vesicles and exudative changes will dry up, together with the use of human-like collagen milk. If local itching is evident and accompanied by peeling, it is recommended to opt for topical application of hyaluronic acid gel along with oral antihistamines such as cetirizine tablets or loratadine tablets.
