Redness and itchiness on the face is usually a sign of facial dermatitis and can be treated by applying a cold wet compress with saline or 3% boric acid solution.
If you cannot get relief, you should seek medical treatment promptly and follow the doctor’s instructions to use medication, never abuse it on your own. Usually, doctors recommend medications such as Denide cream and hydrocortisone butyrate cream, etc. Care should be taken not to use them for a long time, usually not more than a week of continuous use on the face.
