Facial dermatitis is a very broad concept, common causes include allergies, sunburn, infection, etc. After the red color of the dermatitis subsides, some of the drugs still need to be used for a period of time in order to consolidate the effect of the drug, anti-infective drugs may need to be reduced or stopped, as prescribed by the doctor. The red color of facial dermatitis has subsided, indicating that dermatitis has been controlled, but because dermatitis disease is prone to recurrence, generally pay attention to not stopping the drug before the complete cure, to prevent the disease from recurring and become more serious. And certain anti-infective drugs such as antibiotics may need to be stopped promptly after the infection is controlled. Patients should do a good job of self-management and daily care, use medication under the guidance of a doctor, and seek medical treatment promptly if uncomfortable symptoms occur.
