Once the sensitivity occurs, it is inevitable to use hormone and antibiotic ointment for treatment. Hormone ointment will make the skin thinner and the barrier will be worse. Antibiotic ointment is prone to drug resistance, so it should be avoided as much as possible. [0004] At present, there are variou...
