The drying up and crusting over of eczema is a sign of improvement. If the eczema patient had blisters before, the blisters will gradually dry up and crust over when they improve, and the other symptoms of the acute phase will gradually subside. When eczema improves, the first thing that happens is that the color changes from red to brown or dark red and then gradually to brown, which often indicates that the inflammation is in remission. Next, the eczema redness will gradually improve, the height of the rash will gradually flatten, and the blisters will dry up and crust over. If the skin was previously rough and flaky, it will also become smooth as it improves. At the same time, the patient will feel that the previous itching is more intense, scratching more frequently, while the itching gradually reduced, scratching frequency gradually reduced. Eczema patients should maintain a good mood, pay attention to keeping the skin clean and dry, try to avoid scratching, eat more fresh vegetables and fruits rich in vitamins, avoid spicy and stimulating food, and should not drink alcohol.
