Eczema is a relatively common clinical allergic skin disease, mainly divided into acute eczema, chronic eczema and so on. The process of eczema getting better is mainly the reduction of self-conscious symptoms, such as the gradual relief of itching; the color of the rash changes from bright red to dark red, and finally to dark brown until it disappears; the scope of the rash gradually decreases, and the area of patchy rash is reduced until it disappears. For acute eczema, the exudation gradually decreases, the blisters dry until they flake and the rash subsides. For chronic hypertrophic eczema, the rash gradually becomes thinner and flatter until it disappears, and the eczema should continue to consolidate treatment for a period after it improves to avoid recurrence.
