If the lesions become smaller, lighter or darker in color, the flakes disappear and the itchiness of the skin is reduced after standard, scientific treatment, it is a sign that the eczema is beginning to subside. When acute eczema begins to subside, the original exudate is significantly reduced or stops oozing and becomes dry and crusty, or the crusted areas become harder and harder, or even the crusts form and fall off naturally. There is also a reduction in redness and swelling, and the itching disappears. The erythema or papules of subacute or chronic eczema gradually become darker or lighter in color, from bright red to dark red or brownish gray, then brown or light black, and as the eczema subsides, the color gradually lightens and fades until it disappears. After the eczema has subsided, treatment should continue to prevent it from coming back. The topical application of creams should continue to be used for about 2 days, diet can also eat more fruits and vegetables that clear heat and detoxify and drive away dampness, such as mung beans, lettuce, bitter gourd, mustard, etc. Avoid taking stimulating foods, avoid spicy foods, adhere to a relaxed state of mind and increase recreational activities as appropriate. In conclusion, when eczema, a common skin disease, begins to subside, there will first be a reduction in local skin wound exudation, local tissue swelling decreases, subsides, and then begins to crust off. This is a sign that eczema is starting to improve or even heal significantly.
