Eczema on the face that is rough to the touch and red when hot can be considered to have recurrence of eczema, which is related to a variety of internal and external factors, or redness and heat when accompanied by infection. Under the mutual influence of external factors such as food, animal hair or living environment (e.g. dryness, heat) and internal factors such as psycho-neurological factors and heredity, eczema can occur repeatedly in the organism. 1. If acute eczema occurs, pimples and blisters on the basis of erythema will appear on the face, hands, feet and other parts of the body, often with intense itching, and vesicles after scratching, and the face may be red and hot due to inflammation stimulation, and there is oozing. 2. The symptoms of redness and fever may also appear when accompanied by infection. When eczema appears on the face, it is recommended to seek timely medical treatment to relieve and eliminate clinical symptoms and prevent recurrence.
