Eczema can be self-healing or recurrently persistent without treatment, and the specific direction of development needs to take into account the specific condition and individual differences. Eczema is an inflammatory skin reaction caused by a variety of internal and external factors with a pronounced tendency to exude, mostly accompanied by pruritus. It varies widely depending on the etiology. For example, dry eczema in children is often caused by dry weather in autumn and winter, the thin and tender skin of children, poor water retention and lack of emolliency. For mild cases of dry eczema, when the temperature rises and the humidity of the air increases, it will naturally ease, and as children get older, the skin stratum corneum thickens and its ability to lock in water increases, it can also stop flare-ups. However, for atopic dermatitis, which is a kind of eczema with a large genetic correlation with allergies, can attack in any season, in infants, children, adolescents and adults, with different clinical manifestations, such as facial eczema in infancy, hypertrophy and dryness in the post-ear fissure or joint fossa of the extremities in childhood, such eczema is easy to delay the disease without treatment, making it more difficult to treat, and the prognosis is relatively poor, requiring active therapeutic intervention. In summary, eczema is a more general concept, and without treatment there is the possibility of self-healing, but also the risk of aggravation. The actual condition needs to be judged according to the condition, and it is recommended to seek medical attention early for a clear diagnosis, and then make a decision on whether to treat the condition.
