Eczema is one of the common problems that babies have that is annoying and easily recurring. As autumn progresses and the weather becomes dry, babies can easily get eczema if they are not careful at this time. Eczema is a persistent problem that often flares up when you are not careful. Eczema is more prevalent in babies before they are two years old. So what is eczema? How should parents deal with eczema to keep their baby’s skin healthy? The characteristics of infant skin Dermatologists often compare the structure of the human epidermis to a brick wall. The outermost layer of the epidermis is the stratum corneum, the keratin-forming cells are like bricks, and the lipids between the cells are like mortar, which together form a stable skin barrier, a structure known as the “brick wall structure” that helps the body fight against harsh external environments such as dryness. Compared with adults, the skin structure of infants and young children is not yet well developed, the thickness of skin stratum corneum and epidermis are significantly lower than that of adults, and keratin-forming cells are also small, which means that the bricks are small and the number of layers of bricks is small; the lipid content of infant skin is lower than that of adults, which means that the wall is thin and the mortar is not strong. Therefore, the skin barrier function of infants and young children is incomplete, and the skin moisture is easily lost. These characteristics make babies more prone to various skin problems, the most common of which is eczema. What is “Eczema” Eczema (Eczema) is an inflammatory skin reaction caused by a variety of internal and external factors that itch intensely. It typically presents as red, papular, rough, flaky skin with oozing crusts and abnormal itching. The pathogenesis of eczema is still unclear and is currently believed to be the result of a combination of internal and external factors. However, pediatric dermatologists believe that in infancy and early childhood it is mainly due to skin barrier dysfunction, which in turn leads to immune abnormalities. How parents should respond The skin is the body’s barrier, there are many cracks when the skin is dry, poor skin barrier function, external factors can easily stimulate the skin, leading to eczema. We believe that to deal with eczema, 60% depends on emolliency and 40% requires medication. The clinical use of emollient cream is dimethylsilicone cream, also known as silicone cream No. 1, which is commonly known as silicone cream, is a medical emollient cream made by the First Children’s Institute. The most common is lack of lipid eczema, also called dry eczema. If the baby’s skin is dry, rough and itchy, parents just need to moisturize more, repair the skin barrier and keep the skin smooth and moist to achieve the therapeutic effect. For the sensitive skin of eczema babies, proper skin care is very important. In addition to the dry season we mentioned, we should also pay attention to the baby’s bathing habits, to ensure that the appropriate water temperature (no more than 39 degrees Celsius), every 1-2 days to take a bath, each time the time control in 5-10 minutes, choose hypoallergenic non-irritating body wash, after the bath, with soft, absorbent gauze or cotton bath towels to dry the baby’s body, and then immediately apply foam emollients all over the body. Baby’s clothing should also be pure cotton, loose, do not wear too much, indoor temperature to 20 ℃ – 24 ℃, 40% – 60% humidity is appropriate.
