In addition to dietary factors, inhalants, such as pollen, dust, mites and bacterial and fungal infections of the body surface, changes in the living environment, and the various substances to which they are exposed may be common external causes of dry eczema.

Ice: Ice packs help relieve itchy skin caused by contact dermatitis. Pour milk into a glass of ice towel and let it sit for a few minutes. Pour this milk on a gauze pad or thin cotton cloth and apply to the itchy skin area for 2-3 minutes. Repeat this for 10 minutes. If this method does not work, you should see your doctor as soon as possible. 2. Beware of baby lotions: Baby lotions are not the best choice for treating eczema in children. These products contain high amounts of water, and when the water evaporates, it makes the skin drier and more itchy. 3, with warm water bath: dermatitis patients can take a bath, but need to wash with warm water, which can reduce the chance of infection and help soften the skin.

Hot compresses are not suitable for eczema. 4, the use of emollient products: after each bath, should be applied to the emollient lotion to retain moisture and prevent water loss. Be careful not to bathe too often.
