What Is Eczema?
Eczema, also known as atopic dermatitis, is a disease that causes the skin to become itchy and red. It is prevalent in children but may affect people of all age groups. Eczema is a chronic condition and is likely to flare frequently. Symptoms may be accompanied by hay fever or asthma. Currently, there is no cure for eczema. But some self-care measures and treatment options may help ease the symptoms and prevent possible flare-ups in the future. 
What Are Dust Mites?
Dust mites are microscopic pests that can be commonly found in blankets, clothes, beds, couches, carpets, and other common furnishings in the household. They tend to live in large groups. While dust mites do not bite humans, they may cause redness and itchiness on the skin.
Dust mites digest debris like skin scales, pollen, and dead insects as food. During this procedure, they make small droppings containing digestive enzymes, damaging and killing cells on the skin. In most cases, you cannot notice dust mites due to their small sizes. A few damaged cells are not a concern. But when these effects are significant, they would lead to the worst issues.
