People with eczema have a weakened skin barrier, which can lead to a variety of skin issues. Eczema can occur anywhere on the body and may cause your skin to feel dry, itchy, and uncomfortable, with scaly, rough patches. The dryness that’s often associated with eczema can also lead to scratching and rubbing, which may result in swollen skin rashes. Although it’s most often developed in childhood, eczema affects people of all ages—including 16.5 million adults in the United States.4
