Dyshidrotic eczema, also known as dyshidrosis, is a type of skin inflammation that appears on the hand and feet in the form of small liquid-filled blisters. In many cases, the condition is chronic, is not contagious, and can include outbreaks as well as periods of remission. Often, dyshidrosis is seasonal, causing more outbreaks during spring and summer.
The cause of this skin disorder is internal, meaning it originates within the body. In fact, it’s often associated with factors like stress and allergies. While it often appears for the first time in individuals between the ages of 15 and 30, it can affect people of any age or gender.
