Dyshidrotic eczema, also known as dyshidrosis or pompholyx, is a form of Eczema that causes small, itchy blisters and dry, irritated skin. It most often appears between the fingers, on the palms of the hands, and on the soles of the feet.
These blisters are filled with fluid and look like tiny, cloudy beads. They are usually about 1 to 2 mm wide, similar to the size of a pinhead. In some cases, several blisters can merge and form a larger one. As they heal and dry, the skin may become scaly, peel or crack.
Among people who have hand eczema, about 5% to 20% are affected by dyshidrotic eczema. While it can be uncomfortable, a healthcare provider can help diagnose the condition and guide you toward effective ways to manage and treat it.
The exact number of people affected by dyshidrotic eczema, also called pompholyx, is not clearly known. However, studies suggest that around 20% of people who undergo patch testing for hand dermatitis are diagnosed with dyshidrotic eczema. This condition can affect anyone, and it does not appear to be linked to a specific age group or gender.
Dyshidrotic eczema causes symptoms that may flare up and then improve. These flare-ups can last for several weeks. The symptoms mainly affect the skin and may include:
In more severe cases, the blisters can become larger and spread to the backs of the fingers, hands, or feet. However, they do not spread to other areas of the body.
The exact cause of dyshidrotic eczema is not known. Healthcare providers believe it happens due to a mix of genetics and environmental factors. If a close family member, such as a parent or sibling, has this condition, you may have a higher chance of developing it.
Certain triggers can also cause symptoms to flare up. These may include stress, allergens, or other environmental factors.
Many people have asked: Is dyshidrotic eczema contagious? The answer is no. You cannot catch it from someone else, and it does not spread through touch.
Getting an accurate diagnosis is important to confirm dyshidrotic eczema and rule out other skin conditions that may cause similar symptoms.
Dyshidrotic eczema is usually diagnosed through a physical examination and a review of your medical history. A healthcare provider examines the blisters and asks about your symptoms, flare-ups, and possible triggers.
In some cases, allergy testing or skin cultures may be performed. These tests help determine whether other skin issues, like allergies or infections, might be causing similar symptoms.
The severity of dyshidrotic eczema can be measured using a tool called the Dyshidrotic Eczema Area and Severity Index. This method is mainly used in research and clinical trials and is not commonly used in routine medical practice.

Knowing how to treat dyshidrotic eczema is key to managing flare-ups and keeping your skin healthy. Treatment focuses on reducing symptoms, preventing further irritation, and addressing any complications.
If you know what causes your flare-ups, such as a contact allergy, try to avoid it as much as possible. Limiting exposure to triggers reduces the likelihood of future episodes.
Emollients, also called medical moisturizers, are the first step in treatment. Use them regularly for both moisturizing and gentle washing. Soap can strip the skin of natural oils, so using an emollient soap substitute is recommended. Carrying a small dispenser of emollient for use during the day can help protect your hands, especially if frequent hand-washing is needed.
For severe flare-ups with weeping, oozing, or crusting, a potassium permanganate soak may be advised. This chemical comes in tablets, crystals, or solution and is for external use only. It is usually prescribed but can sometimes be purchased over the counter.
How to use safely:
Topical steroids are prescribed to reduce inflammation and help the skin heal. Because the skin on palms is thicker, stronger steroids are usually needed for adults, while children typically receive moderately potent creams.
If your blisters become sore, weepy, or develop yellow crusting, a bacterial infection may be present. A healthcare provider may prescribe oral antibiotics to treat the infection.
This approach—avoiding triggers, using emollients, treating inflammation with steroids, and addressing infections—helps manage dyshidrotic eczema and reduces the severity and frequency of flare-ups.
Eczema can appear in many forms, each with its own symptoms and triggers. Some of the most common types of eczema include:
Clinical trials are significant in advancing dermatology care because they help test potential new treatments and improve patient outcomes. These studies carefully evaluate the safety and effectiveness of investigational therapies. For instance, ongoing atopic dermatitis clinical trials are testing a study drug for moderate to severe cases, giving patients access to new treatment possibilities and expert care.

In conclusion, dyshidrotic eczema is a recurring skin condition that causes painful, itchy blisters on the hands and feet. While it is not contagious, proper diagnosis, trigger management, and consistent treatment can help reduce flare-ups and improve skin health.
Dyshidrotic eczema can be triggered by stress, excessive sweating, or contact with irritants such as soaps and certain metals like nickel or cobalt. Flare-ups often happen in warm weather or during allergy season and may be more common in people with other atopic conditions, such as hay fever.
Dyshidrotic eczema flare-ups usually last 2 to 4 weeks, but the condition is often chronic and can return with triggers like stress, sweat, or allergens. Some people have occasional episodes, while others experience frequent flare-ups, though proper management can help control symptoms.
Dyshidrotic eczema and herpetic whitlow can look similar because both cause blisters on the fingers, but they need very different treatments.
