The Bottom Line

Dyshidrotic eczema causes sudden, intensely itchy blisters on the palms, sides of fingers, and soles of the feet. It accounts for about 5–10% of all eczema cases and tends to come and go in flares lasting 2–4 weeks. Common triggers include nickel, stress, certain allergens, and damp conditions at work. With the right treatment plan and trigger management, most people can significantly reduce how often flares occur.

What Is Dyshidrotic Eczema?

Dyshidrotic eczema (also called pompholyx, vesicular hand dermatitis, or dyshidrosis) is a recurring skin condition that causes small, fluid-filled blisters on the palms, sides of the fingers, and soles of the feet. The blisters are usually 1–3 mm in size and can be intensely itchy or cause a burning sensation.

Despite its name, dyshidrotic eczema has nothing to do with sweating. The name comes from an old, now-disproven theory. The actual cause involves a combination of immune system sensitivity, a weakened skin barrier, and certain triggers — especially nickel, stress, and contact with irritants.

Dyshidrotic eczema represents about 5–10% of all eczema and around 20% of hand eczema cases seen by dermatologists. It can affect people of any age but peaks between ages 20 and 40.

Signs and Symptoms

  • Sudden appearance of small, deep-seated, clear blisters on the palms, fingers (especially the sides), and/or soles
  • Intense itching or burning before or alongside blisters
  • Blisters dry up after 2–4 weeks, leaving dry, cracked, peeling skin
  • Skin may become thickened or cracked between flares
  • Secondary infection (yellow crusting, increased pain) can develop if blisters are scratched open
  • Flares may recur monthly or several times a year

What Causes Dyshidrotic Eczema?

The exact cause varies from person to person, but research points to several key factors:

  • Nickel sensitivity: Nickel in food (chocolate, nuts, soy, shellfish) or contact with nickel-containing objects (jewelry, belt buckles, coins) triggers flares in 40–50% of nickel-sensitive individuals.
  • Stress: Emotional stress is one of the most commonly reported triggers.
  • Atopic history: About 40–60% of patients have a personal or family history of asthma, allergies, or eczema.
  • Occupational exposures: Healthcare workers, food service workers, cosmetologists, and metalworkers face higher risk from repeated contact with water, chemicals, and irritants.
  • Fungal infections: Active athlete's foot can trigger dyshidrotic eczema flares on the hands through an immune reaction.
  • Seasonal factors: Flares often peak in spring and summer in some patients, and in winter for others.

Treatment Options

  • Topical corticosteroids: Mid- to high-potency steroid creams applied during flares are the main treatment to reduce inflammation and itching.
  • Topical calcineurin inhibitors: Tacrolimus or pimecrolimus as non-steroid alternatives, especially for long-term use or thin skin areas.
  • Soaking and wet wraps: Cool water soaks help soothe itching; wet wraps with steroid cream can speed healing of active blisters.
  • Antihistamines: Help with itch relief, especially at night.
  • Phototherapy (PUVA or UVB): Effective for recurrent or severe dyshidrotic eczema that doesn't respond to steroids.
  • Systemic treatments: Oral corticosteroids for severe flares; dupilumab (a biologic) is showing promise in research studies.
  • Trigger avoidance: If nickel is a trigger, a low-nickel diet and avoiding nickel contact can reduce flare frequency significantly.

When to See a Dermatologist

  • Blisters are severe, cover large areas, or are very painful
  • Signs of skin infection develop (yellow crusting, increased warmth, pus)
  • Flares are happening frequently and affecting your ability to work or do daily tasks
  • Over-the-counter treatments are not providing enough relief
  • You want to identify your specific triggers through allergy patch testing

Frequently Asked Questions

Is dyshidrotic eczema contagious?

No. Dyshidrotic eczema is an immune-mediated inflammatory condition — it is not caused by an infection and cannot spread from person to person.

What foods should I avoid if I have dyshidrotic eczema?

If you are sensitized to nickel, a low-nickel diet may help reduce flares. High-nickel foods include chocolate, nuts, oats, soy, shellfish, and whole grains. However, dietary changes should be guided by a dermatologist or allergist based on your specific test results.

How long do flares last?

Most flares last 2–4 weeks. The blisters form, then dry up and leave behind peeling, cracked skin. With proper treatment, flares often resolve faster. Between flares, daily moisturizing and trigger avoidance help extend the time between episodes.

Can dyshidrotic eczema go away permanently?

For some people, flares become less frequent over time — especially when triggers are identified and managed. For others, it is a lifelong condition requiring ongoing management. Many patients experience long periods of remission with the right treatment plan.
