Causes and Triggers of Dyshidrotic Eczema

Dyshidrotic eczema, also known as pompholyx, is a frustrating and often recurring skin condition characterized by small, severely itchy blisters on the hands and feet. If you’ve experienced this ailment, you’ve probably also wondered what causes it and how to prevent flare-ups.

At Stone Oak Dermatology, board-certified dermatologist Dr. Linda J. Banta provides expert care and guidance for patients dealing with dyshidrotic eczema and other chronic skin disorders. She helps patients understand common triggers and risk factors so they can manage symptoms and reduce future outbreaks.

What Triggers Dyshidrotic Eczema?

Dermatologists have not identified a single cause of dyshidrotic eczema. However, they have pinpointed several possible triggers:

• Stress: Emotional stress is one of the most commonly reported triggers. Managing anxiety and daily stress can be crucial in controlling outbreaks.
• Allergies: Individuals with seasonal allergies or sensitivities to certain substances, such as nickel, cobalt, or chromium, may be more likely to develop dyshidrotic eczema.
• Sweaty Palms and Feet: Excess moisture, especially during warm weather or physical activity, can worsen symptoms.
• Skin Irritants: Harsh soaps, detergents, or exposure to cleaning products may irritate the skin and spark a flare-up.
• Fungal Infections: In some cases, athlete’s foot or other fungal infections act as a trigger.

Who Is Most at Risk?

You might be more likely to develop dyshidrotic eczema if:

• You have a personal or family history of eczema, allergies, or asthma.
• You work in environments that involve frequent hand washing or exposure to irritants (such as healthcare, cleaning, or food service).
• You live in a hot, humid climate or experience seasonal allergies.

What Can You Do About It?

While there’s no cure for dyshidrotic eczema, managing your environment and habits can reduce the frequency and severity of outbreaks:

• Keep your hands and feet cool and dry.
• Use gentle, fragrance-free skincare products.
• Wear gloves when handling cleaning agents or other potentially irritating substances.
• Moisturize regularly with dermatologist-approved products.
