Dyshidrotic eczema, also known as pompholyx, is a type of eczema that affects the hands and feet. It causes small, fluid-filled blisters on the palms, fingers, and soles, which can be itchy, painful, and disruptive. Understanding what causes this condition and how to manage it can help reduce flare-ups and improve skin comfort.
What Causes Dyshidrotic Eczema
While the exact cause remains unknown, several factors are known to trigger or worsen dyshidrotic eczema. Identifying and avoiding personal triggers can reduce flare-ups:
Stress and emotional factors: Physical or emotional stress can trigger outbreaks, particularly during busy periods or major life changes.
Allergic reactions: Contact with metals like nickel (found in jewellery or coins), certain foods, or skincare products may cause flare-ups in sensitive individuals.
Seasonal changes: Many people notice symptoms worsen during spring and summer months when humidity levels change and allergens are more prevalent.
Excessive moisture or sweating: Prolonged exposure to water, frequent handwashing, or sweaty conditions can irritate the skin and trigger blisters.
Symptoms of Dyshidrotic Eczema
Dyshidrotic eczema tends to occur in cycles, with symptoms flaring up and then gradually resolving. Common signs include:
Small, deep blisters: Tiny, fluid-filled bumps appear on the sides of fingers, palms, or soles of feet, often feeling itchy or burning.
Intense itching and discomfort: Itchiness can be severe, especially at night, and may interfere with sleep or daily activities.
Skin peeling and cracking: After blisters heal, the skin often becomes dry, flaky, and may develop painful cracks or fissures.
Redness and swelling: The surrounding skin becomes inflamed, appearing red or darker than usual, with noticeable swelling around the blistered areas.
Dyshidrotic Eczema Treatment
Treatment focuses on relieving symptoms, promoting skin healing, and reducing the frequency of flare-ups. A combination of approaches may be used:
Topical treatments: Anti-inflammatory creams or ointments are typically prescribed to reduce redness, itching, and swelling during active episodes. These are applied to affected areas once or twice daily during flare-ups and tapered off as symptoms improve.
Oral antihistamines: Antihistamines may be recommended to help control itching, particularly at night. They can support better sleep and reduce scratching that might aggravate blisters or lead to skin breakdown.
Cool compresses: Applying cool, damp cloths to the affected areas several times a day can help soothe burning and itching, especially during the blistering phase. This also reduces inflammation and discomfort without irritating the skin.
Phototherapy: In more resistant cases, light-based therapy may be considered. Controlled ultraviolet (UV) light exposure helps calm inflammation and improve skin healing, especially when topical treatments have not been effective.
Systemic medications: For severe or recurrent dyshidrotic eczema, oral or injectable medications that target the immune response may be necessary. These are prescribed when symptoms are not controlled with creams or light therapy alone.
Patch Testing: If flare-ups are suspected to be triggered by allergic reactions, especially to metals like nickel or cobalt, your dermatologist may recommend patch testing. Identifying and avoiding specific allergens can play a crucial role in long-term control.
When to Seek Medical Advice
While many people can manage dyshidrotic eczema with self-care, there are situations where consulting a dermatologist in Singapore eczema specialist is important. Persistent itching, painful blisters, or recurrent flare-ups may indicate the need for professional evaluation and tailored treatment to restore skin health and prevent complications.
Persistent or worsening symptoms: If blisters don’t improve after two weeks of treatment, or if they become more frequent or severe over time.
Signs of infection: Look for increased redness, warmth, pus, red streaking, or fever, which may indicate bacterial infection requiring antibiotic treatment.
Conclusion
Dyshidrotic eczema can be uncomfortable, but with the right skincare, trigger avoidance, and timely treatment, many people are able to reduce flare-ups and improve their skin condition.
If symptoms persist or affect your quality of life, consult a dermatologist for a personalised care plan.
