👋 “What are the symptoms of hand eczema?”
💊 “What should I do if I develop hand eczema?”

If you are troubled by a skin condition affecting your hands, you are not alone.

Hand eczema is a skin condition in which the hands become rough due to a weakened skin barrier function.

🔍 What is hand eczema?

Hand eczema is a skin condition characterized by cracked skin and the formation of small blisters on the hands.

Excessive hand washing and exposure to detergent ingredients can strip the skin of its moisturizing components, leading to a weakened skin barrier function and the development of hand eczema.

❓ Is stress related to hand eczema? Causes explained

The cause of hand eczema is skin dryness leading to a weakened skin barrier function. There is no established link with stress.

The skin on the hands and fingers has a thicker stratum corneum to help withstand external irritation.

However, frequent wet work or prolonged contact with detergents and similar substances can cause moisture to be lost from the skin if not properly cared for afterward.

When the skin barrier function is compromised, the skin becomes more vulnerable to external irritation, leading to symptoms such as cracking and blisters.

In addition, when the skin loses moisture and is subjected to various forms of irritation, the stratum corneum loses its elasticity and cracks. To help prevent hand eczema, it is important to make a habit of minimizing irritation to the fingertips on a daily basis.

😖 Does hand eczema cause itching? Symptoms explained

⚠️ Main symptoms of hand eczema

• 💧 Dry hands
• 😫 Itching
• 🩹 Peeling skin
• 🔴 Redness
• 😣 Swelling
• 💦 Blisters
• 💔 Cracked skin
• 🩸 Chapped skin (deep fissures)

In some cases, deep cracks may cause pain or lead to a bacterial infection.

🔬 How is hand eczema diagnosed?

When hand eczema is suspected, no special examination or tests are typically required.

However, if tinea (athlete’s foot of the hand) is suspected despite symptoms resembling rough skin, a small sample of skin may be collected for testing.

💊 How is hand eczema treated?

The primary treatment for hand eczema is applying a topical steroid medication two to three times a day.

Topical steroid medications may help reduce inflammation and calm redness in the affected area.

⚠️ Important point: Even if redness and itching improve, stopping the topical steroid medication too soon may result in a quick recurrence, so continue applying it until symptoms resolve.

In addition, since hand eczema is triggered by dry skin, moisturizers may also help relieve symptoms.

Continuing to apply a moisturizer even after redness and itching have subsided may help reduce the likelihood of recurrence.

🛒 What over-the-counter medications may help with hand eczema? Hand cream effects also explained

For hand eczema, over-the-counter topical steroid medications may also be helpful. Addressing symptoms early is important to avoid scratching, which can spread inflammation.

If cracking is severe, a mild ointment-type topical steroid is generally more appropriate.

❌ Hand cream alone cannot treat hand eczema!

Hand eczema cannot be treated with hand cream alone, so please be aware of this. Hand cream is a moisturizer, not a therapeutic medication.

Hand eczema involves “inflammation”, not merely dry skin, so calming the inflammation takes priority over moisturizing.

🛡️ How can hand eczema be prevented?

✨ 3 prevention methods you can start today

• 🧤 Wear gloves when doing wet work
• 🧴 Use low-irritant detergents
• 💧 Keep the skin moisturized

The primary cause of hand eczema is a weakened skin barrier function due to skin dryness.

Applying a moisturizer or hand cream after wet work or hand washing, when the hands are prone to drying out, may help reduce the risk.

People who frequently handle water in their daily work or household tasks are more susceptible to chronic hand eczema, so maintaining consistent fingertip care as part of your daily routine is important.

🔬 Detailed pathology and mechanisms of hand eczema

🧱 How the skin barrier function works in detail

To understand hand eczema more deeply, let us first explain the skin barrier function. Healthy skin plays an important role in protecting the body from external irritants and preventing foreign substances from entering.

The stratum corneum, the outermost layer of the skin, is composed of corneocytes and intercellular lipids. This structure is often compared to “bricks and mortar”. The corneocytes act as the bricks and the intercellular lipids as the mortar, together blocking external irritants.

When hand eczema develops, these intercellular lipids are lost, creating gaps between the corneocytes. As a result, moisture evaporates more easily and external irritants can penetrate into the skin more readily.

⚡ The inflammatory process

The inflammatory reaction in hand eczema is triggered by a complex immune mechanism. When the skin barrier function is compromised, substances that would normally be unable to penetrate reach the interior of the skin, and immune cells recognize these as foreign bodies.

At this point, Th1 and Th2 helper T cells are activated, releasing pro-inflammatory cytokines such as interleukins. These substances cause vasodilation, increased vascular permeability, and infiltration of inflammatory cells, resulting in symptoms such as redness, swelling, and itching.

📊 Detailed classification and characteristics of hand eczema

👆 Contact dermatitis type

The contact dermatitis type of hand eczema develops upon contact with specific substances. This type is classified into two subtypes: irritant contact dermatitis and allergic contact dermatitis.

🔵 Irritant contact dermatitis

This type is caused by chemical irritants and can occur in anyone exposed to a sufficient concentration or duration of contact. Common causes include detergents, soaps, alcohol-based disinfectants, and organic solvents. Symptoms are limited to the area of contact and may appear even on first exposure.

🔴 Allergic contact dermatitis

This type is caused by an allergic reaction to specific substances. Common causative substances include nickel, chemical compounds in rubber products, fragrances, and preservatives. Once sensitization has occurred, even minimal contact can trigger symptoms, which may spread beyond the area of contact.

💦 Pompholyx (dyshidrotic eczema)

This is a type of hand eczema in which numerous small blisters form on the palms and sides of the fingers. It is thought to involve abnormal function of the sweat glands. It tends to worsen in spring and summer and is more common in people with hyperhidrosis.

The blisters are clear and cause peeling when they rupture. Intense itching is often present, and there is also a risk of secondary infection.

⏰ Chronic eczema type

When hand eczema persists over a long period, the skin becomes thickened and develops a rough texture. This is referred to as the chronic eczema type. The skin surface hardens, making deep fissures and cracks more likely to form.

At this stage, ongoing inflammation means treatment takes longer, and recovery may take months to years in some cases.

👨‍⚕️ Characteristics of hand eczema by occupation and age

🏥 Hand eczema in healthcare workers

Those who work in healthcare settings are among the most susceptible occupational groups due to frequent hand washing and disinfection. Since the spread of COVID-19 in particular, enhanced infection control measures have led to a notable increase in the incidence of hand eczema.

💡 Characteristics of hand eczema in healthcare workers:

• 💧 Chemical irritation from alcohol-based disinfectants
• 🔄 Dozens of hand washings and disinfections per day
• 🧤 Allergic reactions from rubber gloves
• 📉 Significant impact on work performance

✅ Recommended measures: Use of alcohol-free disinfectants, wearing cotton gloves under rubber gloves, and intensive skin care after work are recommended.

🍽️ Hand eczema in food service workers

Those working in the food service industry are also at high occupational risk for hand eczema, as they are constantly in contact with water and detergents through dishwashing, cooking, and cleaning tasks.

⚠️ Characteristics of hand eczema in food service workers:

• 🌡️ Excessive removal of sebum by hot water
• 🧪 Exposure to strong detergents and bleach
• 🍋 Irritation from food ingredients (citrus fruits, spices, etc.)
• ⏰ Long working hours with limited break time

💇 Hand eczema in hairdressers and barbers

Hairdressers and barbers are prone to hand eczema because they regularly come into contact with chemical substances such as perm solutions, hair dye, and shampoos.

🔍 Key points to be aware of:

• 🎨 Allergic reactions to paraphenylenediamine (a component of hair dye)
• 💨 Irritation from ammonia-based perm solutions
• 💦 Extended work in wet conditions
• ✂️ Minor skin injuries during cutting

🏠 Hand eczema in homemakers

Wet work in household chores is the main cause. Hand eczema tends to become chronic due to daily housework such as laundry, dishwashing, and cleaning.

📋 Characteristics of hand eczema from housework:

• 📅 Continuous daily irritation
• 😔 Tendency to downplay symptoms, leading to delayed treatment
• 🔄 Environmental factors that make it difficult to pause housework
• 😰 Worsening of symptoms due to stress

👶 Hand eczema in children

Hand eczema in children has different characteristics from that in adults. Because children’s skin is thinner and more sensitive, even mild irritation can trigger inflammation, and symptoms may worsen rapidly.

👧 Characteristics of hand eczema in childhood:

• 🩺 High association with atopic dermatitis
• 😖 Symptoms tend to worsen due to scratching behavior
• 💊 Caution required when using topical steroid medications
• 🏫 Impact on school life (swimming lessons, lunch duty, etc.)

👴 Hand eczema in older adults

Sebum production decreases with age, making older adults more susceptible to hand eczema. In addition, because skin regeneration capacity is reduced, healing tends to take longer.

⚠️ Points to note for hand eczema in older adults:

• 🩹 Increased risk of injury due to skin thinning
• 💊 Need to check for interactions with other medications
• 🧠 Difficulty maintaining treatment due to cognitive decline
• 😢 Worsening of symptoms due to social isolation

📈 Severity classification and stepwise treatment of hand eczema

🟢 Mild (Grade 1)

✅ Symptom characteristics

• 💧 Mild dryness and redness
• 😊 Itching is present but does not significantly interfere with daily life
• 🩹 Mild peeling
• ✨ No blister formation

💊 Treatment approach

At the mild stage, the focus is first on thorough moisturizing care and removal of irritating factors. A weak topical steroid (weak to medium class) is applied thinly once or twice daily to the affected area.

The treatment period at this stage is generally around 1–2 weeks, and improvement may be expected within a relatively short time with appropriate treatment.

🟡 Moderate (Grade 2)

⚠️ Symptom characteristics

• 🔴 Moderate inflammation and swelling
• 😣 Itching is severe and interferes with daily life
• 💦 Formation of small blisters
• 💔 Mild cracking

💊 Treatment approach

For moderate cases, a medium to strong class topical steroid is used. It is applied two to three times daily, with the potency gradually stepped down as symptoms improve.

Combined use of a moisturizer is essential, with appropriate moisturizing applied before and after topical steroid application. Treatment typically requires around 3–6 weeks.

🔴 Severe (Grade 3)

🚨 Symptom characteristics

• 😰 Intense inflammation and swelling
• 😫 Severe itching that disrupts sleep
• 💦 Formation of numerous blisters
• 💔 Deep cracks and fissures
• ⚠️ High risk of secondary infection

💊 Treatment approach

For severe cases, a strong to very strong class topical steroid is used. Oral antihistamines may also be combined as needed to help control itching.

If secondary infection is suspected, topical or oral antibiotics may be considered. Treatment of severe cases may require two to three months or more.

🔍 Differential diagnosis: distinguishing hand eczema from similar conditions

🦠 Differentiating from tinea manuum (hand ringworm)

Tinea manuum is a condition caused by a fungal (mold) infection and closely resembles hand eczema in its presentation, making differential diagnosis important.

🔍 Characteristics of tinea manuum

• 🖐️ Symptoms often appear on only one hand
• 🦶 Often accompanied by tinea pedis (athlete’s foot)
• 💊 Responds to antifungal medication
• 🔬 Fungal elements detected on KOH examination

💡 Key differentiating features

Hand eczema typically presents on both hands, whereas tinea manuum often begins on one hand. In addition, most patients with hand eczema do not have tinea pedis, whereas tinea manuum is frequently associated with concurrent athlete’s foot.

⚡ Differentiating from palmoplantar pustulosis

Palmoplantar pustulosis is a chronic inflammatory condition characterized by numerous pustules on the palms and soles. Differential diagnosis is necessary because it resembles the pompholyx type of hand eczema.

🔍 Characteristics of palmoplantar pustulosis

• 💧 Characterized by sterile pustules
• 🤲 Symptoms appear symmetrically
• 🦷 Associated with focal infections (tonsillitis, periodontitis, etc.)
• 🦴 May be accompanied by joint symptoms

🩺 Hand eczema associated with atopic dermatitis

Hand eczema occurring in patients with atopic dermatitis is characterized by greater treatment resistance and a higher tendency to recur compared with ordinary hand eczema.

🔍 Characteristics of hand eczema associated with atopic dermatitis

• 🩹 Atopic symptoms also present in other areas (antecubital fossa, popliteal fossa, etc.)
• 📊 Elevated IgE levels
• 👨‍👩‍👧 Often a family history is present
• 🌼 Sensitization to environmental allergens

💡 Current treatment options for hand eczema

🧪 Topical calcineurin inhibitors

Topical calcineurin inhibitors such as tacrolimus ointment and pimecrolimus cream are gaining attention as treatment alternatives to topical steroids.

✨ Characteristics of topical calcineurin inhibitors

• ✅ Less likely to cause skin atrophy, a side effect associated with steroids
• ⏰ Suitable for long-term use
• 👤 Can be used on sensitive areas such as the face and genitals
• ⚠️ A temporary sensation of irritation may occur at the start of treatment

💊 Topical JAK inhibitors

Topical JAK (Janus kinase) inhibitors are a relatively recent treatment option. By directly inhibiting inflammatory signaling pathways, they may help control symptoms.

🌟 Advantages of topical JAK inhibitors

• ⚡ Relatively rapid onset of action
• ✅ Lower risk of steroid-related side effects
• 🛡️ Favorable safety profile for long-term use
• 💪 May also be considered for treatment-resistant cases

☀️ Phototherapy (excimer light / narrowband UVB)

Ultraviolet-based treatment that may be particularly helpful for chronic or treatment-resistant hand eczema cases.

💡 Excimer light therapy

Ultraviolet light at a wavelength of 308 nm is directed at the affected area to help suppress inflammation. This approach has the advantage of minimizing impact on healthy skin while targeting the affected area.

💡 Narrowband UVB therapy

This treatment uses ultraviolet light at a wavelength of 311 nm with a full-body phototherapy device. It may be selected when the hand eczema is widespread, or when other areas of skin inflammation need to be treated simultaneously.

💉 Biologics

For hand eczema associated with severe atopic dermatitis where conventional treatments have not provided sufficient relief, biologics may be considered in some cases.

💊 Dupilumab (Dupixent)

This is an antibody medication that inhibits the IL-4 and IL-13 receptors, targeting the underlying inflammatory mechanisms in atopic dermatitis. As part of atopic dermatitis management, improvement in hand eczema may also be expected.

⚠️ Complications of hand eczema and how to manage them

🦠 Secondary bacterial infection

When the skin barrier function is compromised by hand eczema, the risk of bacterial infection increases. Infections caused by Staphylococcus aureus and Streptococcus are particularly common.

🚨 Symptoms of infection

• 💧 Discharge of pus from the affected area
• 🔥 Intense pain or sensation of warmth
• 🔴 Spreading redness
• 🤒 Fever or swollen lymph nodes

💊 Treatment

If a bacterial infection is confirmed, topical or oral antibiotics are used. In severe cases, inpatient treatment may be required.

🦠 Herpetic whitlow

This is a complication that occurs when herpes virus infects the affected area of hand eczema. It is seen particularly among healthcare workers and those who care for young children.

🔍 Symptom characteristics

• 😖 Blisters accompanied by intense pain
• 🤒 Fever and general malaise
• 💢 Swollen lymph nodes
• 🔄 Tendency to recur

🚨 Eczema herpeticum (Kaposi’s varicelliform eruption)

This is a serious complication in which herpes virus spreads extensively in patients with hand eczema associated with atopic dermatitis.

⚠️ Symptoms and management

Numerous blisters merge to form erosive areas. As the patient’s general condition may deteriorate, urgent hospitalization for intravenous antiviral therapy is required.

🤰 Managing hand eczema during pregnancy and breastfeeding

👶 Treatment options during pregnancy

During pregnancy, the choice of treatment requires careful consideration of potential effects on the fetus.

✅ Treatment options that may be used

• 💊 Weak to moderate topical steroids (for short-term use)
• 💧 Moisturizers (no restrictions)
• 🧤 Physical skin care measures (e.g., wearing gloves)

⚠️ Treatments requiring caution

• 💊 Strong topical steroids (avoid prolonged use)
• 🧪 Topical calcineurin inhibitors (use with caution especially in the first trimester)
• 💊 Oral medications (including antihistamines — consult your physician)
