Understanding the Different Types of Eczema 

Women with different types of eczema.

Eczema, a term that encompasses a range of persistent skin conditions, manifests in several distinct forms, including atopic dermatitis, contact dermatitis, dyshidrotic eczema, nummular eczema, seborrheic dermatitis, and stasis dermatitis.


In this article, we explore each of these types of eczema in detail, uncovering their specific symptoms, causes, and treatment strategies to provide a clearer understanding of this complex and often challenging skin condition.

Common Types of Eczema

Eczema, a group of conditions that cause skin inflammation and irritation of the skin, includes several common types, each with different characteristics and causes of eczema.

Atopic Dermatitis

This is the most common form of eczema, often starting in childhood. It’s characterised by dry, itchy skin and rashes on the face, inside the elbows, behind the knees, and on the hands and feet. It’s often associated with a family history of allergies or asthma.

Contact Dermatitis

This type of eczema occurs when the skin reacts to a substance it has come into contact with, resulting in a localised rash. There are two main types: irritant contact dermatitis (caused by chemicals or other irritating substances) and allergic contact dermatitis (triggered by an allergen). The hands are particularly prone to developing contact dermatitis.

Dyshidrotic Eczema

Dyshidrotic eczema is a skin condition where small, itchy blisters develop on the palms of the hands, the sides of the fingers, and sometimes on the soles of the feet. The cause is unknown, but it may be related to stress, allergies, damp hands and feet, or exposure to certain metals like nickel. The blisters can be painful and may cause the skin to flake or crack. It’s more common in adults under 40 and is not contagious.

Nummular Eczema

Nummular eczema, or discoid eczema, is a type of eczema that causes round, coin-shaped spots on the skin. These lesions can be itchy, red, and scaly, and sometimes they ooze fluid. It usually affects the arms, hands, legs, and torso, but can appear anywhere on the body. The exact cause of nummular eczema is unknown, but it may be triggered by factors like dry skin, environmental irritants, stress, and certain medications.

Seborrheic Dermatitis

Seborrheic dermatitis is a common skin condition that mainly affects the scalp, causing scaly patches, red skin, and stubborn dandruff. However, it can also develop on other oily areas of the body, such as the face, sides of the nose, eyebrows, ears, eyelids, and chest. The exact cause is not known, but it might be related to a type of yeast on your skin or having oily skin.

Stasis Dermatitis

Stasis dermatitis, also known as venous eczema, is a skin condition that typically occurs in the lower legs and is related to poor blood circulation. It’s often associated with venous insufficiency, where the veins in the legs struggle to return blood back to the heart. This can lead to blood pooling in the legs, causing pressure to build up. The signs and symptoms of stasis dermatitis can vary between individuals and may appear differently on lighter and darker skin tones. In lighter skin tones, you might see redness, swelling, itching, thin skin, and sometimes ulcers. In darker skin, the affected area might get darker, swell, feel heavy, become thick, and ulcers can also happen.

To manage symptoms effectively and prevent flare ups, it’s essential to understand the common types of eczema.

Symptoms and Diagnosis

Eczema symptoms can vary depending on the type and severity, but there are common signs to look for:

Common Symptoms

  • Itchiness: Often intense and persistent, it is a hallmark of most types of eczema.

  • Redness: Affected areas may appear reddened or inflamed.

  • Dry, Sensitive Skin: The skin may be excessively dry and prone to irritation.

  • Rashes: These can appear in specific areas, such as the inner elbows or knees, in atopic dermatitis or may be widespread.

  • Fluid-filled Blisters: Common in dyshidrotic eczema, these can be painful or itchy.

  • Scaly or Rough Patches: Particularly noted in seborrheic dermatitis, these patches can be oily or dry.

  • Swelling: Often seen in stasis dermatitis due to poor circulation.

Diagnosis

Diagnosis of eczema is primarily based on a physical examination and a review of personal and family medical history. There are no specific tests for eczema, but certain procedures can help differentiate it from other skin conditions:

Patch Testing

Commonly used to diagnose contact dermatitis by applying small amounts of various substances to the skin and observing reactions.

Skin Swab

Skin swabs may be used to rule out infection, especially if the eczema is severe or doesn’t respond to treatment.

Blood Tests

Blood tests can be helpful in identifying underlying conditions, such as allergies, that may contribute to eczema symptoms.

Skin Biopsy

Rarely needed but can be used to exclude other conditions with similar symptoms. Learn the differences between psoriasis and eczema.

A dermatologist or healthcare provider will consider the appearance of the skin and the history of symptoms. Since eczema can often be confused with other skin disorders, like psoriasis, a careful examination is essential for an accurate diagnosis.

Triggers and Prevention

Managing eczema involves understanding and avoiding triggers that can cause flare-ups or make eczema worse. Eczema affects each individual differently, and triggers can vary. However, there are some common ones to be aware of:

Common Triggers

  • Irritants: These include soaps, detergents, shampoos, disinfectants, and cleaning products that can irritate the skin.

  • Allergens: Pollen, dust mites, pet dander, mould, and certain foods are known for triggering hay fever and allergic reaction. They can also trigger eczema in susceptible individuals.

  • Microbes: Certain bacteria, viruses, or fungi can exacerbate eczema symptoms.

  • Hot and Cold Temperatures: Extreme temperatures, high and low humidity, and perspiration can all trigger eczema.

  • Stress: Emotional stress is a well-known trigger for eczema flare-ups.

  • Hormones: Hormonal changes, particularly in women during periods of menstruation or pregnancy, can impact eczema.

Prevention Strategies

While it’s not always possible to completely prevent eczema flare-ups, certain strategies can help manage and reduce their frequency:

Moisturise Regularly

Keeping the skin well-moisturised is key in managing eczema. Use fragrance-free moisturisers, preferably right after bathing, to lock in moisture.

Avoid Known Irritants

Identify and avoid soaps, detergents, and fabrics (like wool or polyester) that may lead to irritated skin.

Control Temperature and Humidity

Aim to keep your environment cool and humidified to prevent dry skin.

Stress Management

Practices like mindfulness, yoga, and meditation can help manage stress.

Diet and Nutrition

Pay attention to your diet; certain foods might trigger eczema in some people, so it’s best to stay away from known foods to avoid with eczema.

Gentle Skincare Routine

Use mild, fragrance-free cleansers and avoid scrubbing or drying your skin harshly.

Avoid Scratching

Scratching can exacerbate symptoms and lead to infection. Keep fingernails short and consider wearing gloves at night.

Wear Breathable Clothing

Choose clothing made from soft, breathable fabrics like cotton.

Understanding personal triggers is a vital aspect of managing eczema. It often involves a process of trial and error, and what works for one individual may not work for another. Regular consultations with a healthcare provider can also help tailor a prevention strategy that’s most effective for your specific type of eczema.

Effective Treatments

Eczema treatment aims to heal the affected skin and prevent flares. Since eczema varies from person to person, treatments must often be tailored to individual needs. Here are some general strategies:

Skin Care Regimens

  • Moisturising: Regularly applying moisturiser helps maintain skin hydration, which is crucial for eczema management. Thicker creams or ointments are often more effective than lotions.

  • Gentle Cleansing: Using mild, soap-free cleansers can help prevent skin irritation.

Medical Treatments

  • Topical Treatments: Steroid creams are applied directly to the skin to reduce inflammation and ease symptoms.

  • Phototherapy: Involves exposing the skin to controlled amounts of natural or artificial light. It’s beneficial for severe eczema or when other treatments are ineffective.

  • Systemic Medications: For severe cases, medications taken orally or injected can help regulate immune system responses and alleviate symptoms.

  • Wet Wraps: A technique involving applying medicated or moisturising creams to the skin followed by wet bandages to enhance the effectiveness of the treatment.

Lifestyle Changes and Home Remedies:

  • Stress Management: Techniques such as meditation, yoga, or counselling can help manage stress, a common trigger for eczema.

  • Dietary Changes: Some individuals find that certain foods exacerbate their symptoms and may benefit from dietary adjustments.

  • Avoiding Triggers: Identifying and avoiding personal eczema triggers can significantly reduce flare-ups.

Natural Remedies

  • Natural Oils: Certain oils, like coconut oil, have moisturising properties and can be beneficial for some people with eczema.

  • Mind-Body Practices: Acupuncture and other holistic therapies might provide relief for some individuals.

It’s essential to work with a healthcare provider to determine the most effective treatment plan, as what works for one person may not be as effective for another. Regular follow-ups and adjustments to the treatment plan are often necessary to manage eczema effectively over time.

Coping with Eczema

Coping with eczema extends beyond medical treatments, encompassing a holistic approach to managing both physical discomfort and emotional well-being. Living with eczema can be challenging, often requiring lifestyle adjustments and coping strategies. 

It’s important for individuals to educate themselves about their condition, identify and avoid personal triggers, and adhere to a regular skincare routine. Managing stress through relaxation techniques, support groups, or counselling can also play a crucial role in mitigating flare-ups. 

Staying connected with a supportive community, whether through online forums, local support groups, or with friends and family, can provide emotional support and practical advice. 

Additionally, keeping up with regular medical appointments ensures ongoing, personalised care. By combining these approaches, those affected by eczema can lead a more comfortable, fulfilling life despite the challenges posed by this chronic condition.

Seeking Professional Help

Seeking help from a healthcare professional is vital for managing eczema, particularly when self-care isn’t enough. If eczema symptoms persist, get worse, or affect your daily life and mental health, it’s important to see a doctor. 

Dermatologists, experts in skin conditions, can give a detailed diagnosis and create a treatment plan suited to you. They’ll also guide you on lifestyle changes and skincare to help control symptoms. If eczema leads to sleep problems, a lot of discomfort, or mental stress, you might need to see specialists like allergists, immunologists, or mental health experts. These professionals can deal with any allergies, immune system issues, or mental health factors linked to your eczema. Getting help early and regularly can control eczema better and prevent more serious problems, improving your quality of life.
