What is eczema?

Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by inflamed, itchy, and dry patches of skin¹. The condition often presents in cycles, with periods of flare-ups followed by remission. While the exact cause remains unclear, a combination of genetic and environmental factors plays a role in its development.

Eczema is not a contagious condition². Although there is no definitive cure, various treatments aim to alleviate symptoms and prevent flare-ups. Factors such as irritants, allergens, and stress can exacerbate the condition. Proper skin care and medical interventions can help manage its effects.

7 Types of Eczema

Eczema is more than just a singular skin condition; it’s a group of skin disorders that cause inflammation, itchiness, and redness. Below are the various types of eczema explained.

1. Atopic Dermatitis

The most common form of eczema is often linked with other allergic conditions such as asthma and hay fever. It presents as dry, itchy, and inflamed skin.

2. Contact Dermatitis

This type arises from direct contact with irritants or allergens, like chemicals or nickel, causing skin irritation or allergic reactions respectively.

3. Dyshidrotic Eczema

Characterized by small, itchy blisters on the edges of the fingers, toes, palms, and soles of the feet, which can be painful.

4. Neurodermatitis

Triggered by intense itching, affecting 12% of the population. The skin in affected areas often shows visible lines, scales, and discoloration from excessive itching. Common sites include the feet, ankles, hands, wrists, elbows, shoulders, neck, and scalp.

5. Nummular Eczema

Identifiable by round, coin-shaped spots on the skin, often appearing after a skin injury such as a burn or abrasion.

6. Seborrheic Dermatitis

Mainly affects the scalp leading to dandruff, but can also cause red, scaly patches on the face, especially around the nose and eyebrows.

7. Stasis Dermatitis

Associated with blood flow issues in the veins of the lower legs, leading to fluid buildup, itching, and reddish-brown discoloration of the skin.

Each type of eczema has unique symptoms and may require different types of treatment. It’s crucial to consult with a dermatologist for an accurate diagnosis and appropriate management plan.

Symptoms

Eczema is a skin condition known for its itching and inflammation. While it can affect individuals of all ages, the symptoms can manifest differently across age groups³. Here’s a breakdown:
