What is Eczema? | Types of Eczema
Eczema is a group of skin conditions characterized by inflammation, redness, and itching. The most common types include:

Small, itchy blisters on hands and feet.

Scaly, flaky skin, often on the scalp (dandruff or cradle cap in babies).
6. Neurodermatitis
Thick, leathery skin patches due to excessive scratching.
Causes of Eczema | Why Does Eczema Occur?
The exact cause of eczema is unknown, but several factors contribute:
1. Genetics
A family history of eczema, asthma, or allergies increases risk.

Irritants (soaps, detergents, synthetic fabrics)
Weather (cold, dry air or excessive sweating)
4. Stress and Hormones
Emotional stress and hormonal changes can worsen symptoms.

A weak skin barrier allows moisture loss and bacteria penetration.
