What Is Eczema & How Do You Treat It?
Eczema—also called atopic dermatitis—is a chronic (long-lasting) inflammatory skin condition that makes the skin dry, itchy, red, and irritated. It tends to flare up and calm down in cycles, rather than being constant.
What’s happening in the skin
With eczema, the skin barrier doesn’t work properly. That means:
- Moisture escapes more easily → dry skin
- Irritants, allergens, and bacteria get in more easily → inflammation and itching
Common symptoms
- Intense itching (often the worst part)
- Dry, rough, or scaly patches
- Red, inflamed skin
- Cracking, oozing, or crusting in more severe cases
- Skin can become thickened over time from scratching
Where it usually appears
- Babies: cheeks, scalp, arms, legs
- Children: elbows, knees, wrists, ankles
- Adults: hands, eyelids, neck, inner elbows, behind knees
What causes eczema?
There’s no single cause. It’s usually a mix of:
- Genetics (often runs in families)
- Immune system overreaction
- Environmental triggers, such as:
- Soaps and detergents
- Fragrances
- Dry or cold weather
- Stress
- Allergens (dust mites, pollen, pet dander)
Eczema is not contagious.
Who gets it?
- Very common in children, but adults can have it too
- Many people with eczema also have asthma or allergies (the “atopic triad”)
How it’s managed (not cured)
There’s no cure, but symptoms can be controlled with:
- Regular moisturizing (especially thick balms or ointments)
- Gentle, fragrance-free skincare
- Avoiding known triggers
- Topical treatments prescribed by a doctor during flares
