Eczema & Dermatitis
Eczema (atopic dermatitis) causes dry, itchy, inflamed skin. Here's what it is, what can trigger it, and when it's worth having assessed.
Causes dry, itchy, inflamed skin in flare-ups
Not contagious — a skin barrier condition
Usually well managed with the right plan
Knowing your triggers helps a lot
Eczema, also called atopic dermatitis, is a common condition that makes the skin dry, itchy, and inflamed. It often comes and goes in flare-ups, and while there's no single cure, it can usually be managed well so it interferes less with daily life and sleep.
What it looks and feels like
Eczema typically causes dry, itchy patches that may look red or discoloured, feel rough, or become cracked. It commonly appears on the hands, the insides of the elbows, behind the knees, and on the face and neck — though it can occur anywhere. Scratching tends to worsen it, which is why easing the itch matters.

Flare-ups can be set off by dryness, soaps and detergents, certain fabrics, heat or sweating, stress, and allergens. Identifying your personal triggers is a useful part of managing it. A consistent gentle skincare routine and good moisturising are foundations most people benefit from.
When to seek care
It's worth being assessed if the itch is affecting sleep or daily life, if the skin looks infected (increasing redness, warmth, weeping, or crusting), or if it isn't settling with basic care. Your iCollab family doctor or a walk-in physician can assess it and coordinate dermatology input where appropriate.

A closer look
As you scroll, each part highlights on the diagram. This is general education, not a diagnosis.
Skin barrier
Eczema-prone skin has a weakened outer barrier, so it loses moisture and lets irritants in more easily — which is why dryness and flare-ups happen.
Surface
Affected skin can become dry, red, itchy, and rough at the surface. Gentle, consistent moisturising supports the barrier here.
Inflammation
The redness and itch come from an overactive immune response in the skin. Calming that inflammation is central to settling a flare.
Deeper layers
Scratching can disturb deeper layers and worsen the cycle. Breaking the itch-scratch loop is a key part of management.
