Eczema
Eczema is a group of long-term conditions in which the skin barrier leaks moisture and the immune system in the skin overreacts. Atopic dermatitis is the most common kind. The result is skin that is dry, itchy and inflamed, in flares that come and go. It is controlled rather than cured, and most of it responds well to treatment used properly.

Top things to know about Eczema
- It is a recurring inflammatory condition. Atopic eczema involves a vulnerable barrier and an itch–scratch cycle.
- Several factors reinforce each other. Dryness, irritants, inflammation and scratching feed one another.
- It is not about cleanliness. Vigorous cleansing can make eczema worse.
- Care has two parts. Emollients protect the barrier, while anti-inflammatory treatment settles active flares.
What it looks like
What Eczema looks like
Eczema, also called atopic dermatitis, causes dry, itchy, inflamed patches of skin. The itch is often the first and worst symptom, and scratching makes the rash worse. In babies, it often appears on the cheeks and outer arms and legs. In older children and adults, it favors the inner elbows, backs of the knees, neck, hands and eyelids. Long-term scratching can thicken the skin, making its lines more visible.
Eczema is a family of related conditions. Atopic dermatitis is the most common, but other types look and behave differently.
Atopic dermatitis
Long-term, starts in childhood.
Infant facial eczema
Inflamed, rough patches affect the cheeks.
Hand eczema
Dry, cracked or blistered hands.
Dyshidrotic eczema
Tiny itchy blisters on fingers and palms.
Nummular eczema
Coin-shaped patches.
Contact dermatitis
Triggered by something touching the skin.
Where it shows up
Adult: Skin creases, hands and neck
Eczema often affects the inner elbows and backs of the knees. In adults, the hands, face and neck may also be involved.
Child: Elbow and knee creases
In walking and school-age children, eczema often moves into the inner elbows and backs of the knees. The neck and wrists can also be involved.
Baby: Cheeks and outer limbs
Infant eczema often affects the cheeks and outer arms and legs. The diaper-covered area is usually spared.
Eyelids and neck
The thin skin around the eyes and the neck can be affected. These are example sites; adult eczema does not have one fixed facial pattern.
On different skin tones
Eczema on different skin tones
On lighter skin, eczema looks pink or red. On brown and Black skin, it is often dark brown, purple or ashen gray, and redness can be hard to see. Darker skin also more often shows small bumps around hair follicles and thickened skin. After flares, light or dark patches can remain for months.
What happens in Eczema?
In atopic dermatitis, a less effective skin barrier and overactive immune signals reinforce each other. Water escapes more easily, and itching and scratching can add damage and prolong inflammation.
- The barrier holds less moisture: Water escapes more easily through the outer skin.
- Itching fuels the cycle: Scratching adds damage and can worsen inflammation.
- Immune signals inflame the skin: Inflammation can further weaken the barrier.
Causes and triggers
What causes Eczema
Causes
Why it happens
Eczema comes from a weak skin barrier combined with an overactive immune response. Moisture escapes, irritants get in and the skin becomes itchy and inflamed.
Changes in the filaggrin gene, which helps build the skin barrier, are a major risk. Eczema often runs in families with asthma and hay fever.
Risk factors

When it usually starts
When it usually starts
Eczema
Often starts in infancy or childhood, though it can first develop in adulthood.
Daily care
Daily care for Eczema
Moisturize generously, every day
An artificial barrier.
Short, lukewarm showers
Gentle cleanser, pat dry, moisturizer straight after.
A humidifier in winter
If your eczema is seasonal.
Cool the skin
Cool compresses and a cooler bedroom quiet it.
Short nails and gloves at night
Limits scratching in your sleep.
Cotton and loose clothing
Less triggering all day.
Use a clinician-agreed maintenance plan on recurrent eczema sites
Twice a week on flare-prone spots lengthens the gaps.
Treat early
A flare caught early takes far less treatment.
Injected and oral treatments
For severe eczema, under a specialist.
Seek assessment for signs of skin infection
New pain, spreading redness, fever or crusting may need assessment. Not every weeping eczema flare needs antibiotics.
Hypochlorous acid spray
Lowers skin bacteria, does not sting.
Diluted bleach baths
Only if your doctor recommends it.
Plan for nighttime itch
Body heat rises, itch gets louder.
Seek assessment for new weeping, yellow crusts or worsening soreness
These can signal infection but also occur with inflammation. Ask for assessment rather than automatically starting an antibiotic.
Avoid: Scratching
Tears the gaps wider.
Avoid: Long, hot showers
Strip the fats holding the barrier.
Avoid: Soap and foaming cleansers
Heavy foam strips barrier fats.
Avoid: Frequent handwashing
The main driver of hand eczema.
Avoid: Dry indoor air in winter
Heating drops indoor humidity.
Avoid: Fragrance
A top irritant.
Avoid: Sweat and overheating
A very reliable itch trigger.
Avoid: Wool and rough fabrics
Set the itch off directly.
Avoid: Stress and poor sleep
Raise existing inflammation.
Avoid: Dust mites, pollen, pet dander
Matter if you have hay fever or asthma.
Avoid: Stopping moisturizer
The top reason a flare returns.
Avoid: Stopping treatment early
Undertreated flares return faster.
Treatments
Treatments for Eczema
Hydrocortisone 1%
The one steroid you can buy without a prescription, and the only step in this routine that treats rather than protects. A thin layer twice a day on the itchy patches, for up to two weeks at a time. Mild enough for the face and the eyelids for a few days, and too mild for skin that has gone thick and leathery.
Hypochlorous acid spray
A spray that lowers the amount of staph sitting on eczema skin, aimed at step four rather than at the inflammation itself. It does not sting, which makes it easier on children than a bleach bath. It is a helper for skin that keeps getting infected, not a treatment for the flare.
Sedating antihistamines
Taken at bedtime it helps you sleep through the itch, which is the honest reason to use it. It does not treat the itch of eczema — that comes from immune signals rather than histamine — so a non-drowsy antihistamine in the daytime does very little. Ask your doctor before using one in a young child.
Petrolatum
Plain ointment, over damp skin, as the moisturizer rather than beside it. It seals water in rather than adding any. It is the one thing that is safe to put on eyelids as often as you like, and on a weeping flare it is usually the best thing on the shelf.
Colloidal Oatmeal
An old remedy that holds up. It calms itch and helps the barrier, in a cream or in a lukewarm bath. It will not clear a flare, and it is a sensible everyday moisturizer for skin that is calm but easily set off.
Urea
A moisturizer with urea in it, for patches that have gone thick and leathery from years of scratching. 10% and above. It stings on raw or weeping skin, so it belongs to the dry, cracked stage rather than the sore one.
Ceramides
The fats that hold the outer wall of the skin together, and the ones eczema skin is short of. A ceramide cream used daily reduces how often flares happen and how much prescription cream you end up needing over a year. It will not clear an active flare on its own — it is the maintenance step, used on calm skin as much as on sore skin.
Triamcinolone Acetonide
Triamcinolone. A mid-strength steroid ointment, twice a day for one to two weeks. It is the usual next step when hydrocortisone is not enough. Not for the face, the eyelids or the armpits - the skin there is thin already.
Protopic
Protopic. An ointment that calms the same immune signal a steroid does, without being one. It does not thin skin, so it suits the eyelids, the face and the folds, and it can be used twice a week to stop flares coming back. Expect stinging for the first week or so.
Desonide
A low-strength steroid made for thin skin - the face, the eyelids, the folds, and young children. Twice a day for a week or two.
Eucrisa
Eucrisa. A steroid-free ointment for mild to moderate eczema, approved down to three months old. It burns on application for some people, which is the main reason it gets abandoned.
Elidel
Elidel. The gentler cousin of tacrolimus, in a cream rather than an ointment. Suited to mild eczema on the face and the eyelids. It stings less, and it does less.
Opzelura
Opzelura. A newer steroid-free cream that takes the itch down quickly. It is meant for short courses on a limited area of the body, and it carries the warnings that come with the JAK class.
Clobetasol
One of the strongest steroids there is, kept for thick, stubborn patches and for palms and soles. Two weeks at a time, then a break. Long stretches thin the skin.
Vtama
A steroid-free cream applied once a day, approved for eczema down to two years old. It calms the inflammation without thinning skin, and in trials the improvement often held for a while after stopping. Folliculitis — small spots around the hair openings — and headache are the side effects that come up, and it is newer and more expensive than a steroid.
Zoryve
Zoryve. Another steroid-free once-daily cream, approved for eczema down to six years old. It is well tolerated on the face and the folds, and it does not sting the way tacrolimus does in the first week. Like the other newer creams, the barrier is cost and coverage rather than whether it works.
Oral JAK inhibitors
Tablets for severe eczema that has not answered creams — they work fast, often taking the itch down within days. They need blood tests, and the class carries warnings about infection, blood clots and heart problems, so they are prescribed with a proper discussion of who they suit. Usually considered alongside the injections rather than before them.
Cyclosporine
Works fast on a severe flare, which is what it is for - weeks to months, not years. It raises blood pressure and strains the kidneys, so both are checked while you are taking it.
Methotrexate
A weekly tablet for long-running eczema. Cheaper than the injections and slower to work, with blood tests every few months. Ask your doctor about it before trying to conceive, and if you are pregnant or breastfeeding.
Prednisone
Oral steroids clear eczema quickly and it usually returns worse within weeks of stopping. Most dermatologists avoid them for that reason, and use them only to break a severe flare while something slower is started.
Antibiotics
A short course when a flare is weeping or carrying golden-yellow crusts, which usually means staph has taken hold. It clears the infection so the eczema treatment can work again. It is not a treatment for eczema itself, and taking it for every flare is how resistance builds, so it is used when there is something to treat.
Dupixent
Dupixent. An injection every two weeks, for eczema that covers a lot of skin and has not answered creams. It is not a steroid and it needs no blood monitoring. Eye irritation is the side effect people actually get.
Adbry
An injection every two weeks for moderate to severe eczema, blocking one of the same immune signals Dupixent does. It is the usual next thing to try when Dupixent has not worked well enough or has not been tolerated. No blood monitoring, and eye irritation is the side effect to know about, as with Dupixent.
Phototherapy
Measured doses of ultraviolet light in a booth, two or three times a week for a couple of months. It works. The cost is time, because it means getting to the office that often.
Excimer Laser
The same idea as the light booth, aimed at one patch instead of the whole body. Useful when a few stubborn areas are all that is left.
Outlook
What to expect with Eczema
Eczema comes in flares - calm skin, then days or weeks of itching and inflammation, then calm. Most people eventually name their own pattern: the season, the stress, the job, the week before a period. Underneath that, it follows a longer arc.
- 1
First year · 0-12 months
Red, weepy, intensely itchy patches. Babies rub rather than scratch, so broken sleep is often what parents notice first.
- 2
Under five · Toddler years
The rash leaves the face for the skin folds. Patches turn drier and scalier, and scratching becomes deliberate.
- 3
School age · Roughly 5-12
Flares get shorter and further apart. Skin between them is still dry and still needs daily moisturizer. Treating flares early and moisturizing daily between them change this stretch most.
- 4
Teens · 13-19
For those it stays with, it shifts to the areas that get the most use and washing. Patches scratched for years are thickened and darker by now, and that improves slowly once the itch is controlled.
- 5
Adult · 20 and up
The tendency stays, but flares are further apart. In adults the pattern is more chronic than episodic - low-level inflammation that never fully leaves, with flares on top. Hand eczema is the common adult version, and it tracks what the hands meet at work.
Complications
Complications to know about
Impetigo
Bacteria getting into skin that scratching has broken open. It shows as weeping and golden-yellow crusts sitting on top of an eczema patch, and it can turn a settled flare much worse in a day or two. It needs an antibiotic alongside the usual eczema treatment - more moisturizer will not clear it.
Sleep loss, fatigue and low mood
Itch is at its worst at night, so eczema costs sleep - for the person who has it, and often for the rest of the house. Months of broken sleep bring daytime fatigue and poor concentration, and anxiety and depression are more common in people with moderate or severe eczema. It is worth telling your doctor. Treating the eczema properly is usually what fixes the sleep.
Thickened, leathery skin
Months of rubbing and scratching the same patch thicken it into leathery skin with the normal lines cut deeper. Doctors call it lichenification. It itches on its own, and it takes far longer to settle than a fresh flare - stopping the scratching is the only thing that reverses it.
Dark or light marks after a flare
Settled patches often leave flat marks that are darker than the skin around them, and sometimes lighter patches where pigment has dropped out. Neither is a scar, and neither is caused by the treatment. They fade on their own, but over months rather than weeks, and they are more noticeable and longer-lasting on deeper skin tones.
New allergies to products
Broken skin meets far more of whatever is put on it, so people with eczema pick up contact allergies more easily - to preservatives, fragrance, and sometimes to the eczema creams themselves. Suspect it when a treatment that used to work starts to sting or spread the rash. Patch testing is how it is confirmed.
Eye problems
Eyelid eczema and constant rubbing lead to itchy, swollen lids and red, irritated eyes. In severe, long-standing eczema, a change in the shape of the cornea called keratoconus and early cataracts are uncommon but recognized. If the eyes are involved often, it is worth an eye check.
Hand eczema that gets in the way of work
Cracked, sore hands are hard to hide and hard to rest. In wet work - healthcare, food, cleaning, hairdressing, childcare - it can mean time off or a change of job. Treating it early and protecting the hands through the working day is what keeps it from getting that far.
The atopic march in children
Children with eczema are more likely than other children to go on to develop asthma, hay fever and food allergy, often in that order. Doctors call the pattern the atopic march. It is a tendency, not a certainty - most children with eczema do not get all of it.
When to get help
When to get help
When to seek care
Seek help for sleep-disrupting itch, recurrent flares or infection. Rapidly worsening painful skin with clustered blisters, fever or eye involvement needs urgent care.
Lookalikes
What else could it be?
Psoriasis
Psoriasis usually has thicker scale and clearer edges than eczema. Its patches often sit outside the elbows and knees, while eczema favors the inner creases.
Ringworm
Ringworm often forms a spreading ring with a scaly rim and clearer center. Eczema usually lacks that advancing edge; a skin scraping can help distinguish them.
Scabies
Scabies often itches most at night and may make other household members itchy. Eczema usually returns to familiar patches and does not spread between people.
Questions
Questions you might be asking.
Will my child grow out of eczema?
Many children improve a great deal by school age, and more through the teenage years. Complete, permanent clearance happens but is not the rule. What usually remains is dry, easily irritated skin that can flare again later, often on the hands. Treating it well in childhood does not guarantee it goes, but it means fewer flares, less scratching, less thickened skin.
Are topical steroids safe for my child?
Used as prescribed, yes. The rules are simple - mild strengths on the face, eyelids and skin folds, stronger ones for the body and limbs, and courses that run the length of a flare rather than indefinitely. Thinned skin and stretch marks come from strong steroids on thin skin for months without review. If you are using one more or less continuously, go back and ask about a non-steroid option.
Is a food causing this?
Usually not, and this is a common wrong turn. Food allergy is more common in children with eczema, but because both come from the same atopic tendency, not because food drives the rash. Removing foods rarely clears eczema, and long elimination diets can cause nutritional problems and even make a true allergy more likely. A clear, repeatable reaction within a couple of hours is worth investigating. A vague suspicion is not.
Why is it so much worse at night?
Several things line up after dark. Body temperature rises in the evening, and heat triggers itch directly. The distractions that kept you from noticing it are gone. Cortisol, which damps inflammation, is at its lowest overnight. And scratching in your sleep is unconscious, so damage piles up unchecked. A cooler bedroom, moisturizer right before bed, short nails and cotton layers help more than they sound.
Can I use the same cream on my face?
Not always. Facial skin, eyelid skin especially, is much thinner and absorbs more of what you put on it. A steroid strong enough for your shins can thin the skin around your eyes within weeks. Face and eyelid eczema is treated with a mild steroid for a short stretch, or a non-steroid cream that can be used long term. Ask before moving a body prescription to your face.
Do I still need moisturizer when the skin looks normal?
Yes. This is the single habit that separates people who flare four times a year from people who flare monthly. Skin that looks normal in eczema is still leaky - the barrier defect is there whether or not there is a rash. Daily moisturizer on calm skin keeps the next flare further off and smaller. It is maintenance, not first aid.
