Condition

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.

Eczema = sensitive skin.

Some types come and go, some stay for years.

Treatment comes down to moisturizing and protecting your skin even when it looks normal. Eczema-prone skin is never as strong as normal skin.

Key Facts

−
How commonOne of the most common skin conditions there is - roughly one in five children and a smaller share of adults
Who gets itUsually starts before the age of five. Most common in people who also have asthma, hay fever or food allergy, or a family history of them
Curable or managedManaged. Many children improve a lot by their teens, but the tendency to dry, easily irritated skin usually stays
Prescription neededOften. Mild eczema can be held with moisturizer and over-the-counter hydrocortisone; anything more usually needs a prescription
Time to improveA flare treated properly usually settles within one to two weeks

What It Is

−

Eczema is the everyday word for a group of conditions that leave skin dry, itchy and inflamed. Doctors call the group eczematous dermatitis. Atopic dermatitis is the most common kind and the one this page describes.

Two things go wrong at once. The outer layer of skin, meant to hold water in and keep irritants out, is leaky. And the skin's immune system overreacts, so ordinary things - soap, dust, sweat, a rough sweater - set off inflammation that would not bother anyone else.

The result is dry, itchy, often cracked skin that looks red or discolored. In a flare it weeps, crusts and swells. Skin scratched for years thickens and its fine lines deepen; that is lichenification.

Eczema takes several shapes and the tiles below let you pick yours. Atopic dermatitis is the long-term type that runs in families. Some get it mainly on the eyelids, some mainly on the hands. The same treatments work for most, with the gentlest kept for the eyelids.

Where it shows up depends on age. In babies, the cheeks, scalp and outer limbs. In older children and adults, the creases - inside the elbows, behind the knees, neck, wrists and ankles. Adults often get it on the hands, eyelids and around the mouth.

Eczema is not contagious, and it is not an allergy to one thing you can find and remove. It runs in families alongside asthma, hay fever and food allergy - the atopic conditions, which is where the name comes from.

Symptoms

−
Sensitive
Calm but easily set off

Sensitive

Skin between flares. It is not inflamed, but it is dry, tight, and quick to sting from soap, fragrance or a new product. This is the state eczema skin sits in most of the time, and the one where daily moisturizer does the most work.
Acute Flare
Red, weeping, very itchy

Acute Flare

Bright red, swollen skin that may weep, blister or crust, and itches enough to disturb sleep. It usually appears in the elbow and knee creases, the neck and the hands. In deeper skin tones the redness can read as purple, gray or simply darker than the surrounding skin.
Chronic + Thick
Leathery patches

Chronic + Thick

Skin that has been rubbed and scratched for months becomes thickened, leathery and marked with deeper lines. It often itches without looking dramatic. Breaking the scratch cycle matters as much as treating the rash.
Eyelid Dermatitis
Itchy, flaky, swollen

Eyelid Dermatitis

Eyelid skin is the thinnest on the body, so eczema here looks dry, flaky and puffy, with fine wrinkling and stinging rather than an obvious rash. It is often set off by something the hands carried up to the face - shampoo, nail polish, a cleanser or an eye cream. Only mild steroids or the non-steroid creams belong on eyelids, and only for short stretches.
Hand Dermatitis
Dry, cracked, sore

Hand Dermatitis

Dryness, cracking and painful splits across the fingers and palms, sometimes with deep, very itchy blisters along the sides of the fingers. Frequent handwashing, gloves and wet work keep it going, which is why it is common in healthcare, food and cleaning jobs. It is the version of eczema most likely to carry on into adult life.
Atopic Dermatitis
Runs in families

Atopic Dermatitis

The most common type, and the one most people mean by eczema. It usually starts in childhood, runs in families alongside asthma and hay fever, and sits in the elbow and knee creases, the neck, the wrists and the hands. It comes in flares on a background of dry, easily irritated skin.

How It Looks by Skin Tone

−
Extreme close-up of light skin in an active eczema flare, too close to tell which part of the body it is. Blotchy pink-red inflammation covers the whole frame with no clear edge, with small raised bumps, fine dry scale and a few fresh scratch marks.Extreme close-up of medium, olive-toned skin in an active eczema flare, too close to tell which part of the body it is.

Blotchy violet-brown inflammation covers the whole frame with no clear edge, and the raised bumps and dry scale show more clearly than the color change does.Extreme close-up of deep, dark brown skin in an active eczema flare, too close to tell which part of the body it is. Almost no redness is visible - the whole frame reads slightly darker and grayish, with raised bumps, dry scale and fresh scratch marks giving it away.
LightMediumBrownDeep

On deeper skin tones, eczema often does not look red. Inflamed skin looks violet, gray, dark brown, or just darker than the skin around it. That matters, because eczema here gets scored as mild when it is not, and undertreated. Feel the skin for warmth, thickening and roughness - more reliable than color.

It is also more likely to appear as small bumps around the hair openings, mistaken for goosebumps or tiny pimples, and to sit on the outer arms and legs rather than only in the creases, so the classic pattern may not be yours. What it leaves behind is usually the bigger complaint. Settled patches heal into flat marks darker than the surrounding skin, and sometimes into lighter patches where pigment dropped out. Both take months to even out, and the light ones take longer. Neither is a scar, and neither comes from the treatment. Pigment returns on its own once inflammation is fully controlled, so treating early shortens the wait. Long scratching also thickens skin more readily on deeper skin tones - one more reason to treat the itch instead of living with it.

Where It Shows Up

−
Front view of a whole body with red marks on the face and scalp, on the outer surfaces of both arms and on both legs. The nappy area is clear.
Baby
The baby and toddler pattern. It favors the cheeks and scalp first, then the outer surfaces of the arms and legs. The diaper area is usually spared, because it stays damp.
Front view of a whole body with red marks in the creases of both elbows, behind both knees, on both sides of the neck and on both wrists.
Child
The pattern from about age two onward, and the one most people picture. Skin folds trap heat and sweat, and they are the easiest places to reach and scratch.
Front view of a whole body with red marks on both hands and fingers and on the face and neck. The rest of the body is clear.
Adult
The adult pattern. Hands take the most washing, gloving and wet work, and the thin skin of the eyelids and lips reacts to whatever the hands carry up to the face.

What Happens in the Skin

This is what is going wrong under the skin, in the order it happens. Click a step to see it.

How Eczema happens
Skin basics
BARRIEREPIDERMISDERMIS0NORMAL SKIN1GAPS IN THE BARRIER2SKIN THAT IS EASILY IRRITATED3INFLAMMATION AND INCREASED BLOOD FLOW4BACTERIA GROW ON DAMAGED SKIN

In healthy skin the outer layer is a tight wall of flat cells held together by fats. It keeps water in and keeps irritants, allergens and bacteria out, and the living skin underneath stays calm.

In eczema that wall is built loosely and has gaps in it. Many people carry a change in filaggrin, one of the proteins the wall is made from. Water escapes through the gaps, so the skin is dry, and things from outside get in.

With the wall broken, soap, sweat, dust and rough fabric reach the living skin underneath. Things that would not bother anyone else set it off - and scratching pulls the gaps wider still, which is what makes the cycle repeat.

The immune system reacts to everything getting through. Blood vessels widen and immune signals pour out, which is what makes the skin swollen, warm and discolored. Those same signals act on nerve endings, which is why eczema itches before there is much to see.

Staphylococcus aureus sits harmlessly on most people's skin, but broken eczema skin lets it multiply. It drives the inflammation up again, which is why a flare can turn much worse over a day or two.

The outer film of dead cells and oil. It holds water in and keeps irritants out, and it is thinner than a sheet of paper. Almost every dry, itchy, stinging skin problem starts here.

The outer layer, and the only one anything in a jar reaches. It renews itself constantly: a cell made at the bottom takes about a month to reach the surface and flake off. Most of what a skincare product does, it does here.

The living layer underneath, holding the blood vessels, the nerves and the collagen. It is where lasting change happens and it is hard to reach: most of what is sold for the skin never gets this far.

Two systems are involved, and each makes the other worse.

First the skin barrier - the outer layer of skin, a wall of flat cells held together by fats. In eczema that wall is weak. Many people with eczema carry a change in a gene called filaggrin, which builds one of the wall's proteins. A weak wall lets water out, so skin is dry, and lets irritants, allergens and bacteria in, so the immune system keeps meeting things it would never otherwise see.

Second the immune system, tilted toward a particular kind of inflammation driven by signals called interleukin-4, interleukin-13 and interleukin-31. They cause the swelling and discoloration, and they act directly on nerve endings to cause itch. That is why eczema itches before there is much to see.

Then the loop closes. Itch leads to scratching, scratching breaks the barrier further, more inflammation follows. Scratched skin also loses its ability to hold off Staphylococcus aureus, a bacterium that sits harmlessly on most skin but grows heavily on eczema skin and drives inflammation up again.

None of this comes from poor hygiene, and there is no hidden allergy underneath it to find and remove.

Risk Factors

−

Eczema is mostly something you are born prone to. These make it more likely - nobody's fault.

Inherited
Family history
The strongest single factor. Eczema, asthma, hay fever and food allergy cluster in families, so a parent with any of them raises your chance.
Inherited
Filaggrin gene changes
A common inherited change in a protein that builds the skin barrier. It makes eczema more likely, earlier and longer-lasting.
Inherited
Other atopic conditions
Asthma, hay fever and food allergy often travel with eczema, in any order.
Inherited
Skin that has always been dry
Often the mildest version of the same tendency.
Age
Age
Most eczema starts in the first five years of life, often the first year. Adult-onset happens but is less common.
Environment & work
Dry, cold climates
Low humidity and long winters with indoor heating mean worse flares.
Environment & work
Urban living and hard water
Both linked to higher rates. The link is modest and nobody knows why.
Environment & work
Wet work
Nurses, hairdressers, cleaners, cooks and mechanics wash and glove their hands dozens of times a day, which is why hand eczema is common.

Course

−

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.

First year0-12 months
Often the first appearance

Red, weepy, intensely itchy patches. Babies rub rather than scratch, so broken sleep is often what parents notice first.

CheeksScalpKneesElbows
Under fiveToddler years
Most cases have started by now

The rash leaves the face for the skin folds. Patches turn drier and scalier, and scratching becomes deliberate.

Elbow creasesBehind the kneesWristsAnkles
School ageRoughly 5-12
A large share of children improve substantially

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.

Teens13-19
More improve again

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.

HandsEyelidsNeck
Adult20 and up
It rarely disappears completely

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.

What helps

  • Moisturize generously, every day An artificial barrier.
  • Ceramides, glycerin or petrolatum The best-supported ingredients.
  • Short, lukewarm showers Gentle cleanser, pat dry, moisturizer straight after.
  • A humidifier in winter If your eczema is seasonal.
  • Short nails and gloves at night Limits scratching in your sleep.

What makes it worse

  • Scratching Tears the gaps wider.
  • Stopping moisturizer The top reason a flare returns.
  • Long, hot showers Strip the fats holding the barrier.
  • Soap and foaming cleansers Heavy foam strips barrier fats.
  • Frequent handwashing The main driver of hand eczema.
  • Dry indoor air in winter Heating drops indoor humidity.

What helps

  • Cool the skin Cool compresses and a cooler bedroom quiet it.
  • Cotton and loose clothing Less triggering all day.

What makes it worse

  • Fragrance A top irritant.
  • Sweat and overheating A very reliable itch trigger.
  • Wool and rough fabrics Set the itch off directly.

What helps

  • A topical steroid for flares Mild on the face, stronger on the body.
  • Non-steroid prescription creams Calm inflammation without thinning skin.
  • Proactive treatment Twice a week on flare-prone spots lengthens the gaps.
  • Treat early A flare caught early takes far less treatment.
  • A sedating antihistamine at night Helps you sleep through the itch.
  • Injected and oral treatments For severe eczema, under a specialist.

What makes it worse

  • Night time Body heat rises, itch gets louder.
  • Stress and poor sleep Raise existing inflammation.
  • Dust mites, pollen, pet dander Matter if you have hay fever or asthma.
  • Stopping treatment early Undertreated flares return faster.

What helps

  • Treat infection Weeping or honey-colored crusts need an antibiotic.
  • Hypochlorous acid spray Lowers skin bacteria, does not sting.
  • Diluted bleach baths Only if your doctor recommends it.

What makes it worse

  • Weeping or yellow crusts Usually staph.

Sits on the surface and slows water escaping. It adds nothing to the skin; it stops what is there from leaving.

These are the materials the outer layer is built from. They fill the gaps rather than covering them.

The redness, swelling and itch are the immune system reacting, not the damage itself.

Over-the-Counter Products

−

Everything here you can buy without seeing anyone.

A white squeeze tube labeled Hydrocortisone lying on a plain white background16:9 hero for Hydrocortisone. Never cropped: the tone strip and the corner logo depend on the full frame.
Strong evidence
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.
Four petrolatum ointments on white: CeraVe, a Vaseline jar, a petroleum jelly tube and Aquaphor16:9 hero for Petrolatum. Never cropped: the tone strip and the corner logo depend on the full frame.
Strong evidence
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.
Four ceramide moisturizers lined up on white: two tubes, a CeraVe tub and a blue jar16:9 hero for Ceramides. Never cropped: the tone strip and the corner logo depend on the full frame.
Strong evidence
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.
Five colloidal oatmeal eczema products lined up on white, including Aveeno, Gold Bond and Eucerin16:9 hero for Colloidal Oatmeal. Never cropped: the tone strip and the corner logo depend on the full frame.
Moderate evidence
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.
Five white tubs of 40% urea cream lined up on white, two with cream visible inside16:9 hero for Urea. Never cropped: the tone strip and the corner logo depend on the full frame.
Moderate evidence
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.
Hypochlorous acid spray
Hypochlorous acid spray
Limited evidence
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.
A sedating antihistamine at night
A sedating antihistamine at night
Limited evidence
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.

Prescriptions

−

The basics stay put - a gentle cleanser, a moisturizer and a daily sunscreen are right whichever kind you have.

These need a prescription.

A white tube labeled Triamcinolone with a blue swoosh, lying on a plain white backgroundDiagram: how Triamcinolone Acetonide works in the skin
Strong evidence
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.
A white ointment tube labeled Tacrolimus with a blue swoosh, lying on a plain white backgroundDiagram: how Tacrolimus (Protopic) works in the skin
Strong evidence
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.
A white cream tube labeled Opzelura with a blue swoosh, lying on a plain white backgroundDiagram: how Ruxolitinib Cream (Opzelura) works in the skin
Strong evidence
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.
A white metal tube labeled Clobetasol with a teal swoosh, lying on a plain backgroundDiagram: how Clobetasol works in the skin
Strong evidence
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.
16:9 hero for Tapinarof. Never cropped: the tone strip and the corner logo depend on the full frame.Diagram: how Tapinarof works in the skin
Strong evidence
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.
16:9 hero for Roflumilast Cream (Zoryve). Never cropped: the tone strip and the corner logo depend on the full frame.Diagram: how Roflumilast Cream (Zoryve) works in the skin
Strong evidence
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.
A white metal tube labeled Desonide with a blue swoosh, lying on a plain backgroundDiagram: how Desonide works in the skin
Moderate evidence
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.
A white tube labeled Eucrisa with a teal swoosh, lying on a plain backgroundDiagram: how Crisaborole (Eucrisa) works in the skin
Moderate evidence
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.
A white metal tube labeled Pimecrolimus with a teal swoosh, lying on a plain backgroundDiagram: how Pimecrolimus (Elidel) works in the skin
Moderate evidence
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.
An amber pill bottle labeled Cyclosporine on its side with round white tablets spilling out16:9 hero for Cyclosporine. Never cropped: the tone strip and the corner logo depend on the full frame.
Strong evidence
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.
An amber prescription bottle lying on its side on a white background with a plain white label reading JAK Inhibitors, and six small round white tablets spilled out in front of it.
Oral JAK inhibitors
Strong evidence
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.
An amber pill bottle labeled Methotrexate on its side with round white tablets spilling outDiagram: how Methotrexate works in the skin
Moderate evidence
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.
An amber prescription bottle lying on its side on a white background with a plain white label reading Antibiotics, and six small round white tablets spilled out in front of it.
Antibiotics for infected eczema
Moderate evidence
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.
An amber pill bottle labeled Prednisone on its side with round white tablets spilling outDiagram: how Prednisone works in the skin
Limited evidence
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.
A white and green pre-filled injection pen labeled Dupixent lying on a plain background16:9 hero for Dupilumab (Dupixent). Never cropped: the tone strip and the corner logo depend on the full frame.
Strong evidence
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.
A white injector pen on a white background, with a plain white label reading Adbry and a blue swoosh beneath it.
Adbry
Strong evidence
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.

Procedures

−

These are done in the office, usually over several visits.

Strong evidence
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.

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.

When to See a Dermatologist

−

Book if two weeks of hydrocortisone and daily moisturizer have not settled it, if the itch wakes you or your child, or if the skin is painful or weeping. There is no test for eczema - I diagnose it by pattern and history, so you do not need photos to be taken seriously. A difficult rash occasionally needs a biopsy. The visit buys you a prescription-strength option once drugstore treatment has had a fair trial.

Complications

−

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.

Lookalikes

−

Psoriasis

Thicker patches with sharp edges and silvery scale, usually on the outside of the elbows and knees rather than inside the creases. It itches less than eczema and rarely weeps. On the scalp and the nails the two can look almost identical.

Ringworm

One round patch with a raised, scaly edge and a clearer center, spreading slowly outward. It is a fungus, so steroid cream calms it briefly and then makes it spread. A scraping sorts it out in minutes.

Scabies

Fierce itch that is worst at night, with tiny burrows in the finger webs, the wrists and around the waist. The giveaway is that other people in the house start itching too. Eczema creams will not touch it.

Myths

+
  • “Eczema is caused by poor hygiene.” It is an inherited difference in the skin barrier and the immune system. Washing more does not help; harsh soap makes it worse.
  • “Eczema is contagious.” It is not You cannot catch it or pass it on by touch, in a pool, or by sharing a towel.
  • “It is an allergy - we just need to find the food.” For most people there is no single trigger. Food allergy and eczema often occur together, especially in young children, but cutting foods out rarely clears eczema and carries its own risks. Test only for a clear, repeatable reaction to a specific food.
  • “Topical steroids are dangerous and should be avoided.” Strong steroids on thin skin for long stretches thin it, which is why strength is matched to body area and courses are limited. Used as prescribed they work and do no harm. An undertreated flare does more damage over months than proper treatment does in two weeks.
  • “Moisturizer is just for comfort.” Over a year it does the most work of any treatment. It cuts flares and prescription cream use.
  • “Children always grow out of it.” Many improve a great deal and some clear completely. But the dry, easily irritated skin usually stays, and eczema can come back in adulthood, often on the hands.
  • “Natural products are gentler.” Plant and essential oils are a common cause of allergic reactions in eczema, and some make the barrier worse. Fragrance-free matters more than natural.

Questions Patients Ask

+

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.
