Stage 1 · First few days
Blisters
First itching or prickling, then tiny, tense blisters along the sides of the fingers and on the palm. They sit deep, so they feel like grains of rice. Some merge into a bigger one.

Dyshidrotic eczema: the blisters under your skin have 3 stages
First you feel itching, prickling or burning. Then you notice clear little blisters along the sides of your fingers or on your palm. If you squeeze or scratch them, “water” comes out. Two or three weeks later the blisters are gone, but your hand starts to peel, feel tight and crack.
These aren’t three different problems. They’re three stages of the same cycle. The blisters aren’t filled with trapped sweat, and the condition isn’t contagious. The stage you’re in decides what your skin needs most: calming the inflammation, protection from a trigger, or rich care for the skin barrier.

How we put this article together
This article is based on European hand eczema guidelines and peer-reviewed research. Every number links to its source, both in the text and in the list at the bottom of the page. The content is for education and doesn’t make a diagnosis. Chicatella publishes this article and sells the products shown near the end.
The key points in 30 seconds
Seven things worth remembering
01
The blisters are about 1–2 mm (under 1/10 in) across and look like they sit deep in the skin.
02
They show up on the palms, the sides of the fingers or the soles of the feet.
03
They itch a lot and can burn or hurt.
04
They’re not caused by blocked sweat glands, and they’re not contagious.
05
A single wave often lasts 2–3 weeks, then the skin peels.
06
The exact cause isn’t known, and triggers vary from person to person.
07
Flare-ups that keep coming back call for tracking down the triggers and, if needed, treatment from a dermatologist, not just switching creams.
What it looks like
3 stages people often mistake for 3 different problems
The same finger, three to four weeks apart. Blisters, peeling and cracks are one flare-up in three stages, not three conditions. Once you know that, you stop changing your routine every week and stop hunting for three different culprits. The sketches are simplified and aren’t a tool for diagnosing yourself.
Why the stages matter: care is different in each stage. During the blister stage your skin needs calm. During peeling and cracking it needs rich barrier care. Using the same cream the whole time isn’t a mistake. Switching products every week is.
FAQ
Quick answers first
What is dyshidrotic eczema?
A type of eczema with tiny, very itchy blisters on the palms, along the sides of the fingers or on the soles. It runs in a cycle: itching and blisters, then peeling, then dry, cracked skin. More in the section on the three stages.DermNet↗︎
Is dyshidrosis contagious?
No. It doesn’t spread through touch or a shared towel. It comes from an inflammatory reaction in the person’s own skin.
Is the fluid in the blisters sweat?
No. The name comes from an old theory about blocked sweat glands that research hasn’t confirmed. The fluid collects between skin cells because of inflammation. More in the section about the name.
How long does a single flare-up usually last?
A single wave often lasts about two to three weeks. Then the blisters dry out and the skin starts to peel, which can take a while longer.
Can I pop the blisters?
No. The unbroken top layer protects the skin underneath, and popping raises the chance of irritation and infection. If the flare-up is bad, talk to a doctor.
Does stress cause dyshidrosis?
Some people list stress among their triggers or things that make it worse, but it’s not a proven cause of the condition. We explain the difference between a cause and a trigger in this section.
What’s the difference between dyshidrotic eczema and a fungal infection?
Dyshidrotic eczema often shows up on both hands and runs in a cycle. A fungal infection is more often worse on one side and can come with changes on the feet. A test of skin scrapings for fungus is the reliable way to tell them apart. The comparison is here.

How to recognize and care for each stage
Tap a stage to see what’s happening in your skin, and what it actually needs at that point.
Stage
Stage 1 · itching and deep blisters
First prickling, itching or burning.
What it needs: calming the inflammation.
Cosmetic care makes sense only in the second and third stages.
The first “aha” moment
Why do the blisters seem trapped under the skin?
- →Inflammation makes the cells in the top layer of skin pull apart a little.
- →Fluid starts to collect between them. Doctors call this spongiosis.
- →On the palms and soles, the top layer of skin is especially thick.
- →That’s why the blisters are tense and look like they’re deep under the surface.Source↗︎
Picture tiny pockets of water forming between the tiles, not under them. This is just a simplified explanation, not an exact anatomical drawing.
Cross-section of palm skin
The name stuck, the explanation didn’t
The condition is named after sweat, but the blisters aren’t sweat
Not
blocked sweat gland → trapped sweat
Is
inflammation → skin cells pull apart → blister
- →The name comes from an old theory that faulty or blocked sweat glands cause the condition.
- →Research hasn’t confirmed that explanation.
- →Still, heavy sweating can make a flare-up worse for some people. So excess sweating can be a trigger, but it’s not what’s inside the blister, and it’s not a universal cause.
Three different ideas
A cause, a trigger and a look-alike aren’t the same thing
Mixing up these three ideas is exactly why so many conflicting explanations float around online.
Explanation
Cause
Tap one of the three ideas.
Related guides: contact dermatitis explains the difference between irritation and a delayed allergy, and atopic dermatitis covers a tendency toward sensitive skin.
A surprising check
The blisters are on your palm, but the trigger may be between your toes
A possible link, not a given
- →A fungal infection on the foot can cause fungal changes or a distant inflammatory reaction with blisters on the palms.
- →That kind of reaction isn’t necessarily a fungal infection of the palm itself.
- →A doctor can check your feet and, if needed, do a test of skin scrapings for fungus.
- →Changes on just one side are one more reason to get checked for fungus.
- →This doesn’t mean that all blisters on one hand are fungus.
Testing
An allergy test that isn’t the usual allergy test
Relevant for this condition
Patch test on the back
It looks for a delayed contact allergy, a reaction that only shows up after a day or two. Doctors call it patch testing.
A different purpose
Skin prick test
It’s used for a different type of allergic reaction that happens fast. So it’s not the right test for finding a contact allergy.
When a patch test makes extra sense
01
Long-lasting or recurring problems
Flare-ups that last for months or keep coming back for no clear reason.
02
Poor response to standard treatment
No lasting improvement despite consistent care and prescribed medication.
03
A clear link to work or a product
Worse after a work week, better on vacation, or after a new product.
04
An unusual pattern
Spots that don’t follow the usual palm-and-finger pattern.
05
Suspicion of specific substances
Metals, rubber additives, preservatives, fragrances or acrylates.
We don’t recommend nickel-free or cobalt-free diets for everyone with dyshidrosis. Cutting foods may only make sense for selected people with a proven contact allergy, under professional guidance.S2k↗︎
The paradox
Rubber gloves can save your hands, or turn into a sauna
The glove stops the detergent
The glove traps moisture and heat
A cotton glove as a middle layer
Before you put gloves on, your hands should be dry.
Wear gloves only as long as you need to.
If the inside gets damp, change them.
For longer wet work, it can help to use a dry fabric liner or cotton under-gloves.
The inside has to stay clean and dry.
We don’t give a one-size-fits-all recommendation on glove material here, because some people are allergic to ingredients in rubber. If it’s work-related, choose your protection with a dermatologist or an occupational safety expert.Part 2↗︎
Telling them apart
How do you tell similar rashes apart?
| Condition | What’s typical | Itchy or painful? | One side or both? | Key clue |
|---|---|---|---|---|
| Dyshidrotic eczema: the 3 stages of the blisters | Deep, tiny blisters, then peeling | Usually very itchy | Often both | A repeating cycle |
| Fungal infection | Peeling, often worse on one side | Itchy | Often one side | Changes on the feet too |
| Contact dermatitis | Where the contact happened or a bit wider | Itches or burns | Depends on the contact | A new product or exposure at work |
| Herpes rash on a finger | A cluster of painful blisters | More often painful | Usually one finger | Strong tenderness and pain |
| Pustular psoriasis | Deep sterile pustules, thickened skin | Can burn or hurt | Can be both | A different course and look |
| Scabies | Itching, often worse at night | Very itchy | Can be both | People close to you have it too |
This table isn’t a diagnostic test. The looks overlap, so if things are unclear or don’t go away, a checkup is worth more than comparing photos.
Treatment
Treatment should follow the stage, not just the name of the condition
While blisters are forming
- cold compresses can ease the itch for a while;
- there’s no point popping blisters at home;
- for a strong flare-up, doctors often use a topical anti-inflammatory medicine;
- skin on the palms is thick, so a doctor decides which medicine to use and how strong;
- we don’t swap prescribed medicine for cosmetics.
As the blisters dry out
- peeling begins;
- the new surface can be sensitive;
- hot water, frequent washing and rubbing make the discomfort worse;
- regular moisturizing and protective care becomes really important.
When skin cracks and it keeps coming back
- treatment has to include looking for irritants, allergens and possible fungus;
- hand eczema counts as chronic if it lasts more than three months or comes back at least twice in one year;Part 1↗︎
- a dermatologist may use phototherapy, treatment for sweating, or other topical or systemic medicines;
- treatment is tailored to the actual cause and to any overlapping types of hand eczema.EADV↗︎
Research
What has changed in hand eczema treatment?
The first new topical treatment developed specifically for chronic hand eczema
In September 2024, the European Medicines Agency approved delgocitinib for adults with moderate to severe chronic hand eczema when topical corticosteroids aren’t suitable or don’t work well enough.EMA↗︎
It’s a topical JAK enzyme inhibitor that turns down several inflammatory signals.
It’s a prescription medicine, and a doctor manages the treatment.
Two studies · 960 adults · 16 weeks

DELTA 3 followed 801 participants and supported keeping control for up to 52 weeks in total. The extension was open-label, so this is supporting long-term evidence, not as strong as the double-blind studies.DELTA 3↗︎
DELTA FORCE (2025) compared topical delgocitinib with oral alitretinoin in severe chronic hand eczema and found a bigger average improvement in the HECSI score with delgocitinib.DELTA FORCE↗︎
Two important notes
- The studies looked at chronic hand eczema with different subtypes, not only dyshidrotic eczema.
- The main studies were funded by the manufacturer, and the EMA assessed the data for approval.2026 review↗︎
This section isn’t a recommendation for any specific medicine. It’s here to show that stubborn hand eczema now has some new options from dermatology too.
In practice
What can you do at home?
After washing
- lukewarm water, not hot;
- pat dry gently and thoroughly, including between your fingers;
- care for dry skin again right away;
- no rubbing with a rough towel.
During wet work
- suitable protective gloves;
- dry hands before you put them on;
- wear them for as short a time as you can;
- change them if the inside gets damp;
- a cotton liner for longer wear, if it suits the job.
When it itches
- a cold compress;
- short nails;
- no popping or squeezing blisters;
- take a photo of a fresh flare-up for your appointment;
- prescribed treatment as your doctor tells you.
During calmer stretches
- keep up the protective care;
- keep track of flare-ups;
- cut down on wet work you don’t need to do;
- a diary of possible triggers;
- protection from cold and friction.
We advise against alcohol, essential oils, undiluted acids, DIY disinfecting and general elimination diets.
Next step
When should you get it checked?
the blisters show up for the first time and it’s not clear what they are
it affects only one hand or one foot
flare-ups disturb your sleep, walking or use of your hands
they come back at least twice a year
the problem lasts more than three months
treatment and avoiding irritants don’t help
there’s a clear link to your work
there are changes between your toes
the skin gets more and more painful or warm, or starts to ooze
A very painful cluster of blisters on one finger, quickly spreading redness, fever or feeling generally unwell need a doctor’s assessment fast.
Chicatella care
Once the blisters settle, a different problem starts, and this is where good care can really help
Active blisters come from inflammation. But after a flare-up, what’s left is a dry, sensitive, cracked skin barrier. That’s when skin loses water faster, and every contact with water or friction puts more strain on it.
Chicatella supports the care of dry skin whose surface has closed over. Active inflammation and recurring blisters need a proper diagnosis and treatment.
What stage are your hands in?
This isn’t the moment for a new product. It’s the moment for:
cooling
protection from a known trigger
prescribed anti-inflammatory treatment
a checkup if the flare-up is strong or unclear

To wrap up
Read your skin’s needs correctly
Deep blisters, peeling and cracks are different stages of the same cycle, so the same fix isn’t right at every moment. Active inflammation needs calming and, if needed, treatment. Flare-ups that keep coming back need you to find the trigger. And dry skin that has closed over after a flare-up needs consistent repair and protective care. The best routine starts with one question: “What does my skin need today?”
