Pompholyx eczema – The complete guide
Pompholyx eczema is also known as dyshidrotic eczema. It is a type of eczema that affects the hands and feet. In most cases, it can develop into itchy, watery blisters, mostly affecting the sides of the fingers, palms of the hands, and the soles of the feet. Some people also have a combination of pompholyx eczema and other types of eczema on their hands and feet.
It is more common in women.

What causes pompholyx eczema?
The exact causes of pompholyx eczema are not known, but it is thought that factors such as sensitivity to metal (compounds such as nickel, cobalt, or chromate), stress, heating, and sweating can aggravate this condition. For these reasons, pompholyx eczema can be difficult to manage and it can also cause problems with work.
Pompholyx eczema can also come with fungal infections, so the hands and feet should be checked for any infections.
The hands and feet are the areas where pompholyx commonly occurs, these areas are also prone to dermatitis (this can be in two forms – irritant contact dermatitis or allergic contact dermatitis).
It could also be caused by contact with detergents such as soap, detergents, solvents, acids, chemicals, and soil resulting in irritant contact dermatitis. Or, there could be an allergic reaction to a substance that is not commonly an irritant (such as nickel, cobalt, and chromium), resulting in allergic contact dermatitis.
List of triggers:
- Universal triggers for everyone:
- Exposure to water (like hot water, frequent hand washing, jobs like dishwasher and lifeguard)
- Stress
- Heat and sweat (living in high-humidity places)
- Harsh products (like soaps, shampoos, sanitizers with drying alcohols, detergents, and dishwashing soap). You can replace these products with hypoallergenic, unscented products.
- Common Allergies:
- Nickel is a common metal that people with eczema are allergic to (found in jewelry like rings, keys, and many foods like oatmeal and nuts). Other metals include cobalt and chromium.
- Food-related allergies or sensitivities (alcohol, sugar, dairy, spicy, gluten, meat, nuts) D
- Dust, mold, house dust mites, latex, and rubber (found in gloves) are some other triggers. 30-50% of people who have a latex allergy are allergic to certain foods like chestnuts, kiwis, bananas, avocados, passion fruits, and tomatoes.
- Uncommon triggers:
- Hard water (soft water is better for eczema, get a hard water filter or a water softener)
- Bodily changes (pregnancy, surgery, hormonal pills, etc)
- Parasites (ticks, mites, and especially intestinal parasites like worms are linked to eczema)
- Exposure to sunlight
- Other possible causes could be heat or a UV-related allergy but are very rare.
- Vitamin/mineral deficiencies (take a blood test to find out).
- Environment:
- Weather (hot summers or season shifts)
- Seasonal allergies (pet hair/dander)
- Dust, mold, or house dust mites (clean your house often and check for dust and mold in corners. Air purifiers can help with the mold in the air.)
- Dirty money, coins, fragrances, allergies to methylisothiazolinone/methylchloroisothiazolinone (MCI /MI), other chemicals in the isothiazolinones class, propylene glycol, and gel polish (Other options include a regular polish, press-on nails with adhesive stickers, or Hema-free monomer (Glitter bells) are some other triggers.
How to find your trigger?
- If you think it’s diet/food related:
- Keep a food diary to keep track of what you eat, ingredients, time, etc.
- You can take a skin prick test to see if you are allergic to certain foods
- Go on an elimination diet and watch for patterns
- Common food intolerances: sugar, histamine foods, alcohol/caffeine, dairy
- Vitamins are another way. Use a digital app like Cronometer to track vitamin intake.
- You can take a blood test to see if you are lacking vitamins
- If you think it’s a contact allergy:
- Think back to when it appeared and list all the things you touched with that area of skin today and yesterday.
- Take pictures of the ingredients in all of the products you use such as detergents, cosmetics, soap, shampoos, and household chemicals. See if there are common ingredients, buy products without those ingredients, and see if your skin gets better.
- Use a journal to keep track of what you touch
- You can also ask your doctor for allergy testing
- If you think it’s related to the weather:
- High humidity increases sweating. Keep your place cool with air conditioning or a fan. You can also get a dehumidifier to reduce the moisture in the air.
- Extremely low humidity can dry out your skin and make it harder to heal. Get a humidifier and put it in your room while you sleep. During cold days, wear mittens or put your hands in your pockets to keep the moisture in.
- Keep track of the places you travel to and the weather there.
- If you think it’s related to the dust/mold:
- Clean and vacuum your place frequently. Wear a mask when you clean.
- Remove carpets and curtains. Go for wood floors.
- Get a dehumidifier if you live in a hot climate. Use a hygrometer to make sure the humidity in your home is below 55%. mold and dust mites cannot thrive in low humidity.
- If you have a dust allergy, place a HEPA air purifier in your bedroom. Keep pets outside of the house. For dust mites, get 100% cotton bedsheets and pillowcases and wash them in hot water once a week. Get a humidifier if you live in a dry place as they will help to add moisture to the air and soothe the nose and throat.
- If you have a mold allergy, dry damp areas of the house such as under the kitchen sink, washing machine, etc. Dry water-damaged items within 24 hours. Clean out air conditioners often. Clean out the fridge once a week. Throw away expired food and leftovers.
- If you think you’re sensitive to hard water:
- Go to a hotel or a vacation spot that uses soft water for one to two weeks. See if your skin gets better while you’re there.
- If it does get better, you can install a water softener or a hard water filter in your home, move to a new area that uses soft water, or limit your contact with hard water such as taking short showers.
- Note: A water filter is different from a water softener. While water filters will not turn hard water into soft water, it filters out impurities from hard water like metals and chemicals. It costs around $30-$50 every few months and has helped people reduce their eczema flare-ups.
How to treat pompholyx eczema?
- Learn what your triggers are: firstly, any triggers for a pompholyx flare should be avoided.
- Emollients and potassium permanganate soak: emollients (medical moisturizers) can help with dryness. A wet soak can also be used if your skin is weeping, oozing, and crusting. Usually, a potassium permanganate soak is used under supervision (prescribed as permitabs, which are dissolved in water to the strength of the colour of rose wine) once or twice a week. Soak your hands/feet in this solution (you can use an old bucket or bowl because the solution can stain your skin.) for 15 mins and then rinse it in water with emollients and pat dry. After using the soak, make sure to moisturize your hands/feet. When the acute flare of pompholyx subsidies, the soaks should be stopped after 3-7 days. A leave-on emollient or an emollient soap substitute should be used for washing, and try avoiding detergent hand washes. Bleach baths and Epson baths are some other ways.
- Topical steroids: Topical steroids should be used to treat active eczema and reduce inflammation. It will help to reduce sore, red, and cracked skin. Hands require stronger steroids. so potent topical steroids are prescribed (moderate steroids for children). The treatment is generally for 2 weeks. Topical steroids can make the skin drier, so make sure to apply emollients. Some topical steroids are:
- Clobetasol propionate
- Mometasone
- Clotrimazole
- Triamcinolone
- Betamethasone dipropionate
- Terbinafine
- Elidel and tacrolimus are some non-steroid creams you can try out
- You can google “steroid potency chart” and check which steroid suits you depending on the severity of your skin (after consulting a doctor).
- Oral treatment: for severe pompholyx eczema, a dermatologist is required and he/she will conduct a patch test to check the severity of pompholyx eczema you may have. Treatment may include a course of oral immunosuppressant drugs. Alitretinoin (also known as Toctino) is an oral treatment used for treating severe hand eczema (including pompholyx) that has not responded to potent topical steroids. It helps to reduce inflammation by damping down the response of the immune system. It is a capsule that is taken orally (once a day) for 12-24 weeks.
- Alitretinoin: is a retinoid that is prescribed by a dermatologist who has experience in both severe hand eczema and retinoids. Retinoids could cause birth defects if taken during pregnancy. So you should avoid getting pregnant during treatment and for one month after stopping treatment. You should also avoid breastfeeding while taking alitretinoin and for a month after completing treatment.
- Phototherapy: using either UVB or UVA rays administered by a special hand/foot lightbox, may be recommended if this treatment is available locally. Before the treatment, your hands or feet will be coated in a light-sensitizing solution called psoralen. This treatment will be done 2-3 times a week. It can take a few months until the pompholyx eczema has resolved.
- Duxipent, Eucrisa, and Opzelura: are biologic drugs that can be expensive but can get the job done. You will have to use this for your whole life.
How can you treat pompholyx eczema at home?
- Wash with lukewarm to cool water: Gently pat them dry immediately with a paper towel or a soft towel and then put on moisturizer within 3 minutes to keep the moisture from leaving your skin. Avoid washing your hands as much as possible as It would strip your natural oils and make your skin drier.
- Moisturizers: when you have a flareup, use a thick, greasy moisturizer several times a day. If your hands are sweaty, do not put moisturizer on them as it could make your hands sweat more. Use moisturizer after you wash your hands and on dry areas. When your blisters heal, you can use a lighter, cream moisturizer if you want.
- Gloves:
- White cotton gloves: you can use these for everyday wear and daily chores. This helps the moisturizer sink into the hands/feet and prevents scratching. Make sure to get a few pairs of cotton gloves and change your gloves during the day when you feel them getting wet inside.
- Nitrile gloves: you can use these for washing dishes and gardening. You can wear cotton gloves inside of your rubber gloves or buy gloves with an inner soft lining.
- Disposable gloves: you can wear nitrile gloves with a hair tie on each of your wrists when taking showers. If the water irritates your hands a lot, consider wearing these when you need to use the restroom and throwing them away afterward.
- Alternative gloves: running gloves (may be useful for sleep scratching), tubular support bandages (made of cotton), and white cotton socks
- Antihistamines for sleep: if itchiness is interfering with sleep, you can use sedating antihistamines (they help with sleep rather than actively treat eczema). Some examples are Claritin, Allegra, and Benadryl. Do not take antihistamines in the morning as they can cause drowsiness.
- Treating blisters: large blisters can be drained by using a large sterile needle. Very gently make a jagged tear in the blister (a pin-prick hole won’t be effective as it will seal up very quickly and won’t release any fluid). Make sure to not remove the roof of the blister as it can delay the healing process and might cause infection.
- Use cotton: make sure that your tights, stockings, socks, and gloves are 100% cotton (or silk) as synthetic fibers like nylon are less absorbent than cotton and won’t allow the skin to breathe.
- Bandages: Bandaging (or wrapping) can help to protect the skin. You can also use cotton or silk gloves or socks can be worn. If paste bandages or wet wraps are used, make sure to discuss them with a doctor regarding their suitability, application technique, and how to use them with creams and ointments. Any weeping blisters should be covered with a non-stick dressing (to prevent tearing the blister roof).
- Steroid-impregnated tape: since it is difficult to keep topical steroids on the hands, you can use steroid-impregnated tape which would need to be prescribed by your doctor.
- Hydrocolloid Bandages: if you have painful cracks and fissures post-blister stage, you can try using Extra Thin Duoderm. It is a hydrocolloid dressing that you can cut to shape and put on cracks and fissures. You should speak to your doctor before using duoderm on the areas you treat with topical steroids because when you cover the skin that is being treated with a topical steroid, it will make the steroid more potent.
- Using the right footwear: footwear should be kept dry and must be permeable to the air. Try to avoid plastic or rubber shoes, and any trainers that can cause sweating. Leather linings are more than synthetic.
- Wet wrap therapy: involves applying medication and moisturizer to a flare-up and then wrapping the area with a second layer of dry cloth such as cotton pajamas. The wraps allow the medicine and moisturizer to sink into the skin effectively. This can be before going to sleep and the next day, you will see that the flare-up has reduced.
Other treatments:
- Aloe Vera, manuka honey, oatmeal, and witch hazel can soothe the skin.
- Oils like rosehip seed oil, hemp seed oil, calendula oil, coconut oil, and tea tree oil can help.
- Keratolytic agents like lactic acid, urea, salicylic acid, and sulfur can help.
- AHAs like glycolic acid, lactic acid, citric acid, hydroxycaprylic acid, and hydroxycapric acids can help.
- Diets like low-carb diets, low histamine diets, anti-inflammatory diets, caveman diets, keto diets, carnivore diets, etc can help if you have food allergies. Stick with it for at least two months to see any changes. Consult with your doctor before you decide to take on a diet.
- Supplements like omega-3 supplements, milk thistle, and fish oil might work.
- Fasting is also one way.
- Diluted vinegar soaks (apply white vinegar or cider vinegar soaks for 5-15 minutes. One tablespoon of vinegar in one pint of water. They are mainly used for fungal infections, not dyshidrosis. Vinegar soaks will make your skin very dry and may cause more inflammation. Use this method with caution. If you have open cuts/raw skin, it will burn badly.
- Mouthwash soaks (Listerine) can cause irritation and dry out the skin due to the presence of alcohol. It also contains eucalyptol that can bring temporary relief to the skin but there are more effective and safer alternatives out there like ice packs and coconut oil
- Probiotics can be a great way to boost your immune system and aid the digestive system.
- Popping blisters be a way to relieve the itchiness and prevent the infection if done correctly.
- Using oxybutynin for the treatment of dyshidrotic eczema.
A treatment that has worked for some people:
This particular treatment involves targeting a fungus called candida in the gut.
- Nystatin: Nystatin orally, preferably as a bitter powder (about one-eighth of a teaspoon with a teaspoon of water), 4 million units or 1 million units 4 times a day for 28 days. A second course may be required to kill any spores that have ‘hatched’ to save themselves from the first course of Nystatin. In many countries, Itraconazole is an over-the-counter medication and 200mg daily can be used concurrently with Nystatin.
- Diet: A wheat, sugar, and alcohol-free diet are essential for the best results.
- Alitretinoin: we already talked about it above.
- Vitamin A: it should be taken with a fatty meal.
- Probiotics: Probiotics can also be taken along with this treatment.
The Herxheimer Reaction is a reaction that happens when following the above treatment. If your dyshidrosis gets worse, then the dermatophyte is dtying. This means that the treatment is working and can last for a few days.

How to stop scratching?
Scratching can tear the skin’s surface and prevents moisturizers from working. Continuous scratching and rubbing can cause lichenification, a condition where the skin becomes uneven, thick, and leathery and will clear up when the scratching stops.
The itch-scratch cycle starts when you start to feel itchy and scratch that part of your skin.
Habit Reversal Training
People can form unconscious habits to scratch in certain situations. Many eczema sufferers scratch their hands and feet unconsciously.
This is a simple and free habit reversal therapy you can do at home and is usually used for people with uncontrollable tics, but it can also be applied to people who have itchy eczema.
Objective: To replace damaging habits with new responses
Duration: Do this for at least 6 weeks
Here are the steps:
1) Building awareness: Use a tally counter or a paper tally list to note down every time you scratch.
2) Behavior modification: Replace the scratching habit with a competing response such as shaking your hands for 30 seconds or clenching your fist for 40 seconds. It can be a combination of responses such as clenching your fist for another 60 seconds, deep breathing for 60 seconds, then placing your hands at the sides of your body firmly at waist level.
The new response has to be long enough for the scratching urge to go away. This will break the itch-scratch cycle. If you’re going to be around other people every day, choose a response that people won’t notice.
3) Awareness + behavior modification: Write down all the situations that make you itch and then create individual methods for each situation to avoid scratching yourself.
Ex: If you scratch yourself unconsciously when you drive then the method for this situation is to keep both of your hands on the steering wheel so you can’t use your hands for scratching.
4) Relaxation training: Learn relaxation skills such as deep breathing, mental imaging, and muscle relaxation for stressful situations.
5) Example responses you could use: pumping hands up in the air, doodling/writing in the air, tapping or patting the arm/leg, or deep breathing.
Meditation
There are many different types of meditation, but for this case, let’s focus on mindfulness. Habit reversal training is more effective than this method, but some eczema sufferers have found success with meditation.
This mindfulness is about recognizing your itch, resisting the urge to scratch, and letting it slowly fade away. You will learn that if there is an itching sensation, you do not have to immediately react to it.
Other techniques are body scan guided meditation.
