Where do dyshidrosis blisters mainly appear?

Small, deep blisters mainly appear on the palms, sides of the fingers, soles of the feet, and toes. If they spread widely to other areas or persist on only one side, other conditions are evaluated.

Do dyshidrosis symptoms remain even after the blisters disappear?

As blisters dry, the skin may peel, become dry, or develop deep cracks. If this repeats, the skin can thicken, and using your hands or feet may become painful.

Current discomfort

Dyshidrotic Eczema: When was it most uncomfortable?

If your current discomfort resembles the experiences below, we can determine step-by-step during a medical evaluation whether it is dyshidrotic eczema or another skin issue.

Those whose sleep is disrupted by nighttime itching of blisters on the sides of the fingers or palms
Those who experience severe itching or burning before blisters appear, followed by skin peeling after they dry
Those who are concerned about infection or other skin diseases due to cracking, oozing, or crusting

Discomfort that persists after tests and treatment

Does the same area become itchy again after you stop using ointments or medication?

The same area may become itchy and red again after a period of improvement while using medication. This does not mean that your previous treatment was ineffective. During your consultation, please tell us how much you improved, when it worsened again, and if the itching has affected your sleep or daily life.

We establish a treatment plan based on your skin condition and the pattern of recurrence. If there are causes that need to be addressed first, such as an infection or rapid worsening, those treatments take priority. Korean herbal medicine treatment considers remaining itching, heat sensations, and oozing, as well as sleep, digestion, and fatigue, to set primary goals and progress criteria; the sequence of necessary dermatological treatments is also adjusted based on your actual response. Lifestyle management is tailored to support treatment goals and minimize skin irritation.

Medical Evaluation GuideDistinguishing between rashes that disappear within hours and dermatitis that lasts for daysFirst, observe whether swelling in the same area generally fades without leaving a mark within a day, or whether it stays for several days, leaving dead skin, oozing, or scabs. Wheals that disappear and reappear in different locations suggest urticaria (hives), while long-lasting surface changes suggest other types of dermatitis; however, a diagnosis requires looking at the overall progression.Medical Evaluation GuideWhen your skin changes after using new cosmetics, shampoo, or detergentsRather than attributing the cause to a single new cosmetic product, please record the affected areas, the date you started using it, whether the product was rinsed off or left on the skin, and any substances you come into contact with through your occupation or hobbies. Sensitive areas such as the eye area and face can also be affected indirectly through substances on your hands or in the air.Medical Evaluation GuideRecurring skin symptoms: When should you start Korean medicine treatment alongside your current care?If the same area recurs even after necessary treatment, or if itching continues to interfere with your sleep, work, or school life, herbal medicine treatment can help manage the recurrence interval and the burden on your daily life. For infections, sudden worsening, or new skin changes of unclear origin, we will first connect you with the necessary tests before proceeding with the treatment sequence.

Terms used in the dyshidrotic eczema guide

VesicleVesicles refer to small blisters. Since causes vary, including dyshidrosis that forms deeply on the sides of fingers, contact dermatitis, or infections, we examine the location, pain, itching, and whether they appear in clusters.FissureFissures are a state where the skin is cracked, creating gaps, which can cause pain and bleeding on the hands, feet, or in skin folds.Damp-HeatIn skin care, Damp-Heat is used to describe a pattern characterized by significant oozing, redness, and prominent feelings of heat and itching. It does not refer to a specific bacterium or test value.

When herbal medicine treatment is the primary focus

If dyshidrotic eczema worsens again even after treatment

If the cycle of deep blisters on the hands and feet drying, peeling, and cracking repeats, managing only the affected area may leave a burden on your daily life. By dividing the changes into the vesicle stage and the dryness/fissure stage, the recurrence cycle can be managed, centered on Korean herbal medicine treatment.

Before the consultation

We ask where it appeared and when it worsened again

We examine the depth of the vesicles, feelings of heat, oozing, subsequent dryness and fissures, as well as sweat, stress, sleep, and the timing of recurrence.

During treatment

We check if not only the itching, but also sleep and daily life are improving

We compare the interval at which new vesicles appear, the degree of cracking and pain, limitations in the use of hands and feet, and the recovery period.

Treatment sequence

We set the goals for herbal medicine treatment by identifying the problems that need to be resolved first

If there is a cause requiring treatment first, such as an infection or rapid worsening, treat it first. Subsequently, herbal medicine treatment focuses on recovery by considering current discomfort, recurring patterns, sleep, digestion, and fatigue, while coordinating the sequence with necessary dermatological treatment.

While reducing aggravating factors through lifestyle management, herbal medicine treatment determines the initial target by analyzing the pattern of lesions, sleep, digestion, and fatigue through pattern identification (Byeonjeung). Necessary skin treatments are continued in accordance with the progress.

Points to check first

Dyshidrotic eczema: Symptoms and when to seek prompt medical evaluation

Dyshidrotic eczema is a type of eczema characterized by clusters of small, deep blisters on the palms, sides of fingers, soles, and toes, which are very itchy or burning. itching·Tingling may start before the blisters appear, and during the 3 to 4 weeks while the blisters dry, the skin may peel, become dry, and crack deeply. However, not all blisters on the hands and feet are dyshidrotic eczema; if they appear for the first time, are distinct on only one side, or spread to other areas, they must be distinguished from contact dermatitis, athlete's foot, or infections at a dermatology clinic. If there are yellow crusts, pus, rapidly spreading redness with heat and pain, or a fever, prompt medical evaluation is a priority over self-care.

Symptom stages and next steps

Small vesicles, recovery phase cracks, and suspected infection symptoms are examined differently

Do not confirm a diagnosis based on appearance alone; check the location, recurrence cycle, pain, and heat sensation together.

Current Appearance	Points to Check	Next action
Deep, small vesicles on the sides of fingers or palms	Whether severe itching or burning occurred first	Do not scratch or pop them; seek evaluation by a dermatologist.
Blisters merge to form a large blister	Whether it is difficult to use hands/feet or to walk	Seek prompt medical evaluation if the area is large or pain is severe
Peeling, dryness, or deep cracks following blisters	Whether new blisters continue to appear	Moisturize, avoid irritation, and re-evaluate treatment
Yellow crusts, pus, spreading erythema, and heat sensation	Whether pain, swelling, or fever are present	Seek prompt medical evaluation to check for infection
Persistent scaling or blisters on only one foot	Toenail changes · Scaling between the toes	Examination for other conditions such as athlete's foot

Director Choi Yeon-seung's Clinical Perspective

Dyshidrotic eczema: How is the direction of herbal medicine treatment determined?

If there are acute changes such as pus, yellow scabs, spreading heat sensation and pain, fever, large blisters, or changes in mucosal skin, dermatology or emergency evaluation and necessary treatment for infections or blistering diseases take priority over Baekrokdam Korean herbal medicine treatment. If small blisters and cracking repeat chronically despite maintaining diagnosis and standard topical treatments, please record your exposure to water, detergents, gloves, and sweat, as well as nighttime itching and changes in hand/foot usage, to consult on the goals of Korean herbal medicine treatment.

Changes to monitor during this consultationThe goal is to reduce the frequency of new blisters and increase the interval between recurrence and the days you can use your hands and feet without cracking.

What to distinguish first

How to distinguish dyshidrosis from similar-looking skin diseases

First, check whether there is pain, pus, a fever, or blisters with a different appearance.

Check for unilateral distribution, pus, warmth, fever, widespread blisters, and mucosal changes, and do not delay necessary dermatological examinations and treatment.

Distinguish between when new blisters appear and when the skin peels and cracks

Specifically identify the current skin stage by recording itching before blisters, the number of new blisters, and cracking and pain after they dry.

Check the interval between new blisters and the days when your hands and feet feel less uncomfortable

Do not arbitrarily stop using prescribed topical medications; observe if the number of days without new blisters changes in relation to sleep, typing, water-related work, or walking.

Why does it keep getting worse?

Reasons why dyshidrosis persists or recurs

Please keep a separate record of when new blisters appear

During the acute phase, when the sides of the fingers sting and itch followed by an increase in blisters, herbal medicine is adjusted based on the number of new blisters, heat sensation, and oozing.

After drying, we also examine skin cracking and how the hands and feet are used.

Once blisters dry, peel, and crack, it becomes difficult to grip objects or walk. During the recovery phase, the standard for recovery is whether the skin stops reopening, alongside moisturizing.

We examine sweat and heat in the hands and feet, as well as changes in the entire body

We determine the proportion of body heat and damp inflammatory responses by checking if symptoms worsen when the inside of gloves becomes hot and wet, if the hands and feet are cold but only the blistered areas are hot, or if new blisters increase after lack of sleep, digestive discomfort, or fatigue.

Things to prepare before your visit

What photos and records should I prepare before the medical evaluation?

Please prepare the date and photos of the area where the blisters first appeared, information on nighttime itching, presence of discharge or pus, exposure to water, detergents, gloves, or sweat, and your current topical medications and medical evaluation results.

First, there is intense itching or stinging

Itching, burning, or a piercing sensation may begin before blisters are visible. Scratching increases the risk of wounds and infection.

Multiple small blisters appear on the hands and feet

Fluid-filled blisters that seem deeply embedded appear on the palms, sides of the fingers, soles, and toes. If several merge, they may look like one larger blister.

Once blisters dry, dead skin and cracks remain

Generally, over several weeks, the blisters dry and the skin peels and becomes dry. Deep cracks can cause pain when gripping objects or walking.

Changes to monitor during treatment

What changes should I monitor during treatment?

Number of new blisters per day and their location

Please record when it started and how it has changed, including the dates. To make it easier to compare before and after, take photos of the same area from a similar distance and under similar lighting.

Number of days it took for peeling and cracks to recover after the blisters

Please leave a brief note. Compare not only the visible changes but also whether your sleep, pain, and daily life have become less uncomfortable.

Whether new blisters appeared after contact with water, wearing gloves, sweating, or lack of sleep

Please also note the medications and ointments you are currently using, along with the dates when you underwent any procedures. This makes it easier to compare what led to improvement or worsening.

When planning herbal medicine treatment

For dyshidrotic eczema, the direction of herbal medicine treatment is determined based on your current prominent symptoms

Dyshidrotic eczema often recurs if treatment is only provided for the few days when blisters are visible. We adjust the prescription by observing at which stage tingling and heat (before blisters), oozing (after blisters burst), dead skin and cracking (after drying), or hand/foot sweat and stress overlap.

Pattern identification (Byeon-jeung) in Korean medicine is not about giving a different name to a disease. Multiple patterns can overlap in one person, and as the skin changes, for example, as oozing and heat decrease and dryness or cracking remain, the prescription is adjusted accordingly.

01 · Spleen-Stomach Damp-Heat · Blister Active Phase

When hands and feet feel hot and small blisters increase rapidly

Primary skin observations: We look for transparent blisters on the sides of fingers, palms, or soles, along with redness, heat, severe itching, and oozing.
Overall body condition to check alongside skin: We check if symptoms worsen after hot and humid days, wearing gloves, or exercising, and if there is sweating, bloating, or a feeling of heaviness in the body.
Primary considerations for herbal medicine prescription: To reduce new blisters and moist inflammation, we focus on clearing heat and removing dampness to lower heat and humidity.

02 · In-Depth · Tension-Induced Aggravation

When tingling and blisters begin after stress

Primary skin observations: We look for burning or piercing itching at the fingertips and consecutive blister formation after meetings, exams, or insomnia.
Overall body condition to check alongside skin: We ask if difficulty falling asleep, heat in the upper body, heart palpitations, and tension overlap with the onset of skin symptoms.
Primary considerations for herbal medicine prescription: We increase the focus on clearing the heart and stabilizing the mind to lower surging heat and nervous itching and to restore sleep.

03 · Blood Deficiency and Wind-Dryness · Recovery Phase

When blisters dry up, peel, and crack deeply

Primary skin observations: Even if blisters have decreased, we check if dead skin, peeling, cracking, or bleeding remain and if cracks reopen when using the hands.
Overall body condition to check alongside skin: We check for dry skin, a feeling of coldness, fatigue, and whether it takes a long time for wounds to heal.
Primary considerations for herbal medicine prescription: Instead of continuing to only lower heat, we shift the focus of the prescription to nourishing the blood, moisturizing dryness, and recovering the skin barrier.

04 · Cold-Heat Imbalance · Poor Circulation

When hands and feet are cold, but only the skin changes are hot and recurring

Primary skin observations: We look for whether the hands and feet are usually cold and pale, while only the areas where blisters appear are red and hot.
Overall body condition to check alongside skin: We ask if there is a sudden increase in hand and foot sweat when tense or entering a warm place, along with a feeling of coldness, numbness, and fatigue.
Primary considerations for herbal medicine prescription: Rather than a prescription that simply cools everything, we balance the overall body coldness with local heat and sweat regulation imbalances.

How is the herbal medicine prescription adjusted?

We first reduce the active phase where new blisters form
The proportion of heat-clearing, dampness-removing, and tension-regulating treatments is determined based on the level of tingling, heat sensation, and the number of new blisters.
The focus of the prescription shifts the moment the blisters dry
Once discharge stops and peeling or cracking remains, the proportion of dampness removal is decreased, and moisturizing and barrier recovery are added.
We also monitor the interval between recurrences, considering the season and the use of hands and feet
Even if you cannot completely avoid gloves, water work, or exercise, we check if fewer new blisters appear and if the number of days you can use your hands and feet without cracking increases.

When should I consider Korean herbal medicine treatment?

When using topical agents, if blisters dry but reappear within a few weeks
When using your hands or walking is painful due to cracking
When symptoms recur every season despite reducing exposure to water, detergents, gloves, and sweat

What will be asked during the medical evaluation?

The number of new blisters appearing per day and their location
The number of days it takes for peeling and cracking after blisters to heal
Whether new blisters appeared after water work, using gloves, sweating, or lack of sleep

Things to prepare before the consultationPlease prepare the date and photos of the area where the blisters first appeared, information on nighttime itching, presence of discharge or pus, exposure to water, detergents, gloves, or sweat, and your current topical medications and medical evaluation results.

If pus, pain, or redness spreads rapidly, or if you have a fever, lesions inside the eyes or mouth, shortness of breath, or sudden facial swelling, please visit a dermatology clinic or seek emergency care first. After confirming that such urgent situations are not present, Baekrokdam provides herbal medicine treatment for chronic and recurring skin diseases.

Frequently Asked Questions

Frequently Asked Questions about Pompholyx

Where do dyshidrosis blisters mainly occur?

Small, deep blisters mainly appear on the palms, sides of the fingers, soles, and toes. If they spread widely to other areas or persist on only one side, other conditions are checked.

Do dyshidrosis symptoms remain after the blisters disappear?

As the blisters dry, the skin may peel, become dry, or develop deep cracks. If this repeats, the skin may thicken, and pain may occur when using the hands and feet.

Is it an infection if there is discharge from pompholyx blisters?

Discharge alone does not confirm an infection, but if there are yellow crusts, pus, spreading redness with heat, pain, or fever, a bacterial infection must be promptly checked.

Is pompholyx caused by excessive sweating?

While excessive sweating and damp hands or feet can worsen the condition, blocked sweat glands are not the confirmed cause.

Could a metal allergy be the cause?

Hypersensitivity to nickel or cobalt may be involved. A dermatologist evaluates the relationship between exposure and recurring symptoms.

Is stress the cause?

Stress may be a factor in worsening or triggering the condition, but a patient's emotions alone are not viewed as the sole cause.

Should I also check for athlete's foot?

If foot peeling and itching occur together, testing is considered to determine if it is a reaction related to a fungal infection.
