Are there also itching and pain?

If dryness and cracking cause itching, stinging, or severe skin tightness, pain may occur when moving.

Is ichthyosis always hereditary?

Most are related to genetics, though the transmission methods vary, and there are acquired types that occur in adulthood due to other health issues or medications.

Current discomfort

Senile and Xerotic Pruritus, when was it most uncomfortable?

If your current discomfort is similar to the experiences below, we can determine during a medical evaluation whether it is senile and xerotic pruritus or another skin issue.

Those who have more dryness, fine scales, and scratch marks than red rashes
Those whose itching worsens after a hot bath and who wake up at night despite moisturizing
Those with diabetes, kidney, liver, or thyroid diseases, or those taking multiple medications

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 GuideThings to check when itching prevents sleep at nightFirst, check if the swollen areas generally fade within a day, or if rough and cracked skin remains for several days. If the wheals have subsided but you continue to wake up, record both the changes in the wheals and the number of times you woke up. If rough skin and scratch marks remain, the cycle of dermatitis and the itch-scratch cycle must be examined together. Even if there are few skin changes, please seek medical evaluation if generalized itching is accompanied by jaundice, weight changes, or fever.Medical Evaluation GuidePrepare for your visit with skin photos, symptoms, and medications usedRather than a single photo, please prepare a chronological record of the date the symptoms first appeared, the timing of when they disappear and reappear, itching and pain, and the medications used and your reactions to them. It is helpful for the medical evaluation to take photos of the same area from the same distance during both normal states and when symptoms are most severe.Medical Evaluation GuideRecurring skin symptoms: When should you start Korean medicine treatment together?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 guide for senile and xerotic pruritus

Dry skinDry skin can manifest as a feeling of tightness after washing, a rough texture, flaking, and itching. It is influenced not only by a simple lack of moisture but also by dermatitis, age, and environmental factors.PruritusPruritus refers to itching. This can include itching with distinct skin lesions as well as itching with few visible changes.Yin-Blood DeficiencyYin-Blood Deficiency does not mean the same thing as a general test result showing a lack of blood. It is a Korean medicine term used to interpret various findings together, such as skin dryness, chronic itching, sleep patterns, and energy levels.

When herbal medicine treatment is the primary focus

If senile or dry pruritus worsens even after treatment

Even if there is little visible rash, itching can significantly disrupt sleep and concentration. Based on a necessary evaluation of systemic causes, herbal medicine treatment can be the primary focus to address nighttime worsening and the cycle of dryness and fatigue.

Before the consultation

We ask where it appeared and when it worsened again

We examine the itchy areas and timing, skin changes before scratching, dryness and lichenification, as well as systemic changes including sleep, bowel movements, urination, and current medications.

During treatment

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

We compare the frequency of waking up during the night, scratching wounds, the duration of itch-free time, and the recovery of daily activities.

Treatment sequence

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

If there are causes that require immediate priority, such as infection or rapid worsening, those treatments come first. Subsequently, for herbal medicine treatment, we determine the primary goal of recovery by examining current discomfort, recurring patterns, sleep, digestion, and fatigue, and coordinate the sequence with necessary dermatological treatments.

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

Senile and dry pruritus: symptoms and when to seek prompt medical evaluation

Senile and xerotic pruritus is a condition where the skin thins with age and the ability to retain moisture and sebum decreases, leaving the calves, arms, and back rough and itchy. Hot baths, strong soaps, and dry heating can worsen the condition, but new medications and liver, kidney, thyroid, diabetes, or blood disorders must also be checked. Rather than repeating moisturizing alone, the distribution of itching, quality of night sleep, skin wounds, and systemic changes are examined.

Director Choi Yeon-seung's Clinical Perspective

How is the direction of herbal medicine treatment determined for senile and dry pruritus?

For senile pruritus, we do not unconditionally lower heat. After first checking current medications and systemic causes, we perform a pattern identification to see if there is severe skin dryness, coldness, and fatigue; if there is afternoon/nighttime deficiency heat and night sweats; or if digestion and energy are low, causing wounds to heal slowly.

Changes to be confirmed in this treatmentThe goal is to reduce nighttime itching and new scratch wounds, minimize skin cracking, and increase the number of nights spent sleeping comfortably.

Points to distinguish first

How to distinguish senile and xerotic pruritus from similar-looking skin diseases

What to look for on your skin now

A representative pattern is the persistence of very dry, thick, and rough scaly skin over a wide area.

When did it start and how has it recurred?

Senile and xerotic pruritus is a condition where the skin becomes thinner with age and the ability to retain moisture and sebum decreases, leaving the calves, arms, and back rough and itchy. Hot baths, strong soaps, and dry heating can worsen the condition, but new medications and liver, kidney, thyroid, diabetes, or blood diseases must also be checked. Rather than simply repeating moisturizing, we examine the distribution of itching, night sleep, skin wounds, and systemic changes. This information is reviewed again when determining the current stage and treatment boundaries of senile and xerotic pruritus.

Check what changes during treatment

Depending on the type, blisters, redness,skin tightness· and may be accompanied by hair loss, hearing, or vision problems.

Why does it keep getting worse?

Reasons why senile and xerotic pruritus persists or recurs

First, we rule out new systemic causes

We check for medications, liver, kidney, thyroid, diabetes, and blood disorders, as well as test results.

Reduce actual irritation from bathing, heating, and soap

We do not simply add prescriptions while maintaining a lifestyle that further dries out the skin.

We also monitor if you are waking up less and if scratches are healing

Nighttime awakenings and new scab· infection, and periods of comfort.

Thick, brown plaques can become fixed in areas that are repeatedly touched, such as the ankles. We examine the timing to determine whether the itching came first or if the habitual scratching started first.

Things to prepare before your visit

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

Skin Changes

As the ability to retain moisture and sebum decreases, the calves, arms, and back may become rough and develop fine cracks.

Bathing and Heating

We check if hot water, long baths, strong soaps, and dry indoor environments are increasing the itching.

Medications and Systemic Diseases

We check for new medications, changes in diabetes, liver, kidney, thyroid, or blood disorders, and recent test results.

Changes to monitor during treatment

What changes should I monitor during treatment?

Photos of itchy areas, dry skin, and wounds

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.

Medications, underlying conditions, and recent blood tests

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

Bathing, heating, moisturizing, number of nighttime awakenings, appetite, and energy levels

Please also include the dates of any medications, ointments, or procedures you are currently using. This makes it easier to compare what led to improvement or worsening.

When planning herbal medicine treatment

For senile or dry pruritus, the direction of Korean herbal medicine treatment is determined based on the symptoms currently most prominent.

Even among cases characterized by dryness, the proportions of cold sensations and dehydration, afternoon or nighttime heat, and decreased appetite or energy vary.

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 · Blood Deficiency and Wind-Dryness (Dehydration Type)

When calves and arms are rough and itching worsens at night

Primary skin observations: We look for fine dead skin, cracks, and dry scratch marks.
Overall body condition to check alongside skin: We check for dryness of the skin and mouth, as well as cold sensations.
Primary considerations for herbal medicine prescription: The focus is on nourishing the blood, moisturizing dryness, and restoring the skin barrier.

02 · Yin Deficiency with Internal Heat (Nighttime Type)

When there is a burning sensation and night sweats in the afternoon or at night

Primary skin observations: We observe if heat sensations and scratch wounds increase without severe redness.
Overall body condition to check alongside skin: We ask about dryness of the mouth and eyes, shallow sleep, and night sweats.
Primary considerations for herbal medicine prescription: We replenish bodily fluids while regulating deficiency heat and sleep.

03 · Qi and Blood Deficiency (Poor Recovery Type)

When energy is low and wounds heal slowly

Primary skin observations: We look for scabs, bruising, color changes, and symptoms suspected of infection.
Overall body condition to check alongside skin: We check for decreased appetite, dizziness, and fatigue.
Primary considerations for herbal medicine prescription: We reinforce Qi, blood, digestion, and skin recovery.

04 · Damp-Heat (Active Inflammation Type)

When redness, heat, oozing, and swelling are prominent

Primary skin observations: We observe the redness, heat, oozing, and the rate of spreading in skin changes associated with senile or dry pruritus.
Overall body condition to check alongside skin: We check if itching increases and sleep is disrupted after exposure to heat, sweat, or humid environments.
Primary considerations for herbal medicine prescription: We first reduce the burden of active inflammation, damp-heat, and intense itching.

How is the herbal medicine prescription adjusted?

Systemic causes and medications are checked first
New itching is not dismissed as simply a result of aging.
Reduce environmental factors that dry out the skin
Specifically adjust bathing, soap use, heating, and moisturizing.
Monitor sleep and wound healing together
Check if nighttime awakenings and new wounds are decreasing simultaneously.

When should I consider Korean herbal medicine treatment?

When generalized itching recurs every night despite cause evaluation and moisturizing
When daily life is disrupted due to increased scratch wounds, bruising, and sleep disturbance
When dryness, cold sensitivity, fatigue, and poor digestion fluctuate along with itching

What will be asked during the medical evaluation?

Photos of the itchy areas, skin dryness, and wounds
Current medications, underlying conditions, and recent blood test results
Bathing, heating, moisturizing habits, number of nighttime awakenings, appetite, and energy levels

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 Senile and Xerotic Pruritus

What does ichthyosis skin look like?

The skin may appear very dry, rough, and have thick, scale-like keratin on the arms, legs, torso, face, or across the entire body.

Is there also itching and pain?

Itching or stinging may occur due to dryness and cracking, and severe skin tightness can cause pain during movement.

Why can hot days be dangerous?

In some severe types, reduced sweating makes it difficult to lower body temperature, so overheating, dizziness, and lethargy must be monitored closely.

When should I suspect an infection?

Same-day medical evaluation is required if cracked areas suddenly become painful and hot, or if pus, spreading redness, or fever occurs.

Is all ichthyosis hereditary?

Most are related to genetics, though the mode of inheritance varies; there are also acquired types that develop in adulthood due to other health issues or medications.

Can it suddenly develop in adults?

Yes. If it first appears in adulthood, acquired causes, including health issues and medications, are evaluated.

How is it different from general dryness?

A dermatologist will evaluate the age of onset, distribution, characteristic long-lasting scales, thickening, and accompanying issues.
