[Health Column] Adult Atopic Dermatitis: What Causes It to Suddenly Develop After Becoming an Adult?

 

Hello, this is Dr. Park Chi-young, Chief Director of Saenggi Korean Medicine Clinic Gangnam Station Branch.

 

“My skin was fine when I was young, so why did I suddenly develop atopic dermatitis after becoming an adult?” This is a question frequently asked by adult patients in the clinic.

 

While adult atopic dermatitis can persist from childhood, there are also cases where the problem is recognized for the first time as symptoms become prominent after adulthood. Today, I will explain how to understand the causes of adult atopic dermatitis and what factors to consider when the condition recurs.

 

I. What is adult atopic dermatitis?

Adult atopic dermatitis refers to atopic dermatitis that appears or persists during adulthood. It involves a complex interplay of various factors, including impaired skin barrier function and abnormal immune responses, and may manifest as recurring itching, dryness, and redness of the skin.

 

Some people who experienced atopic symptoms during childhood may experience them again as adults, while others may not have recognized distinct symptoms before but develop dermatitis after becoming adults.

 

Symptoms may appear particularly on the face, neck, and the creases of the arms and legs; continued scratching due to itching can also lead to changes such as the skin becoming rough and thickened. Therefore, rather than making a diagnosis based solely on symptoms, it is necessary to comprehensively assess the timing and location of onset, as well as the recurring pattern.

If itching recurs, changes such as the skin thickening, becoming rough in texture, or darkening in color may remain. This is called lichenification or hyperpigmentation; rather than merely temporarily alleviating the visible rash A plan to properly treat inflammation while managing the skin barrier and aggravating factors. This is also the reason why it is necessary.

 

 

 

II. Causes of Adult Atopic Dermatitis: Why Does It Suddenly Appear After Becoming an Adult?

It is difficult to pinpoint a single cause for adult atopic dermatitis. This is because atopic dermatitis is a disease influenced by a complex interplay of factors, including the skin barrier, immune response, genetic predisposition, and environmental influences.

 

As you become an adult, your living environment changes significantly. Sleep deprivation due to work or childcare, along with stress and overwork, can occur, and there are also many factors that can affect your skin condition, such as frequent drinking, irregular lifestyles, and changes in seasons and indoor environments.

 

For this reason, even if you feel it “appeared suddenly,” consider not only your recent skin condition but also Lifestyle changes and aggravating factors around the time symptoms started It is necessary to examine this together. In particular, repeatedly scratching when the skin is dry can further damage the skin barrier, leading to a vicious cycle where itching worsens again.

 

The indoor environment also has a greater impact than you might think. Spaces where heating or cooling is left on for extended periods tend to dry out the air, and dry skin can react more sensitively to the same irritations. An environment where hands are washed frequently or cleansers are used repeatedly can also place a burden on the skin barrier.

 

Since irritation that was fine yesterday can become a problem today, it is best not to jump to conclusions about the cause based on a single experience. Instead, if you look for patterns that repeat over several days, you will find clues for management.

itch	Area and intensity (0~10), time of worsening
sleep	Time of falling asleep, number of times woken up by itching
Washing · Moisturizing	Water temperature and time, and the time when moisturizer was applied
Lifestyle changes	Overwork · Alcohol consumption · Changes in seasons · Indoor heating and cooling

 

III. How does Korean traditional medicine approach adult atopic dermatitis?

In Korean medicine, even with the same diagnosis of atopic dermatitis, the direction of treatment is assessed differently depending on whether heat sensation, redness, and oozing are prominent, whether dryness, scaling, and skin thickening are the central features, and whether the condition is in the acute or stable phase.

 

We examine digestive status, sleep, stress, and changes such as menstruation, childbirth, and menopause along with the timing of symptoms to review herbal medicine and topical treatments tailored to the patient's constitution and disease stage. The key is not just to look at the skin, but to examine when and under what conditions symptoms recur.

 

 

Even for the same individual, the focus differs between the acute phase, when symptoms are severe, and the relatively stable phase. During the acute phase, the emphasis is on alleviating inflammation and itching, whereas during the stable phase, the focus of management shifts toward moisturizing, maintaining sleep and daily routines, and detecting signs of recurrence early.

 

When considering herbal medicine, you must disclose your pregnancy or breastfeeding status, any underlying medical conditions, and any medications or health supplements you are currently taking, and confirm the compatibility of concurrent treatments. Rather than arbitrarily discontinuing your existing prescription, it is safer to share your treatment details with your medical team to make adjustments.

 

IV. What should be checked when considering treatment for adult atopic dermatitis?

If you frequently wake up from sleep due to itching, or if skin symptoms affect your work and daily life, or if symptoms such as redness, oozing, or scaling recur, it is advisable to have your condition accurately checked by a medical professional. Since there are other skin conditions that look similar, you should avoid self-diagnosing that you have adult atopic dermatitis.

 

The management process can be divided into three stages: the period when uncomfortable symptoms are prominent, the period when the skin is relatively stable, and the subsequent stage of managing factors that cause recurrence. In particular, keeping a record of situations where your skin deteriorates, such as seasonal changes, overwork, or increased stress, helps you identify changes more quickly.

 

The duration of treatment varies from person to person depending on the duration of symptoms, current skin condition, previous treatment history, and lifestyle. When selecting a treatment method, rather than explanations that guarantee specific results or durations Whether the current condition and treatment history are sufficiently verified and a step-by-step management plan is presented It is recommended that you take a look at this.

When choosing a medical facility, check if they inquire not only about your current skin condition but also about past treatments, aggravating factors, sleep and lifestyle, and medications you are currently taking. The longer a symptom has persisted, the more difficult it is to determine a course of action based solely on the current state of your skin.

Therefore, rather than narrowing down the cause to a single factor Identifying the conditions that worsen my skin and reducing them one by one. This is a realistic starting point.
