Today, I’d like to talk about a major skin condition that many people have experienced at least once, or have seen in someone around them, but often misunderstand:
atopic dermatitis.
Have you ever heard things like:
“Isn’t atopy just caused by dry skin?”
“It starts when you’re young and gets better as you grow up~”
However, medically speaking, atopy is clearly a skin condition that is different from simple dryness or temporary itching.
And once atopic dermatitis develops, severe itching and cracked skin can occur, leading to intense physical discomfort.
In particular, children may have trouble sleeping because they scratch all night, have difficulty concentrating during the day because of itching, and even experience a drop in self-esteem.
Even so, many people still think this way:
“Maybe it’ll get better if I just scratch it a little.”
“It’ll be fine if I apply moisturizer.”
“Let’s just buy a famous ointment and use it.”
But this is like pouring a cup of water on a forest that is already on fire.
The outside may calm down for a moment, but the inside is still burning.
Today, at the National Assembly Station Dermatology Clinic, I’d like to share a few things that atopic dermatitis patients should definitely know.
- Causes of atopic dermatitis
- Incorrect ways of using atopic dermatitis treatments
- Treatment with atopic dermatitis steroid ointment

Why does atopic dermatitis occur?
Atopic dermatitis is a skin condition caused not by a single reason, but by a tangled mix of multiple factors.
✔️ Genetic factors
If even one parent has a history of atopy, the child’s likelihood of developing atopy may increase.
In particular, if both parents have allergic conditions, the child is more likely to experience similar conditions.
✔️ Problems with the skin barrier
Healthy skin acts like a shield that protects the body from external irritation.
However, in atopic dermatitis patients, the skin barrier is weak, so moisture escapes easily and external irritants can penetrate easily.
✔️ Environmental irritants
Fine dust, yellow dust, pollen, house dust mites, pet hair, detergent, perfume, and even temperature changes, sweat, friction, and humidity can all trigger or worsen atopic dermatitis.

Would showering more often help improve atopic dermatitis symptoms?
Many atopic dermatitis patients shower frequently.
I really understand that feeling.
We all tend to think of “washing” as a symbol of cleanliness and recovery.
But for atopic skin, frequent showering can be more harmful than helpful.
Because atopic skin already has a weakened skin barrier, showering itself can become another source of irritation.
In particular, frequent showering repeatedly washes away the skin’s natural moisturizing layer, which can make the skin even drier and more sensitive.
Also, showering with hot water or using exfoliating towels, scrubs, or strong body washes can cause the skin barrier to break down rapidly.
Therefore, it is better to shower once a day for no more than 10 minutes, and to keep the water temperature lukewarm.
In addition, applying moisturizer within 3 minutes after showering can help prevent moisture loss.

How should atopic dermatitis ointment be used?
Steroid ointments are mainly used to treat atopic dermatitis.
However, many people feel a great deal of concern about using steroid ointments.
The expected effect of steroid ointment can vary greatly depending on how, when, and how much it is used.
First, atopic dermatitis is a condition in which inflammation repeatedly occurs on the skin.
Steroid ointment is a treatment that can help suppress this inflammatory response.
And because this ointment is divided into 1 to 7 grades depending on its strength, and is prescribed according to the area of use, age, and skin condition, the likelihood of side effects can be said to be extremely low.
However, excessive use of steroid ointment can cause side effects such as skin atrophy and blood vessel dilation.
Therefore, when using steroid ointment, it is advisable to strictly follow the amount instructed by the medical staff.

Atopic dermatitis is not simply a skin problem, but a chronic inflammatory condition that deeply affects quality of life.
However, if detailed diagnosis and treatment are started early, you can expect to reduce discomfort and regain healthy skin.
Most importantly, do not judge the condition on your own; receive professional diagnosis and personalized treatment.
So if you are feeling stressed because of atopic dermatitis symptoms, I recommend visiting the hospital as soon as possible to receive an appropriate diagnosis.
