Baebae-dong Dermatology: Causes and Treatment of Dry Skin—Why Lotion Alone Won’t Solve It
Have you ever felt uncomfortable going out because your face feels tight after washing, and your calves and elbows become covered with white flaky skin? There are also many people who say that even after applying plenty of moisturizing cream, their skin feels tight again after an hour, and by nightfall it becomes unbearably itchy, keeping them awake from scratching. Among the patients I see in the clinic, many dismiss it as “I guess I just have naturally dry skin” and only come in after their symptoms have significantly worsened.
However, dry skin is not simply a state of lacking moisture. Because it is a problem with the skin’s function—where the skin barrier is damaged and cannot properly hold on to moisture—it is difficult to solve fundamentally with moisturizers alone. Today, I’ll explain in detail why dry skin occurs, what symptoms it comes with, and how it is treated in dermatology.
Dry skin is a condition in which the skin barrier breaks down and moisture escapes

The stratum corneum, the outermost layer of our skin, acts as a protective barrier that blocks external irritation and keeps moisture from evaporating from within the skin. When this barrier is healthy, moisture is properly maintained and the skin feels hydrated and supple. But as we age, sebum secretion decreases, and repeated frequent washing, excessive exfoliation, hot showers, and dry indoor environments gradually begin to break down this barrier.
When the barrier is damaged, irritating substances from the outside can enter more easily, and moisture inside the skin evaporates quickly, creating a vicious cycle in which the skin becomes increasingly dry and sensitive. In particular, cold winter winds, low humidity, and excessive heating accelerate this process significantly. In cases of skin conditions such as atopic dermatitis or psoriasis, the barrier function is structurally weakened, so dryness may appear more severely.
If left untreated, itching, flaking, and cracks can develop into dermatitis

The most common symptoms of dry skin are tightness, roughness, and white flaking. If it progresses further, fine cracks can form in the skin, and external irritants penetrate through the gaps, causing redness and more severe itching. Symptoms are often concentrated in areas with fewer sebaceous glands, such as the outer calves, elbows, and the backs of the hands.
The problem is that scratching because it itches further damages the skin barrier, repeating the vicious cycle of worsening inflammation. In severe cases, it can develop into dry eczema or nummular eczema, leading to oozing and crusting. If dry skin is left untreated for a long time as merely a matter of skin type, it can lead to chronic dermatitis, so it is important to begin treatment at the proper time.
In dermatology, treatment focuses on restoring the damaged barrier and calming inflammation

Dry skin treatment is not just about adding moisture; the key is helping the skin regain the ability to retain moisture on its own. First, we accurately check the skin’s moisture condition and the degree of barrier damage using the Markview diagnostic device, then establish a treatment plan. If inflammation is present, medication such as topical steroids or calcineurin inhibitors is used to quickly reduce itching and redness, and LDM ultrasound care is used to stabilize the sensitized skin barrier.
LDM uses alternating ultrasound energy at two frequencies, and because it produces minimal heat stimulation, it can be applied comfortably even to sensitive skin. For patients whose skin regeneration environment has broken down, Pladuo’s nitrogen plasma delivers energy deep into the dermis to create an environment in which the skin can recover on its own. If dryness has persisted for a long time and skin elasticity has also decreased, Virtue RF directly delivers high-frequency energy to the dermis to stimulate collagen production and help firm the skin from within.
The skin needs to be able to retain moisture on its own, not just be covered with moisturizer

Dry skin often becomes chronic before you know it if you keep putting off treatment and thinking it will improve when the seasons change. Once the skin barrier has broken down, it becomes increasingly sensitive to external conditions, and the skin quickly becomes dry again no matter how diligently you apply moisturizer. Home care is also important. Take showers briefly in lukewarm water for no more than 10 minutes, and apply plenty of moisturizer within 3 minutes of towel-drying.
It is good to keep indoor humidity at 50 to 60 percent and reduce the use of hot water and irritating cleansers. However, if the barrier is already damaged, there are limits to recovery through lifestyle habits alone. Work out a treatment plan with a dermatologist so your skin can regain the ability to hold on to moisture by itself. I will carefully help you return to comfortable, hydrated skin.
