Do you rush to find toner and lotion because your face feels like it is being pulled tight after washing? Or does the makeup you carefully applied in the morning start cracking and lifting by lunchtime, making you afraid to look in the mirror? Patients with dry skin whom I meet in the consultation room always share similar complaints. “Even if I try all the moisturizing creams and oils people recommend, it only works for a moment and my skin quickly gets dry again.” “My skin feels not just rough, but also stings and itches.”

Many people think that if their skin is dry, they simply lack “moisture,” so they drink lots of water or spray mist frequently. But no matter how much water you pour in, it is useless if the container has holes, right? Severe dry skin is not just a lack of water; it is a state in which the “skin barrier” that holds in moisture has broken down. Today, I’ll explain how to care for dry skin that leaks moisture like a bottomless container, and the dermatological treatments that help hydration build up from within rather than just making the surface look greasy.

A strong skin barrier is necessary to protect moisture

The outermost layer of our skin, the stratum corneum, has a structure like bricks and mortar. If the skin cells are the bricks, the lipids (ceramides, cholesterol, and fatty acids) that tightly fill the gaps between them act like mortar. This structure must be strong for moisture inside the skin to stay from evaporating and for external irritants to be blocked from entering.
�
However, in dry skin, there is a lack of these lipid components that serve as the “mortar,” so the space between the bricks becomes loose. With a weak protective barrier, moisture keeps evaporating, and the skin is exposed defenselessly to irritants like cold wind and fine dust, becoming sensitive skin that stings and turns red. Therefore, the key to managing dry skin is not simply supplying moisture, but repairing the broken barrier and “locking in” the moisture so it does not escape.

For at-home skincare, start by changing the “washing” step

The most common mistake dry-skin patients make is “over-cleansing.” You may think you need to wash until your skin feels squeaky clean to feel refreshed, but this strips away the natural moisturizing film your skin needs.
�
- Use a mildly acidic cleanser: Rather than an alkaline soap or a strong foam cleanser, use a mildly acidic cleanser similar to the skin’s pH to minimize barrier damage. Hot water dissolves the skin’s oils, so lukewarm water is better.
�
- Apply moisturizer within 3 minutes: Right after cleansing, moisture from the skin escapes rapidly. You need to apply moisturizer immediately before the water dries. At this time, I recommend a cream or balm type that contains oil rather than a gel type.
�
- Stop rubbing off dead skin or exfoliating: If you scrub or rub off dead skin because you dislike the white flaking, the already-thinned skin barrier is damaged even more, creating a vicious cycle that worsens dryness.

If home care has limits, you need “direct replenishment” and “regeneration”

Topical cosmetics often stay only on the epidermal layer of the skin. If the tightness deep inside is severe and fine lines are beginning to appear, dermatological treatment may help.
�
- Skin boosters inject a moisture bomb into the dermis: Skin boosters such as Rejuran Healer or water glow injections are treatments that directly inject moisture and nutrients into the dermis, which is like a dry desert. Hyaluronic acid attracts up to 1,000 times its own weight in moisture, quickly relieving inner dryness, and regenerative ingredients help the thinned barrier become thicker and stronger.
�
- LDM changes the skin environment to be more moisturized: For those who are afraid of injections, LDM (Water Drop Lifting) care is a good option. High-density ultrasound energy draws moisture within the skin toward the dermis and stabilizes an unstable skin barrier. Because it helps balance the skin without irritation, it is very suitable for sensitive dry skin.
�
- Laser treatment improves dullness and fine wrinkles: When dryness persists, the skin tone becomes dull and fine wrinkles settle in. In this case, a gentle laser can softly remove old dead skin cells and induce collagen regeneration, creating smooth and radiant skin texture. However, post-laser care is very important for dry skin, so the intensity should be adjusted after consulting a specialist.

If you leave dryness untreated, thinking, “It’s just because it’s winter,” your skin will age rapidly. Just as a dry rice paddy cracks open, skin without moisture is bound to develop deep wrinkles.

Moisture is a measure of health. If you are suffering from tightness deep inside the skin that no cream can fix, visit a dermatologist and check the condition of your skin barrier. We will carefully help your skin become moist and supple again, like a clear spring.
