Skin hydration in Daegu: water content, the skin barrier and water loss
Read the Korean original
Summary It explains the relationship between the moisture contained in the skin, the moisture that escapes from the skin, and the skin barrier that regulates this.
Key information
Hydration involves retaining water as well as adding it. Skin water content and transepidermal water loss are different measures; dryness, irritation and barrier condition should be assessed together.
Before your consultation
- How the stratum corneum retains water
- Water content and transepidermal water loss
- Dryness in oily skin
General information, not a personal diagnosis or treatment plan. Suitability, risks and recovery require an individual consultation.
How the stratum corneum retains water
The stratum corneum, the outermost skin layer, forms a barrier through its cells and surrounding lipids. Removing large amounts of dead skin simply because the skin feels dry may strain this protective function. A temporarily smoother surface and a stable skin barrier should be assessed separately.

Water content and transepidermal water loss
Water content describes the amount of water in the skin, and transepidermal water loss describes the water that escapes through the skin. One indicator does not replace the other. If conditions such as face washing, cosmetics, and indoor environment are not met before measurement, there will be limitations in comparing values from different days.

Dryness in oily skin
Shininess is associated with oil on the skin's surface, while tightness or stinging may reflect other problems. Do not repeat strong cleansing or exfoliation just because it is oily. You should check the face wash, acne treatment, and recent procedures you use to narrow down the cause of your dryness.
Moisturizers versus injectable treatments
Applying moisturizers deal with maintaining moisture on the skin's surface and providing a feeling of use, while injection procedures have separate purposes and risks for each product and method. Injections do not solve the problem of lack of daily moisturizing in all cases. It is better to divide the goal into relieving dryness and changing skin structure and have each role explained.
Reducing irritation and recording changes
When you change multiple new products at the same time, it's hard to tell which changes are helpful. Take note of any tightness after washing your face, any stinging throughout the day, and any visible redness. Severe pain or persistent inflammation should not be treated as simple dryness, but should be checked by a doctor to determine the cause.

Daily conditions to discuss at a Daegu consultation
If you work in an air-conditioned environment for long periods of time in downtown Daegu, please include the number of times you wash your face, the indoor environment, and your current cosmetics. When comparing Dongseong-ro's official skin care/skin booster menu, it is better to check whether the plan fits your symptoms and living conditions rather than just the moisture measurement alone.

FAQ
What role does the skin barrier play in moisturizing?
The stratum corneum, the outermost skin layer, forms a barrier through its cells and surrounding lipids. Removing large amounts of dead skin simply because the skin feels dry may strain this protective function. A temporarily smoother surface and a stable skin barrier should be assessed separately.
Can oily skin also become dry?
Shininess is associated with oil on the skin's surface, while tightness or stinging may reflect other problems. Do not repeat strong cleansing or exfoliation just because it is oily. You should check the face wash, acne treatment, and recent procedures you use to narrow down the cause of your dryness.
How do I record changes in moisturizing care?
When you change multiple new products at the same time, it's hard to tell which changes are helpful. Take note of any tightness after washing your face, any stinging throughout the day, and any visible redness. Severe pain or persistent inflammation should not be treated as simple dryness, but should be checked by a doctor to determine the cause.
