Is your skin moisturized? What you can do to avoid skin problems

If you are suffering from dry skin or irregular texture, your skin may be deficient in water. Keeping the skin moisturized makes it easier to keep the skin moisturized and textured. Here, we will introduce the relationship between skin moisture and skin health, and what you can do to prevent skin problems.

Skin with sufficient water content has gloss and firmness. First of all, let’s take a closer look at how much moisture is ideal for the skin.

The moisture content of the skin is said to be 20 to 30%.

The water content of healthy skin is said to be 20 to 30%. If your skin is shiny and firm and has a smooth texture, it is likely that you are maintaining an appropriate amount of water.

It is dry when it is less than 20 to 30%

When the moisture content of the skin is less than 20 to 30%, dryness, irregular texture, and dry fine wrinkles appear. If the skin is left dry, it may become inflamed by external stimuli and suffer from redness and strong itching.

If you leave skin problems unattended, dullness and age spots may occur, so deal with them as soon as possible.

If your skin is deficient in water, many people think that drinking a lot of water may improve it. Let’s take a closer look at the relationship between water intake and skin water content.

Water alone does not cure dry skin

Drinking water does not always cure dry skin. Dry skin can be caused by a variety of causes, including lack of sleep, nutrition, and lack of exercise. If your skin is dry due to lack of fluid intake, drinking water may help a little.

Drinking water is unlikely to result in healthy skin, as there are often multiple causes.

Get water that is commensurate with your weight

The amount of water you need depends on your weight. An adult weighing 60 kg needs to drink about 2.5 liters of water per day. However, you don’t need to drink 2 liters of water because you can get water from your diet. For example, 1 liter from a meal, 1.2 liters from a drink, and 0.3 liters of water produced by the body can fill 2.5 liters.

The amount of water required per day can be calculated using the following formula.

Weight (kg) x 40

If you weigh 50 kg, 50 kg x 40 = 2,000 ml / day.

A nutritionally balanced diet and skin care are also in parallel

Try to have a nutritionally balanced diet and proper skin care to prevent dryness due to malnutrition or incorrect cleansing. By removing all the causes of dry skin, you can regain the moisture of the skin.

When the amount of water in the skin decreases, the barrier function decreases and skin troubles are more likely to occur. Let’s take a closer look at the relationship between skin barrier function and skin problems.

About barrier function

The outermost stratum corneum of the skin is a very thin layer of about 0.02 mm. There are about 10 layers of stratum corneum cells in the stratum corneum, which are surrounded by a membrane called the cornified envelope. In the stratum corneum cells, there is a natural moisturizing factor called NMF, which retains water.

In addition, intercellular lipids exist to fill the gaps in the stratum corneum cells. A sebaceous film is formed on the outermost side of the skin, preventing the evaporation of water from the stratum corneum.

Four components, Cornified Envelope, NMF, Intercellular Lipids, and Skin Oil Membrane, keep the skin moisturized, and any one of them loses water if a problem occurs.

If the barrier function collapses, it will not be able to retain water.

If the barrier function of the skin is broken, the skin cannot retain moisture and the skin becomes dry. Even if there are no problems with NMF or intercellular lipids, the water content of the skin evaporates when the amount of sebum decreases. Similarly, even if the amount of sebum is sufficient, if there is a problem with NMF or intercellular lipids, it will dry out.

To increase the water content of your skin, you need to review your skin care and lifestyle. By removing the cause of the decrease in skin moisture, it will return to a moderate moisture content. Now, let me show you how to increase the moisture content of your skin.

Moisturizing care

It is important to replenish the skin with lotion. By supporting the water retention capacity of the skin, the lotion leads to moisturized skin. If your skin is deficient in water, you may also be deficient in sebum, so supplement it with a milky lotion or cream.

The order of moisturizing care is lotion, serum, milky lotion, and cream.

Adjust your lifestyle (sleep, diet, exercise)

When sleep deprivation reduces growth hormone secretion, it disrupts the skin turnover cycle and prevents the maintenance of a healthy stratum corneum. Undernourishment due to unbalanced diets and excessive dieting also disrupts the turnover cycle.

In addition, when lack of exercise causes a decrease in muscle mass or a cold body, resulting in poor blood circulation, the supply of nutrients to the skin is reduced and the skin turnover cycle is disturbed.

In this way, sufficient and good sleep, a nutritionally balanced diet, and moderate exercise are essential to maintain the moisture content of the skin.

By adjusting your lifestyle, you can easily balance the amount of water and sebum, and you can expect to improve the barrier function of your skin.

Do not rub too much when washing your face

Rubbing to wash away dirt on the skin can damage the stratum corneum and wash away excess sebum, reducing the amount of water in the skin. If you continue to wash your face incorrectly, your dry skin will never improve.

The point of proper face washing is to wash with plenty of foam as if rolling it on the skin. A foam cushion between your hands and skin allows you to wash away dirt without rubbing your skin.

Be sure to wash with lukewarm water as hot water will wash away excess sebum.
