Skin care 5 asks, water shortage is really older than ultraviolet light

True! The normal skin's stratum corneum moisture content is between 20% and 30%. When the skin moisture content is lower than the daily stable value, it will feel tight and the skin will become rough. Once the water content of the stratum corneum is less than 10%, it will directly affect the normal metabolic function of the skin, and the external harmful substances are also more likely to enter, causing skin irritation.

2. I obviously drink a lot of water every day, how can I still do it?

Drinking water is the basis of skin hydration, not all. Although most of the skin's water is supplied by the body, drinking enough water is the basis for ensuring the healthy moisture content of the skin. However, how to obtain and combine more moisture in the skin while preventing excessive loss of water is related to the moisturizing mechanism of the skin itself. This part needs skin care products to improve.

3. What factors cause skin water shortage?

Even if the skin is dry, if it is maintained within a stable moisture value, there will be no major skin problems. The real lack of water in the skin often comes from outside influences. For example, exposure causes a lot of water loss, and ultraviolet rays can damage the skin barrier. Fever, lack of sleep, stress, nervousness, the body automatically enters the "dehydration mode." Excessive drinking and heavy eating will also consume a lot of water in the body, resulting in insufficient skin supply.

4, I often spray spray, open a humidifier, take a lot of lotion on the face, useful?

A little help, but not comprehensive. The humidifier raises the humidity of the environment. The spray and lotion just make the stratum corneum full of water for a short time. It looks good, but it doesn't last long. Replenishing water, in addition to replenishing moisture, is more important to protect and restore the skin's ability to acquire and store water.

5. If the hydration is not done well, will it hinder the absorption of the follow-up skin care products?

The skin that does not interfere with it, but the water is filled, is more beneficial to the active skin care products. When the skin is excessively dry and damaged, the internal moisture and minerals are largely lost, and the external matter is partially in good or bad, causing irritation. In the case of damage, most skin care actives do not normally stay in the skin to play their due role.
