Why is the skin short of water in autumn and winter?
Water shortage of stratum corneum
The humidity of the air is greatly reduced, and the water in the air is reduced and becomes dry, so that the water in the stratum corneum quickly evaporates. Fast-moving air will take away a lot of moisture in the skin.
Slow metabolism
When the weather turns cold, the speed of metabolism will inevitably slow down, and the blood flow will be slow, which will naturally reduce the moisture brought to the skin surface.
The speed of sebum film formation slows down.
Sebum membrane is what we usually call natural protective membrane. It is a membrane composed of oil secreted by sebaceous glands and partially shed keratin. When the weather gets cold and sebum secretion decreases, it is impossible to form enough sebum film to preserve skin moisture.
What kind of influence can skin lack of water have on the skin?
& gt& gt& gt fine lines breed.
The formation of wrinkles is not only related to the direct decline of skin collagen content, but also closely related to skin dryness. The formation of wrinkles is a process from fine lines to dynamic wrinkles and static wrinkles. Small dry lines, fine lines and wrinkles need to be prepared for a rainy day. Once the skin is dry, we should pay attention to this aging breakthrough at the first time.
& gt& gt& gt skin is very sensitive.
Healthy stratum corneum can retain moisture and has good skin barrier function. On the contrary, when the skin is dry and dehydrated, the space between the cuticles becomes less tight, and the fragile protective layer begins to have loopholes, thus reducing the resistance to the environment. At this time, the skin will change in temperature, external stimuli, and even some cosmetics will begin to show obvious reactions, such as redness, fever, pain, inflammatory reactions and so on.
& gt& gt& gt Dark complexion
Lack of water in cells will slow down blood circulation and increase impurities in the skin, which is not conducive to metabolism. In addition, the stratum corneum that loses moisture will become less soft and the skin will turn gray. If the metabolism of the stratum corneum goes smoothly according to the 28-day cycle and is full of water, then the skin will have a natural luster.
& gt& gt& gt is prone to spots.
There are many kinds of spots, and the mechanism of long spots is also very different. But among many reasons, two factors are closely related to long spots-sun exposure and dry skin. The barrier layer of skin is damaged due to lack of water, and the skin is vulnerable to external invasion, spots and pigmentation; Another important factor is that lack of water leads to the decline of skin metabolism, which weakens the activity of macrophages and cannot "clear" these spots in time.
Replenishing water not only needs to cultivate good living and eating habits, but also needs to be repaired and improved by means of medical beauty in the case of a series of skin problems recurring.
In recent years, laser cosmetology is a very popular non-surgical cosmetology method, which is widely used in medical cosmetology industry.
