What is the problem that sometimes you get goose bumps when you are afraid of heat in summer?

Dry: the skin has no climate, and it is more serious in winter!

Skin is divided into epidermis, dermis and subcutaneous fat. The outermost layer of epidermis is stratum corneum. Because of the water absorption and barrier function of the stratum corneum itself, and the natural moisturizing factors such as amino acids, lactate and sugar contained in the stratum corneum, the stratum corneum maintains a certain water content and keeps the skin moist. The appearance of skin is related to the moisture content of stratum corneum. Normal stratum corneum usually contains 10%-30% moisture to maintain skin softness and elasticity. However, with the increase of age, the water content of stratum corneum will gradually decrease. When the water content of stratum corneum is lower than 10%, the skin will be dry, tight, rough and desquamated.

So what are the reasons for skin moisture loss, dry skin and loss of luster? Generally speaking, the internal and external conditions that cause the natural moisturizing structure of the skin to lose balance mainly include:

With the growth of age and skin aging, its moisturizing function and barrier function gradually weaken, and the content of natural moisturizing factors decreases;

● Dry and cold climate with low humidity, such as autumn and winter;

● Some skin diseases, such as psoriasis and ichthyosis;

● Environmental and chemical factors, such as detergents such as washing powder, soap and detergent, organic solvents such as alcohol, and long-term air conditioning environment;

● Eating and sleeping habits, such as partial eclipse, drinking less water, insomnia, etc.

● Dry skin.

Because the skin is in direct contact with the external environment all the time, if it is not protected, it will lack water more or less, which will directly affect the appearance of the skin. At this time, in addition to ensuring a normal and healthy diet, protein and vitamin supplements, trying to avoid the influence of external adverse factors and actively treating skin diseases, appropriate moisturizing cosmetics should also be used as needed.

Seven laws of rejecting drying

In winter, although people like to take hot baths. But the water temperature that is beneficial to the skin is warm water, because hot water will completely wash off the natural oil on the skin, and this natural oil is much more effective than using skin care products to relieve dryness after bathing.

● Generally, bathing in winter should not exceed 15 minutes.

● If you must take a hot bath, use a bath or mild soap as much as possible. After bathing, emollients should be applied to all parts of the body when the skin is not completely dry. Doing so helps the moisturizing ingredients penetrate into the upper layer of the skin.

● When men shave in winter, it is best not to use shaving cream, but to use shampoo instead.

● For those parts of the body that are prone to chapping, it is best to use strong skin care products, such as vaseline. Different from ordinary skin care products, vaseline can "seal" the skin and reduce the evaporation of water, which is very effective in protecting dry skin.

● Use some hand cream that can keep moisture after washing or washing hands.

● At home, there are more exposed places than outdoors. Using humidifier is a good way to solve dry skin.

There are many skin problems in winter.

Skin itches easily, chapped hands and feet, and frostbite will come to you.

When the northwest wind blows, people's skin will be greatly reduced because of the drop in temperature. Whether it is overt sweating or covert sweating, the secretion of sebaceous glands, the lubricant of human skin, will also be greatly reduced. Except for babies, most people's skin will be dry. At this time, some common skin diseases in winter began to wreak havoc in some people. Many people, especially the elderly, complain that the skin is itchy, dry, scaly and itchy. Going to the hospital for dermatological treatment is often diagnosed as winter itching or seborrheic eczema.

So, why are some people's skin particularly dry in winter? Dry skin is related to skin dehydration, and insufficient skin moisture is related to skin's natural sebum. The lipid on the skin surface is like a coat, which prevents the skin from evaporation and keeps the skin moist. The skin of the elderly is thinner, and the lipid on the surface is also reduced, so the skin naturally appears dry. The cold wind in winter will increase the loss of water and further disturb the lipid balance of epidermis, so drying is inevitable.

Itching skin: dry skin is the culprit.

Primary skin pruritus is undoubtedly the most common skin disease in winter, which can occur in men, women and children, but it is more common in middle-aged and elderly people, especially the elderly. The patient will itch all over. During the day, due to external interference, they will be distracted and have no time to care about it. At night, the itching is unbearable, and the ants seem to climb all over the body, which is unbearable. If you eat some "hair", or drink wine and coffee, it will itch more. However, when examining the skin, there is no primary rash, only secondary damage such as scratches, scabs or pigmentation caused by scratching can be seen. If it lasts for a long time, tinea versicolor can be secondary.

This disease is mainly caused by dry skin. In winter, when we take off our cotton-padded sweaters and trousers, we can often see a lot of tiny dander bouncing off our bodies. In winter, we wear many tight clothes, so that foreign bodies irritate sensitive skin and itching is inevitable. There is also that some people will aggravate itching if they do not handle it properly. For example, hot water washing can temporarily relieve itching, but it will make it more serious. Because hot water is a kind of stimulation to the skin itself, and sebum is removed more, resulting in drier skin.

The key to skin itching in winter is that the skin is dry and cold, so it is necessary to maintain a certain humidity indoors. You can put some green potted plants or put a basin of water to increase the air humidity. When taking a bath, the water temperature is about 32℃, so it is not suitable to rub and wash. Too much soap is used to avoid scratches. After bathing, you can apply moisturizing lotion all over your body to keep your skin moist. It is recommended to apply moisturizing cream or moisturizing lotion every day. If necessary, you can also take the first generation of anti-allergic tablets orally to achieve the effect of relieving itching and calming down. Try to eat more foods rich in vitamin A, such as carrots and cabbage, and eat less coffee, cola and hot and sour food.
