Cold season, many people because of the fear of cold and actively reduce the frequency of bathing, from the summer of a daily wash, to 3 days a time, or even a weekly wash. And because of the long interval between baths, each time you feel a lot of dirt on the body, to scrub vigorously to clean. Another part of the people feel that, in addition to rubbing off the dirt, but also can rub off the dead skin, to the skin to exfoliate, help skin beauty, should be rubbed every day, the truth in the end how is it? What does scrubbing remove? Dirt needless to say, keratin can also rub off a lot. But keratinocytes from the newborn to shedding needs 28 days, too frequent exfoliation, skin compensation is not as good as, in fact, is harmful. The stratum corneum is the first line of defense of the skin surface, in addition to resisting foreign microorganisms, mechanical, physical and chemical stimuli, but also to prevent the loss of water percutaneous too fast; if the stratum corneum is all lost, the water lost through the skin osmosis will be at least 10 times faster. Therefore, frequent rubbing, in fact, rubbing off an important physiological line of defense of our skin, in some of the original history of skin allergies in the population, which often leads to an increase in the incidence of allergies. In addition, rubbing vigorously will also rub off the skin surface only a little sebum layer. The climate in most parts of the country is influenced by the monsoon, which makes winters relatively dry. When the external humidity decreases, the degree of hydration of the stratum corneum on the surface of our skin will also follow the decline in sebum secretion decreases, the skin is prone to dry and flaky situation. If this time excessive cleaning, vigorously scrubbing, will be relatively thin sebum layer completely rubbed off, exacerbate skin dryness, and even induce pruritus and a series of dry skin lesions. Winter scrubbing is good or bad? The metabolism of keratin is all the time, spring and summer wet season sebum secretion, high degree of hydration of the stratum corneum, it is less off, the naked eye is not easy to observe; fall and winter, it is easy to find the skin surface and even close to the clothes have obvious flaking, this “chip” that is, the shedding of keratinocytes. Therefore, there is no need to worry too much about exfoliation in the winter: it is already easier to fall off than in the spring and summer. You don’t have to exfoliate if you want your skin to be smooth and moisturized. Excessive exfoliation can also lead to faster evaporation of moisture through the skin, which is the key to softening it during the dry season of fall and winter. But it is essential to worry about moisturizing in the winter. In order to protect the cold wind in the last point of our weak poor sebum layer, winter bath time may wish to pay attention to the following points: 1, the bath is not only should not intentionally rubbing vigorously, even the bath water should not be too hot. 2, bath time should not be too long, the number of baths can be reduced to two or three days about a wash. 3, after the bath should also be applied to a large area containing Vitamin E, urea and other ingredients of the skin cream, to achieve moisturizing and softening keratin purpose, so that the skin is tender. Under what circumstances can I rub? Keratosis pilaris is a very common chronic follicular keratosis pilaris, which is commonly known as “chicken skin”, which I believe you have heard of if you haven’t had it. It occurs in young people on the outside of the arms, legs and other parts of the anterior side of the manifestation of the pinpoint size of the small pimples, pimples in the middle of a hard keratinous plug, remove the keratinous plugs can be seen inside the small Cui hairs. Usually not painful and not very itchy, is not very good looking. Winter is more serious than summer. There are a lot of “cure chicken skin” recipes on the Internet, but in fact, keratosis pilaris is a self-limiting disease, that is to say, even if you do not go to the treatment at all, it will gradually subside on its own, only very slow. There are no remedies to cure it before it goes away. If you think “chicken skin” is ugly and can’t stand it for a moment, the most practical way is to use a slightly hard scrubbing tool like a loofah in the shower and gently rub the area, which can improve the situation. 1, frequency can be adjusted according to their own situation, generally appropriate once a week; 2, each time not too hard, to the skin slightly red without pain is appropriate; 3, can only be rubbed locally, do not rub the whole body; 4, after the bath need to use 10 ~ 20% of the urea ointment or ointment of cod liver oil, softening keratin, moisturizing care; 5, need to adhere to a number of years until it heals itself.
