Many female celebrities** are particularly delicate, and they rely on insisting on applying ** every day, which replenishes the water. Many people will follow this practice and apply ** every day in the dry winter months in order to make ** moist.
Analyse. **It does have a moisturizing effect, but it should not be applied every day, and some details should be paid attention to when using it at the same time, so as not to hurt the skin care plan**.
Let's talk about it in detail.
Everyone knows that the baby's hair can be broken, and the skin care goals of beauty lovers and the advertising of skin care products are often "having baby-like soft skin". One of the reasons why the baby's cuticle is very thin, and the other reason is that the baby's water content is very high, even up to 40%, and for adults, even if it is a good woman, the water content is often only about 20%.
If the water is lost and not replenished, it will naturally become dry and flaky. In a dry season like winter, it is especially easy to lose water, so it is indeed helpful to do a good job of moisturizing and applying a compress, but you can't apply it often, let's start with your own moisturizing mechanism.
* How to moisturize yourself?
* Like a wall separating the inside of our body from the environment. The "bricks" that make up this wall are small keratinocytes, but the bricks are square, and the keratinocytes are irregular hexagons. Of course, between these "bricks" is not cement, but a variety of lipids, 10 20 such cuticle "walls", which constitute our stratum corneum, which is also our outermost layer. The stratum corneum itself has a very dense structure, and it is difficult for water to evaporate through the stratum corneum, and ** also contains a variety of natural moisturizing factors, which can bind water and reduce water loss.
The stratum corneum will continue to age and peel off with external forces such as our movement and clothing friction, but fortunately, new keratinocytes will continue to grow to fill the gap. In this way, under normal circumstances, our ** can always remain intact and do not give the opportunity for germs and other dirty things to invade.
Why don't you apply it every day?
As mentioned earlier, the high water content makes it look more beautiful, so is it okay to use it every day to hydrate the face?
Under normal circumstances, the water content of the stratum corneum is not high, lower than the average water content of our body, and this also has its physiological significance. We can recall that after swimming and bathing, will our hands and feet be wrinkled due to soaking in water, and they will also become soft?This is the result of the stratum corneum absorbing too much water.
Now some friends apply it every day, and because some of them are higher and don't want to waste it, they put it on for a long time every time, which makes it easy for the stratum corneum of the face to absorb too much water, causing the stratum corneum to become fragile and easy to peel off, affecting the normal barrier function. In order to increase the absorption effect, some friends may exfoliate their faces first, which will have a greater impact. The barrier is damaged, and germs, allergens, etc. may take advantage of the weakness, resulting in redness, swelling, itching and other problems on the face.
Therefore, it is recommended that you apply ** in moderation and do not use it frequently for a long time.
This kind of ** hidden danger is big.
In some cases, glucocorticoids are added in order to "work quickly". This steroid hormone has the effect of regulating sugar, fat and protein biosynthesis and metabolism, and also has significant anti-inflammatory, immunosuppressive, anti-allergic and other effects, and is widely used in clinical practice, but there are various adverse reactions when used in large quantities for a long time.
*The addition of glucocorticoids can inhibit fibroblast proliferation, reduce serotonin formation, and shrink capillaries. Using this "hormone**" can indeed make ** smoother and whiter at first, but if used unmoderated for a long time, it may lead to hormone-dependent dermatitis.
Specifically, glucocorticoids reduce the activity of facial cells, suppress immune cells, and reduce sebum secretion. Once you stop using glucocorticoids**, your face is prone to erythema, scaling, pain, itching, and other problems. In addition, long-term use of topical corticosteroids may also cause atrophy and aggravate infections.
Because of this, the relevant regulations on cosmetics promulgated by the state clearly stipulate that glucocorticoids are prohibited ingredients in cosmetics. Please be sure to keep your eyes open when you buy, don't choose miscellaneous products, special effects are immediate and you haven't heard of the brand.
However, it should be added here that some topical drugs do contain glucocorticoids, which do not need to be rejected, and if there are corresponding conditions, they can be used on time and in accordance with the doctor's instructions. The use of this hormone in cosmetics is prohibited because it does more harm than good to healthy people and is not necessary.
Skincare like this in winter.
In winter** it is easy to dry, and it is feasible to hydrate with **, but it is also necessary to pay attention to the right choice.
First of all, you must correctly judge your ** characteristics, such as dry skin, oily skin, normal skin, combination skin, sensitive skin, etc., and then choose according to your skin type**. The method of judging is not repeated here, you can search the Internet with keywords such as "skin quality judgment score", and it is easy to find the relevant test table as a reference. After understanding your skin type, you can choose the right one.
In addition, we should pay more attention to the use of skin care products containing moisturizing ingredients to reduce the loss of water, and we can also use moisturizing skin care products to lock in moisture after applying.
In addition, in winter, although the sunlight is not as strong as in summer, ultraviolet rays are still enough to cause damage to **, although everyone wears long clothes and trousers in winter, but the face is exposed, so we also need to pay attention to sun protection.
Conclusion. **It can hydrate the skin, but you need to be careful not to use it every day, not for too long each time, especially not until it dries. Choose the right one for your skin type**, and be careful not to choose a suspicious small brand** so as not to buy illegal products with hormones.
