Basically, all dermatologists will tell you that the most basic skin care is to clean up, moisturize, sunscreen isolation, moisturizing as one of the three key skin care stages, in the dry autumn, it is vital.

How do you want your skin to be moisturized to be more reasonable? The first thing you need to understand about skin moisturizing is what exactly is moisturizing?

The most important thing that you can do is to make sure that you have a good idea of what you are doing. The stratum corneum, despite being a layer of dead cells, is an essential key player in the skin moisturizing process.

The stratum corneum has a maintenance effect on the skin, it helps save the skin from moisture drainage on the one hand, and blocks external germs and dirt on the other, helping to keep the skin physically and mentally healthy.

What is meant by the stratum corneum?

The epidermis can be divided into stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum and stratum dermis from top to bottom.

When the keratinocytes reach the most superficial layer, this cytobridge feels dissolved by proteolytic enzymes, and all normal conditions, the keratin will fall off together with the basic metabolism over the years, and the cells located in the dermis underneath will be pushed up to produce a new keratin layer to maintain the excellent moisturizing actual effect of the outer skin.

The whole process of shedding is very critical, if skin care is not reasonable, keratinocytes are shed too early, newborn keratinocytes can not catch up to transform into, will cause the natural barrier role of the stratum corneum to reduce, very easy to suffer external irritation skin allergies.

In turn, to the time of shedding does not fall off, brittle keratinocytes adhering to the stratum corneum, the skin will cause white flakes, resulting in rough, brittle, and even cracked skin.

The enzyme "keratinolytic enzyme" is responsible for the shedding of keratinocytes, and this enzyme must be specific to the standard of abundant moisture to be effective. If there is a lack of water, all the normal upgrading of the stratum corneum is not carried out, and many unshed stratum corneum cells remain on the surface of the skin.

This is one of the reasons why the skin is dry, white flaky and not smooth after less water. The necessity of moisturizing becomes obvious with how crucial moisture is for the stratum corneum.

How does the stratum corneum moisturize the skin?

The stratum corneum contains many water-locking chemicals, which are divided into two key categories: the pure natural lipids between the stratum corneum and the moisturizing factors, which are added to the middle of the stratum corneum cells.

The stratum corneum is composed of 10-30 layers of keratinocytes and intercellular lipids. The cells of the stratum corneum carry a lot of water, which is absorbed by the natural moisturizing factor (NMF) in the keratinocytes and provides the basic metabolic application of the keratinocytes.

If there is a lack of water, the natural moisturizing factor has no water "can guarantee", all the normal metabolism of the keratinocytes occur problems, all the normal physiological role is endangered, will cause a series of skin problems.

If the keratinocytes are moist and round, sorted, the smoothness of the skin will be very good. If the water outflow, keratinocytes gradually close, cell space expansion, skin barrier role is reduced, it is very easy to suffer external irritation, resulting in skin allergies, swelling, itching, stinging and other discomfort disease.

Water is the root of all physiological theme activities of keratinocytes, less this root, keratinocytes many physiological efficacy is will suffer harm.

It can be said that the moisturizing and hydrating skin care products are all made after the ingredients of the keratinocytes. The natural lipids metabolized by keratinocytes and the natural moisturizing factors are the key moisturizing ingredients, which are also the common ingredients in skin care products.

"Natural lipids" include ceramides, squalane, oleic acid, carbohydrates, glycerides, and other ingredients. The "natural moisturizing factors" include a wide variety of hyaluronic acid, carbohydrates, acid salts, glycans, lactic acid bacteria, PCA, glycans, chloride, sodium, calcium, magnesium and other positive ions and their urea solutions.
