What is keratin? What does it look like? What is?

You will know with a pinch of exfoliating cream, if your **roughness is still recommended to buy a suitable exfoliation cream, the keratin will not go for a long time, it will affect the health.

The stratum corneum (jiaozhiceng) is a layer of fatty material on the surface of the aboveground organs (such as stems, leaves, etc.) of plants. It is secreted by epidermal cells. It is most pronounced on the surface of the leaves; The outer layers of the epidermis of twigs, flowers, fruits, and young roots also often have this structure.

Its function is mainly to play a protective role, it can not only limit the loss of water in the plant, but also resist various adverse effects such as microbial invasion.

corneum）

Consists of 5 to 10 layers of deceased flat keratinocytes, the nucleus and organelles of which have completely disappeared. Under the electron microscope, the stratum corneum cells are filled with dense parallel keratin tension filaments and are immersed in amorphous substances, mainly histidine-rich proteins contained in hyaline keratin. The inner surface of the cell membrane is attached with a layer of insoluble protein about 12 nm thick, so the cell membrane is thickened and strong.

The surface of the cell membrane is wrinkled, the cells are chimeric with each other, and the intercellular space is filled with lipids released by keratinosome granules. Desmosomes are still visible between the stratum corneum cells near the transparent layer, while the desmosomes of the cells on the surface of the stratum corneum disappear and are prone to peeling off to form flakes.

The important chemical component that makes up the stratum corneum is keratin, which is a hydroxy fatty acid containing 16 to 18 carbons. The stratum corneum is often divided into two layers, close to the outer wall of epidermal cells, and is a keratinized layer composed of keratin and cellulose; Outside the cell wall is a thin layer of cuticle, made up of keratin or mixed with wax. The thickness of the cuticle is greatly affected by the environment, and the leaves grown under drought and sunny conditions have a thicker cuticle and more wax. Growing in water or in a damp environment is thinner or even non-existent.

1. Keratin is a hydroxy fatty acid containing 16-18 carbons. It is a horn-like texture, similar to a cow's horn or antelope horn, and is generally solid and translucent. Keratin is the main component of the stratum corneum.

2. **Divided into epidermis, dermis, and subcutaneous tissue; The surface layer is divided into five layers, from bottom to top are the basal layer, the spinous cell layer, the granular layer, the transparent layer, and the stratum corneum.

3. Cells start to grow from the basal layer, with the passage out, through the process of aging and death, keratin is the last product of the continuous regeneration of epidermal cells, **surface stratum corneum is thick, **will lose luster, gray, peeling, wrinkles, acne, etc. The cycle of keratin formation is about a month, so beauty experts pay attention to 28 days to remove stuffy keratin.

4. Hair, nails, and cuticles on the surface of ** are keratin. Keratin is a layer of tissue in the epidermis of some animals and plants, with a tough texture, composed of chitin, limestone, etc., which has the effect of protecting internal tissues.

Keratin is the main component of the plant stratum corneum, is the first natural barrier of the human body, the aging and shedding of the stratum corneum is the normal metabolism of cells, the existence of the stratum corneum also has a certain resistance ability, for light absorption, the human stratum corneum is relatively thin, so the stratum corneum can not be removed frequently.

Keratin is the main component of the stratum corneum of the plant, and it is also a wall to protect the first place, the stratum corneum is the outermost layer of our **, the aging and shedding of the stratum corneum is the normal metabolism of the cells, but if there is no good maintenance of the stratum corneum in daily life or with age, the aging keratinocytes will not fall off.

Horn is similar to the texture of horns, similar to bull horns, antelope horns, and generally has a firm texture and is translucent. The stratum corneum is the first natural barrier of our human body, which has a certain impedance ability to low-voltage currents, and at the same time has the ability to absorb light, and has a protective effect against chemical damage.

The stratum corneum of the human body is generally relatively thin, so it is not possible to remove the stratum corneum through the trousers every day, otherwise the skin will become sensitive. It takes about 28 days for the human body's natural metabolism, and related products can be used every other month to exfoliate, which can help the old dead keratin fall off and make the ** diotanan smooth and elastic.

Keratin refers to the gradual aging of cells in the epidermis. The epidermal cells of keratin are actually the first to gradually age, and eventually gradually shrink, and the nucleus gradually disappears, and finally forms a keratinized state of cell residue. Usually these keratin cells are distributed outside the epidermal cells, on top of the granular layer cells, and this substance usually appears as a grayish-white texture with a relatively hard state.

It has a certain protective and barrier effect on **, and also has a certain role in retaining moisture.

It's going to be exfoliated. Avoid enlarged pores** dryness. It is necessary to pay attention to eliminating the dead cuticle on the surface of the **, and it is still necessary to remove the keratin on the face regularly.

But there are some** that do not need to be exfoliated, such as having a good cleaning habit every day, especially those with red blood capillaries**, never exfoliate.
