Description

Gel type cosmetic composition for using skin keratin removing and manufacturing method

The present invention relates to a cosmetic composition for exfoliating skin in the form of a gel, and a method for preparing the same. More specifically, the present invention relates to a cosmetic composition for exfoliating skin in the form of a gel which can effectively remove unnecessary keratin on the surface of the skin which causes skin dullness without irritation, and a manufacturing method thereof.

It is the constant desire of all women to have fine skin. Fine skin refers to glossy, clear and elastic skin. It is well known that human skin undergoes a series of processes in which the skin loses its elasticity and luster as aging progresses, and it becomes fine and fine wrinkles, and eventually skin aging progresses.

Keratin covers the skin of our body, and serves to prevent the evaporation of moisture in the skin and the ingress of foreign substances from the outside. However, when too much of this keratin is accumulated, the skin texture becomes rough and the skin tone becomes cloudy. In addition, it interferes with the skin's ability to receive nutrients. Especially in autumn and winter, the skin is dry, so the skin becomes rougher, dead skin cells thicken and split.

Therefore, in order to remove the dead skin, using a commercially available scrub (scrub) product requires careful care to remove unnecessary dead skin of the skin regularly once or twice a week. Especially in cold winters, the indoor life is increased, and the room becomes dry due to heating, which deprives the skin of moisture, which can cause the skin to feel dry, which can lead to itching of the skin. It may also occur. In this case, it is necessary to manage keratin because harmful bacteria may invade the gap and cause skin diseases.

The corneum is a derivative of the Latin cornu, meaning hard as horns, representing the hardening of the cells that reach the surface of the skin.

Common expressions are the top layer, uppermost layer, outermost layer and Latin, meaning the outermost or upper layers of the epidermis, such as the Horny layer and the horn. There is a hard or stratum corneum, also called the cellular upper layer (cellular upper layer) of the cell layer. The cells that reach the stratum corneum express hardened keratinization. The cells that reach the stratum corneum are keratins, which are flat dead cells, where millions of dead keratinocytes are removed from the skin and replaced with new ones. When the cells of the basal layer filled with 70% moisture reach the stratum corneum, the moisture is reduced to 20%, turning into keratinocytes. The stratum corneum, which contains about 20% moisture, is the condition that maintains the best condition of the skin. When the skin's moisture drops below 15%, it becomes dry, cracked, and rough. The glue that keeps the cells from sticking together is called a substance called intercellular cement. The cement-bonded cells do not fall off quickly as they age, and the circulation of keratinocytes does not occur, making the skin dull and rough, and aging faster, causing wrinkles and rough skin.

The keratinocytes produced in the basal layer come up to the granules in 14 days. Kerathyalin is initiated by the action of keratohyalin in the granular layer. The body fluids in the cells have already escaped and the cells are flattened, ready for keratinization. The nucleus, cytoplasm and organelles of the cell degenerate and are replaced by keratin-hyline and then converted back to eleidin and then to the last stage, keratin, ending the life of the cell and pushing up to the stratum corneum. Keratin is a sulfur-containing protein. Skin is soft keratin with 20% moisture. Hair and nails are hard keratin without moisture.

Exfoliating the skin can be divided into chemical and physical methods. Chemically, it is a method of decomposing and removing the desomosome existing between keratinocytes by appropriately acting moisture and temperature like proteolytic enzymes and using organic acids such as alpha-hydroxy acid and beta-hydroxy acid. There is a way.

However, if this keratinization process is not smooth, abnormal keratinocytes are produced, and the surface of the skin is thickened, the stratum corneum is thickened, the skin is roughened, the skin becomes dull and the makeup is rendered poorly or does not look good. Therefore, women are trying to overcome this phenomenon, and cosmetics companies are launching various cosmetic products using exfoliation and moisturizing of dead skin cells to relieve dull skin.

Therefore, the present inventors have developed a cosmetic that can minimize the skin irritation while compensating for the disadvantages of the conventional exfoliant and allowing the scrub to be automatically generated and extinguished by friction of hands and skin during massage, thereby minimizing skin irritation. To complete.
