The goal of cosmetics is to maintain beautiful and healthy skin, and also to delay the aging of naturally occurring skin as it gets older. In general, aging is caused by oxidative damage of biomaterials by free radicals. That is, reactive radicals such as active oxygen such as hydrogen peroxide, hydroxy radical, and superoxide radical peroxidize the lipid constituting the cell membrane to destroy the cell membrane, oxidize the protein, attack the nucleic acid and cause oxidative damage, Destroys and eventually kills cells. Skin characteristics that are most noticeable due to aging include wrinkles, decreased elasticity, and skin dullness. In addition to wrinkles and elasticity decline, after 40s, facial color is not clear and is often gray and dark. Especially for young women, when they experience childbirth, they have eosinophilia, blood circulation disorder, which causes their metabolic ability to fall and their skin to become rough and rough. When the metabolism ability is lowered and the skin becomes rough, the water content is also easily reduced. Generally, the moisture content of the skin is about 70% in the dermal layer, but decreases to the skin layer to about 10 to 30% in the keratin layer. The keratinocyte layer is known to have an important role in the moisturization of the skin due to the existence of a substance having a hydrophilic water retention capacity called a natural moisturizing factor (NMF). Normal keratinocyte layer maintains skin smoothness and softness and maintains normal body protection function when moisture is maintained at about 10 to 30%.

Therefore, proper maintenance of the moisture content of the keratinocyte layer is very important for preventing skin aging. However, other natural moisturizing factors such as sodium pyrrolidonecarboxylate (PCA-Na), sodium lactate, There is a problem that the emulsion stability of the cosmetic is impaired due to the strong electrolyte. Amino acids, collagen, elastin, etc. are also capable of moisturizing, but also had a limited ability to moisturize. The ability of the horny layer to retain moisture can be controlled by natural moisturizing factor (NMF), which consists of sebum components, amino acids, lactic acid, urea, and inorganic salts. And the development of a substance with high moisturizing effect is one of the important research subjects in cosmetics. Materials known to have antioxidant activity include ascorbic acid, dl-alpha-tocopherol, beta-carotene, dibutylhydroxyltoluene (BHT), and the like. Since the materials are used as a synthetic material, there is an urgent need to develop new antioxidative cosmetics which can be applied to skin safely and usefully, because they may cause problems of skin safety when used for a long time or in a large amount.

Therefore, studies on skin aging and moisturizing improvement are expected to be continuously carried out. Many cosmetic products using natural products are being developed in order to solve such skin problems and to reduce skin irritation caused by various chemicals. Natural materials are not only less harmful to the skin, but also have increased their value as a raw material for cosmetics due to the recent popularity of cosmetics using natural materials.

For this purpose, researches are being actively carried out to develop materials having excellent safety and skin beauty effect by searching skin physiological activity of various natural vegetable persons.

One of the natural materials, sea cucumber is a generic term for sea cucumbers belonging to the sea cucumber river of the dyke. It was named for its efficacy as ginseng. In the "Mizobo" and "Oozoku", there are "Hainan", "Munsun", and "Sukkyeon" Sea cucumbers "," sea cucumbers "," sea cucumbers "and" black cucumbers "are recorded in the" sea cucumbers ". In Japan, it is called nama-ko which means "sea turtle" because it is nocturnal and resembles a mouse. In Gyeongbuk Province, it is also called red ginseng.

The body of the sea cucumber is cylindrical, the abdomen is flat, the back is convex, but there is also no distinction between the back and the abdomen. The mouth at the tip of the body has 10 to 30 tapered tentacles. The tentacles absorb the nutrients by sucking the mangoes of the sea floor, and the rest are excreted outside the body. It is made of mucus and is slippery. There are a lot of calcareous small fragments in the skin, and it is used as a trait of the sea cucumber in the shape of a bone fragment. The body wall is thick with muscle and connective tissue. There are digestive tracts, cysts, blood vessels, nerves, reproductive organs in the body, crawling or swinging in the body and only a few species float in the deep sea. In the skin there are small fragments of calcareous bone fragments. There is a distinction between male and female, but it is difficult to distinguish by appearance. When the water temperature is 17 ℃ or less, the appetite is active and the exercise is active. When it is above 17 ℃, it stops eating, and when it is 25 ℃ or more, it sleeps in the summer. When you eat food, tentacles put sandy mud under the sea in your mouth, eat small creatures in sandy mud, eat sand and excrement out. When stimulated from the outside, the intestines are cut off and sent out of the anus, which is regenerated and regenerated. There are about 1,500 kinds of sea cucumbers in the world, and there are three kinds of sea cucumbers produced in Korea: red ginseng, red ginseng and black ginseng.

Sea cucumbers are the best ginseng preparations, and they were used as a tackifier in the oriental herbal medicine. It is because the sea cucumbers reduce the heat of the body while the blood is being blood-drawn (blood), and the kidney of Hako, who controls the excretory organs, is benefited to strengthen the tincture. Animals that sleep in the hibernation or the lower part of a horse for a certain period say it is good for the energetic. Also, for women, it is often a good food to complement the body during pregnancy, when a weak woman or placenta wears a sea cucumber instead of a ginseng to a pregnant woman who is weak.

The main active ingredients of red sea ginseng are chondroitin sulfate, terpenoide, glycoprotein, taurine and calcium.

Especially, triterpenoid glycoside derivatives have various effects on the skin. Asiaticoside, a pentacyclic triterpenoid glycoside, has antibacterial and antifungal properties, and has wound, gastric ulcer, It has been investigated that various skin diseases, mental diseases, tuberculosis, vein diseases and dementia have therapeutic effect. Recently, it has been reported that asiaticoside-derived derivatives protect cells from β-amyloid-induced cell death. Thus, triterpenoid glycoside derivatives are used in various applications such as edible, skin treatment, wound treatment, memory enhancer and tonic, and they are also used in the fields of medicine, cosmetics, functional foods, etc. (Immuno-Regulatory Effect on Centella asiatica L. Urban Extraction Solvent Associated with Ultrasonification Process. Korean J. Medicinal Crop Sci . 16 (5): 294 300 (2008).

In addition, many research reports have been made on triterpenoid saponins and ginsenosides. Among them, ginsenoside Rb1 is effective against gastritis and gastric ulcer and has antioxidant activity. Ginsenoside Rb2 has an antagonistic action against cancer toxin hormone and inhibits tumor angiogenesis. Ginsenoside Rc is a metabolite of intestinal bacteria The possibility of developing an anticancer drug has been reported. Ginsenoside Rd has been reported to have a therapeutic effect of nephrotoxicity and to protect the nervous system (ginsenoside content analysis of ginseng, goat ginseng and wild ginseng, and observation of changes after red ginseng). March).

However, triterpenoid glycosides are contained in trace amounts in sea cucumbers, which is not economical when used industrially.
