The pores are holes that grow hair. Except the palms, soles, and lips, they are present in the whole body skin, and they are mainly distributed on the face, neck and chest. The sebaceous glands attached to the pores secrete sebum, which protects the skin from the outside, prevents bacterial infections, and moisturizes the skin.

The sebaceous glands are not active before adolescence but become pubescent, and if the sex hormones are secreted vigorously from the body, the sebaceous glands become larger and produce more sebum and discharge them out of the pores, resulting in diseases such as acne. The function is deteriorated and the skin is easily dried, causing itching and the like.

Therefore, the size of the pores during puberty can be enlarged, and when sebum is excessively produced, the sebum remains in the pores during the discharge of the sebum from the pores, and the pores can be further expanded.

Other causes of skin pore enlargement include aging of the skin, collagen and elastin, which inhibit the activity of keratinocyte and dermal fibroblast and support the pores. elastin, and water retention ability, thereby reducing the elasticity of the skin, thereby causing the pores to expand. In addition, the pores can be expanded by various extrinsic and endogenous factors such as season, genetics, sex, and excessive secretion of sebum.

The pores are normally present in the skin and do not pose a problem in itself. However, if the pores are enlarged and visually seen, it may become a cosmetic problem, and excess sebum may be excessively discharged to adversely affect skin health .

Hereinafter, embodiments of the present invention will be described in detail, but it should be apparent that the present invention is not limited by the following examples.

One aspect of the present invention relates to a desalted lava waters; And a cosmetic composition comprising a volcanic stone clay, a persimmon leaf extract, a mandarin orange peel extract, and a Sasa extract as an active ingredient.

The above-mentioned "Lava Seawater" is an underground seawater flowing into the ground under natural filtration of seawater through a permeable volcanic rock layer. It is mainly buried in the eastern part of Jeju. It flows up to 8 km from the coast and flows through the volcanic rock layer . The lava seawater is not mixed with each other due to the difference in density with freshwater groundwater, and exists below the freshwater layer.

Since the 1980s, Jeju has been used as a breeding ground for flounder farms by utilizing characteristics such as low temperature and cleanliness of lava seawater, and it has been widely spotlighted as being used as water for sauna and the like in terms of health and beauty. Lava seawater, which is distributed only in the eastern part of Jeju Island (Gucheong-eup, Seongsan-eup, and Seokseon-myeon), is clean and has a constant water temperature throughout the year. It contains a large amount of various minerals not found in ordinary salt water or seawater. It is not described in detail in this document, but has already been known in the existing documents (Patent No. 10-1402025 et al.). In particular, vanadium contained in trace amounts in lava seawater has been known to stabilize insulin secretion, and germanium has an effect on blood circulation promotion, immunity enhancement, anti-cancer effect, etc. Selenium inhibits oxidation of fat, Anti-cancer, infertility, suppression of aging, and improvement of cholesterol levels.

The lava seawater not only possesses abundant minerals but also inhibits the activity of 5α-reductase, has excellent acne improvement activity, exhibits degranulation inhibitory activity (β-hexosaminidase free inhibitory activity), and antihistamine And exhibits activity of promoting the production of type I collagen when treated with fibroblasts.

The lava seawater is very clean because it is naturally purified during the passage through the basaltic layer, and unlike deep sea water, which is taken from the deep sea, it is cost effective because it can be taken from the land.

The &quot; desalted lava water &quot; is a result obtained by desalting lava seawater, and may be a partially dehydrated (with some water removed) concentrated liquid phase or a completely dehydrated powder phase. The phase of the desalted lava waters is not particularly limited, and a composition containing minerals may suffice.

The desalted lava waters may be obtained by applying any technique known in the art and may include but are not limited to flash evaporation method, seawater freezing method, reverse osmosis method, ion exchange resin method, electrodialysis method, Can be appropriately selected in consideration of the characteristics. Specifically, the reverse osmosis method uses a reverse osmosis membrane to remove salt, and the electrodialysis method selectively lowers the concentration of sodium without changing the concentration of the required mineral selectively.

According to one embodiment, the complex extract may be composed of a volcanic stone cluster, a persimmon leaf extract, a mandarin orange peel extract, and a sour extract. The complex extract may have an excellent skin improving effect due to the synergistic action of the active ingredient derived from each plant raw material. In particular, the complex extract is applied to the skin along with the rich minerals contained in the desalted lava sea water, thereby increasing the absorption rate and maximizing the skin improvement effect.

The "volcanic stone pine" is a mixture of volcanic rocks, volcanic sand, and other volcanic ash that was erupted when the volcano erupted, and the magma was fired by high temperature and released into the atmospheric layer. Volatile components in the volcanic rock escaped, It refers to the embankment. The volcanic stone clusters are formed into a porous structure including numerous fine holes in the course of high-temperature gas and lava being ejected first, so that they can have excellent adsorption and sterilization power. In addition, since the volcanic stone cluster contains a weakly alkaline natural mineral component, it emits a large amount of far-infrared rays and is excellent in blood circulation promotion, metabolism promotion, cell function activation, growth promotion action, water molecule activation and aging effect.

The "persimmon" is a deciduous broad-leaved arboreous tree belonging to the persimmon family, among which persimmon leaves are rich in vitamin C. The tannin component contained in the persimmon leaves has a bland flavor, and is effective in various biological activities, as well as in detoxifying toxins and increasing immunity. The leaves of the persimmon may be selected from the group consisting of astragalin, myricitrin, flavonoid glycosides, polyphenols, coumarin compounds, betulic acid, oleanolic acid, Urosolic acid, chlorophyll, vitamins A and C as well as various water-soluble and lipophilic bioactive substances such as vitamin B1, pantothenic acid, and folic acid.

On the other hand, the above-mentioned &quot; mandarin &quot; is rich in vitamin C and citric acid, and contains vitamin P, phosphorus, and hesperidin excellent in capillary strengthening action. The active ingredient is contained in the skin more than flesh, especially about 4 times as much as vitamin C. The orange extract has an excellent effect of neutralizing IL-8, an inflammatory substance that stimulates melanocyte stimulation by stimulating melanocyte, and neutralizes melanocyte-stimulating substances, thereby inhibiting melanin production, thereby creating a radically healthy and clean skin .

In addition, the above-mentioned "Hashuo" is known to originate in China and is a vine medicinal plant that has been cultivated for a long time. Its height reaches 3 to 4 meters and its roots stretch sideways to form roots. It is widely known as a medicinal herb that has reddish-brown roots and is called "Sasuo". It strengthens the kidneys and strengthens the skin.

The above-mentioned seaweed is effective for eliminating fatigue by improving the function of the liver, finishing the skin, strengthening the bones and muscles, strengthening the heart, and reducing nervous breakdown and insomnia. In addition, it is excellent in hematopoiesis, and it is good for anemia treatment, and it is widely used for treatment of menstrual impurities, uterine inflammation and chronic constipation. In addition, since the above-mentioned sewage contains starch, crude fat, emodin, chrysophanol, lecithin and the like, it is effective for tonic action, lowering of hyperlipemia and hypoglycemic action , The lecithin is effective for antibacterial activity, antioxidant activity, anticancer activity and anti-inflammatory activity.

Resveratrol, which is abundant in sewage, is a substance belonging to the polyphenol family, which is an antioxidant found in plants. Especially, resveratrol is contained in a large amount in red wine. Resveratrol has been known to have anticancer and antioxidant properties in the meantime, and it is also effective in preventing blood clotting, which can reduce heart arterial injury and cause heart attacks and strokes.

On the other hand, the cosmetic composition may contain 30 to 70% by weight of the desalted lava sea water and 0.1 to 10% by weight of the complex extract as an active ingredient based on the total weight.

If the content of the desalted lava waters is less than 30% by weight, the content of the lava water is insufficient and the dispersibility of the complex extract may be deteriorated. If the content of the complex extract is more than 70% by weight, The improvement effect may not be sufficiently realized. If the content of the complex extract is less than 0.1% by weight, it is difficult to realize a sufficient effect of the active ingredient. When the content of the complex extract is more than 10% by weight, the content of the sea salt and other components is relatively decreased, May not be properly exercised.

According to one embodiment, the complex extract may be composed of 20 to 60 parts by weight of the volcanic stone, 20 to 60 parts by weight of a persimmon leaf extract, 10 to 30 parts by weight of a mandarin bark extract, and 20 to 60 parts by weight of a sulfo extract.

When the variation in the mixing ratio of the complex extract is large, the skin improvement effect derived from the active ingredient of each extract may not be suitably implemented, so that the mixing ratio can be appropriately controlled in consideration of the working environment and the quality of the final product . The volcanic stone clusters, the persimmon leaf extract, the mandarin orange peel extract and the sulfurous acid extract are preferably mixed at a weight ratio of 2: 2: 1: 2, and an optimal skin improving effect derived from the active ingredient .

According to one embodiment, the combined extract may be extracted with one or more solvents selected from the group consisting of water, lower alcohols of 1 to 4 carbon atoms, acetone, ethyl acetate, butyl acetate, and 1,3-butylene glycol .

In one embodiment, the alcohol may be ethanol at a concentration of 60 to 90%.

The extraction ratio of the active ingredient contained in the raw material may be different depending on the polarity of the solvent. Among the solvents, alcohols having excellent selectivity in the extraction of physiologically active substances of the raw materials may be preferable, and ethanol having the most selectivity among the alcohol types is most preferable. The optimal skin improvement effect can be realized by the ethanol extraction.

Particularly, since water and ethanol have different polarities, effective components extracted depending on polarities may be different, so that the concentration of ethanol can be appropriately controlled so that an optimal skin improving effect can be realized. However, the ethanol concentration may be 60 to 90%, and if the concentration is less than 60%, the active ingredient may not be extracted sufficiently, and if it is more than 90%, an adequate yield may not be realized.

The cosmetic composition may be used for moisturizing the skin or for shrinking pores or for whitening, and the cosmetic composition may be used as a softening agent, a convergent lotion, a nutritional lotion, a lotion, a nutritional cream, a massage cream, an ampule, a pack, a gel, a mask sheet, Foam, and cleansing water.

The cosmetic composition may be appropriately blended with other ingredients within the range of not hindering the object of the present invention depending on the type of the active ingredient, the purpose of use, and the like in each formulation.

Also, depending on the quality or function of the final product, there may be used various additives such as a fatty substance, an organic solvent, a solubilizing agent, a thickening agent, a gelling agent, a softening agent, an antioxidant, a suspending agent, a stabilizer, a foaming agent, A surfactant, a stabilizer, a stabilizer, an antioxidant, an antioxidant, an antioxidant, a preservative, a barrier agent, a wetting agent, an essential oil, a dye, a pigment, a hydrophilic or lipophilic active agent, And may further comprise adjuvants commonly used in cosmetics or dermatology, such as any of the other ingredients.

However, it is preferable that the adjuvant and the mixing ratio thereof are appropriately selected so as not to affect the preferable properties of the cosmetic composition according to the present invention.
