Description

[0001] The present invention relates to a cosmetic composition containing an extract of Fermented Quinona as an active ingredient,

The present invention relates to a cosmetic composition for improving whitening, skin aging, and skin wrinkles containing a fermented extract of Chenopodium quinoa Willd . As an active ingredient.

A variety of physical and chemical changes occur in human skin during the aging process. The cause of this phenomenon is divided into intrinsic aging and photo-aging. Free radicals can be caused by activation of ultraviolet rays, stress, disease state, environmental factors, wounds, and aging. When such state is deepened, the antioxidant defense network existing in the living body is destroyed, And aging. More specifically, lipids, proteins, polysaccharides and nucleic acids, which are major constituents of the skin, are oxidized to destroy skin cells and tissues, resulting in skin aging.

Skin color of a person is determined by melanin, hemoglobin, carotene, etc. Among them, melanin plays the most important role. In addition to determining human skin color, melanin also performs skin protection functions such as ultraviolet absorbing action, free radical scavenger and the like. However, excessive production of melanin due to external environmental changes such as overexposure of ultraviolet rays, air pollution, stress, and the like causes pigmentation in the skin, which causes blackening of skin, freckles, and the like. Blackening of the skin is caused by the reaction of the skin cells to internal and external factors, and a typical factor is due to ultraviolet exposure. That is, when the skin is exposed to ultraviolet rays, tyrosinase is activated. By the oxidation process in which tyrosinase acts on tyrosine present in skin tissue to generate dopa (DOPA) and dopaquinone, In melanocytes in melanocytes, a polymer called melanin is synthesized. This melanin is transferred to keratinocytes, which are keratinocytes of skin, and reaches skin surface by keratinization process to protect skin from ultraviolet rays. Thus, melanin is an essential UV inhibitor in the human body, and it also plays an effective role as an effective radical scavenger to remove various radicals that modify biological components such as proteins, lipids, and nucleic acids.

In particular, the oxidation of proteins can cause collagen (collagen), hyaluronic acid, elastin, proteoglycan, fibronectin, and the like that are severely hyperinflammatory reactions and skin elasticity If this gets worse, DNA mutations can lead to mutations, cancer, and immune deficiency. Therefore, it is necessary to protect the cell membrane by destroying the free radicals mediated by free radicals, ultraviolet rays, and inflammation that occur during the metabolism of the body, and to regenerate already damaged cells by vigorous metabolism The skin can quickly recover and maintain healthy skin.

Aging involves free radicals as well as enzyme called matrix metalloproteinase (MMP), a collagenase. That is, synthesis and degradation of extracellular matrix such as collagen in vivo are appropriately controlled, but collagen synthesis is reduced as aging progresses, and expression of matrix metalloproteinase (MMP), an enzyme that degrades collagen, is promoted, And the wrinkles are formed. These degrading enzymes are also activated by ultraviolet irradiation. Therefore, there is a demand for development of a substance capable of modulating MMP expression induced in the cell or inhibiting its activity. Oxygen is an indispensable substance in our life with water, but once it enters our body, it turns into highly active oxygen by various causes to oxidize blood vessel cells. Today, about 90% of the causes of the disease are attributed to this active oxygen. The human body is composed of about 60 trillion cells, and the cell membrane is formed as an impetium, so active oxygen is easily connected. When the oxidation reaction occurs, the unsaturated fatty acid changes to lipid peroxide. This lipid peroxidase damages gene DNA, RNA, protein, cell membrane, and cell structure, leading to cancer, causing many adult diseases, and ultimately causing aging. It is called antioxidant substances that act to prevent cells from oxidizing by neutralizing or eliminating these free radicals. Generally, when peroxidation is caused by lipid active oxygen, which is a constituent of skin cells, the cell membrane structure is modified, resulting in cell permeability, fluidity, inactivation of membrane enzymes and transport proteins, cleavage of protein chains, DNA and RNA damage Skin cells are known to cause aging. For this reason, efforts to remove active oxygen have continued, and as a result, many sulfated materials have been developed. Materials known to have antioxidative action so far include ascorbic acid, beta-carotene, dibutylhydroxyltoluene (BHT), and DL-alpha-tocopherol . However, since these materials are used as synthetic materials, they cause problems of skin safety when they are used for a long period of time or when they are used in large amounts, or they are limited in their use due to problems in stability when they are contained in cosmetics. to be. Many researchers are working hard to solve these problems.

Experimental Example  3. Elastase ( Elastase ) Inhibition activity measurement

Elastase is an enzyme that degrades elastin, an important substrate in maintaining skin elasticity in the dermis. Elastase is also a nonspecific hydrolytic enzyme capable of degrading collagen, another important substrate protein. Thus, the elastase inhibitor has a function of improving the wrinkles of the skin, and the ursolic acid and the like are used as the elastase inhibitor. Elastase is known to be the main cause of wrinkles by decomposing elastin, the insoluble elastic fiber protein of animal connective tissue, and breaking the network structure of dermal tissue of skin. In the dermis of the skin, elastin related to the elasticity of collagen and skin forms a network structure. As the network structure is broken, the elastin is decomposed by elastase, and the skin is wrinkled and wrinkles are generated. do. Therefore, skin aging can be inhibited by decreasing the activity of elastase, an elastin degrading enzyme which is one of the major causes of skin aging. N-succinyl- (L-Ala) 3-p-nitroanilide, S4760, Sigma) The amount of p-nitroanilide produced from the substrate at 37 ° C for 20 minutes was measured at 445 nm. 500 μL of a solution of porcine pancreas elastase (E1250, Sigma) 2.5 U / mL) dissolved in 2 mM tris-HCl buffer (pH 8.6) was added to the test tube, and 50 mM N-succinyl- (L-Ala) 3-p-nitroanilide (500 μg / mL) dissolved in tris-HCl buffer (pH 8.6) was added and reacted for 20 minutes. Elastase inhibitory activity was calculated by the following equation (3) as the absorbance reduction ratio of the sample solution and the non-added sample, and the results are shown in Table 3 below.
