Description

[0001] The present invention relates to a composition for improving skin condition comprising isostearic acid,

More particularly, the present invention relates to a cosmetic composition, a pharmaceutical composition, and a health food which have excellent effects on blackening, wrinkling, improvement in elasticity, or moisturization of the skin.

Due to the economic growth, the interest in the appearance as well as the health is increasing, and the desire to keep skin and keep healthy is also increasing. In recent years, not only healthy skin maintenance but also self-tanning products have been increasingly used to make skin look healthier. Self-tanning can avoid photo-aging due to overexposure to ultraviolet light, and it is possible to produce a tanning effect even in a season when sunlight does not shine. Recently used self-tanning products have been combined with keratin in the stratum corneum, such as Erythrulose and Dihydroxyacetone, to temporarily dye the skin and dye it. However, in the case of dihydroxyacetone, the skin tone is often not uniform according to the usage method, and there is a problem that the skin is smudged due to peeling of the keratin, and the erythrulose is colored with a more uniform skin tone, . In addition, it has been reported that exposure to ultraviolet light within 24 hours after application to the skin promotes active oxygen production of the skin.

In addition, gray hair generally occurs when the age is higher, giving the feeling of old age, and gray hair, especially at a young age, causes stress. White moths are more prominent in Oriental populations with black hair than white ones with bright hair color, and are being studied in health and beauty and psychology. Melanin is divided into red-yellow Pheomelanin and black-brown Eumelanin. Melanin in hair is an important factor that determines the color of hair. Melanin produced in the melanocyte present in the hair, After being transferred to the cortical cell keratinocytes, the hair moves upward with the growth of the hair. The gray hair, recognized as a phenomenon of physiological aging, is caused by a decrease in the number of hair melanocytes and a decrease in the production of melanin due to a decrease in function of melanocytes. Dyeing is currently used as a solution to white moth, but dyeing must be re-pigmented by growth of gray hair in a temporary manner, and the ingredients contained in the dye of the hair dyes become irritants and cause contact dermatitis or skin allergy It is becoming a problem.

Collagen is a major substrate protein produced in the fibroblasts of the skin and exists in extracellular epilepsy. Its important functions are mechanical durability of the skin, resistance of connective tissues and binding force of tissues, support of cell adhesion, cell division and differentiation (Induction of growth of an organism or wound healing) are known. Such collagen is reduced by photoaging by age and ultraviolet irradiation, and collagenase activity, which degrades collagen, promotes collagen reduction. This is known to be closely related to the formation of wrinkles in the skin.

In addition, Elastin fiber forms crosslinks with collagen and is a skin constituent important for wrinkle formation involved in skin elasticity. The deficiency and aggregation of elastin fibers and the marked increase in the activity of the elastin degrading enzyme Elastase have been found to be one of the causes of skin wrinkles. It is known that Elastase is the only enzyme capable of degrading elastin, and its inhibition can fundamentally reduce the wrinkles of the skin.

On the other hand, collagen and elastin fibers are substrate proteins that play an important role in water retention in the dermal layer. These protein proteins adsorb moisture and increase the water holding capacity inside the structure, thereby allowing the skin to maintain proper moisture content. And it is known to be involved in maintaining the elasticity of the skin.

In addition, the elastic fiber produced in the fibroblast of the skin forms a cross-link with collagen, and is a skin constituent important for wrinkle formation which is involved in skin elasticity. Deficiency and decomposition of elastic fibers were found to be one of the main factors of skin wrinkle formation and elasticity reduction.

The fibrillin-1 protein, which is a constituent of elastic fibers, is a type of microfibril that exists outside the cell and is known to function as a skeleton when elastic fibers are formed. Fibrillin acts as an adhesive to help each part of our body bind and maintain. Mutations in the fibrilin-1 gene are caused by the presence of Marfan syndrome, which causes abnormalities in the lungs, skin or skeletal system. It was known to be the cause. Recently, it has been found that fibrilin-1 acts as a reservoir of TGF-beta.

Presently, retinoids, adenosine, animal placenta-derived proteins, chlorella extract, and the like are known to improve wrinkles. The best known retinol promotes collagen synthesis and inhibits elastase enzymes, but it is unstable. When applied to the skin, it has a limited use due to safety problems such as irritation and redness, and chlorella extract has little effect, It is known that it is difficult to expect a wrinkle-improving effect.

Glycation generally refers to a reaction in which a simple sugar such as glucose or fructose forms a covalent bond to a protein or fat that occurs without involvement of the enzyme. Saccharification takes place through a series of complex chemical reactions known as Amadori rearrangement, Maillard reaction, which results in the formation of advanced glycation endproducts (AGEs).

On the other hand, the glycation process of the protein does not involve the enzymatic action, so it occurs slowly, and as a result, the protein having a longer half-life such as collagen has more influence. Analysis of the final glycation products revealed that the more aged the glycated collagen was accumulated, the accumulation of the final glycated product changed the protein to a harder and more brittle state, and the glycated collagen was found in the extracellular matrix of the dermal layer (Dyer, DG et al. , The Journal of Clinical Investigation, 9, p. 2463, 1993), by inhibiting collagen from forming a proper structure and thereby reducing skin elasticity and promoting wrinkle formation.

Aminoguanidine, pyridoxamine, and aspirin are known to inhibit glycosylation. However, these substances are limited in their use due to the safety of the skin, There is a problem that can not be expected.

Therefore, it has been found that it is safe for the living body, the effective ingredient is safe to the skin and the stability is high, and the anticalcification, the blackening, the wrinkle improvement, Development of a component for improving elasticity is urgently required.
