Cosmetic composition for preventing skin aging containing roe deer urine extract {COSMETIC COMPOSITIONS FOR PREVENTING SKIN AGING COMPRISING EXTRACT ASTILBE CHINENSIS VAR. DAVIDII}

The present invention relates to a cosmetic composition for preventing skin aging containing roe deer urinary tract extract, and more particularly, containing roe deer urine extract to promote the proliferation of skin cells, to inhibit the synthesis and synthesis of collagen of fibroblasts, It relates to a cosmetic composition that enhances the expression, has an excellent antioxidant effect and effectively prevents skin aging through skin wrinkle improvement and skin elasticity improvement.

The skin is the largest organ of the human body, occupying about 16% of the total body volume, and an important protective barrier that protects the body from many deadly harmful factors, such as temperature, humidity, and ultraviolet radiation, which are in direct contact with the external environment and are likely to enter the body. Play a role. However, as they age, skin cells are damaged due to various contaminants, strong ultraviolet rays, stress, and malnutrition, and cell proliferation is not performed properly, resulting in wrinkles, loss of elasticity, and keratinization.

Skin aging is largely divided into intrinsic aging and extrinsic aging (Cosmetics & Toiletories, 111: 31-37 (1996)). Endogenous aging is a aging phenomenon that occurs naturally as the physiological function of the skin gradually decreases with age. Clinically, elasticity is reduced, skin texture is rough, deep wrinkles are formed, and pigments are deposited. Dermatol., 130: 87-95 (1994). Exogenous aging refers to the aging phenomenon caused by exogenous factors such as ultraviolet light, reactive oxygen species and stress. These factors lead to rapid aging of the skin, resulting in rough wrinkles on the surface of the skin and a marked decrease in elasticity.

At present, various studies have been conducted to investigate the mechanism of aging of the skin and various causes of skin aging have been identified. When the skin is dried by a change in temperature, a decrease in humidity or wind, the skin physiological activity as a protective barrier against the outside is lowered to promote aging. In addition, when the skin is exposed to harmful free radicals or free radicals, lipid peroxide is produced by oxidative action in the body and causes modification of various proteins constituting the skin.

On the other hand, collagen and elastic elastin proteins, which make up most of the dermis (about 70-80% of the total dry weight of the skin), are the major proteins produced by fibroblasts, and the skin's mechanical firmness, tissue binding strength and elasticity (Journal of the american academy of dermatology, 21: 610-613 (1989)). Collagen decreases with age and with increasing exposure to ultraviolet light. Collagen is classified according to form and structural features, the most well known of which are Type I, II, III and IV. Collagen types I and III constitute the constituents of the cytoplasm of the dermis, and collagen type IV is the major component of DEJ (Dermal Epidermal Junction). Collagen type II is located between the epidermal and dermal layers of the skin to regulate the permeation and transport of substances between the two layers, to control the differentiation of adjacent skin cells and to maintain the firmness of the skin. Collagen and elastin, the major structural components of the skin, are either denatured or reduced in biosynthesis by natural or external stimuli, thereby accelerating skin aging. In addition, the expression and activity of collagenase is also a major factor in accelerating skin aging.

Wrinkle formation and deterioration of skin elasticity are affected not only by the amount of collagen and elastin and the like that form the matrix structure in the dermal layer, but also by the organized state of the component or the degree of interaction between the matrix and skin cells.

Integrin, a type of membrane protein present in skin cells, also plays an important role in skin cell adhesion and cell-protein interactions, which in turn affects skin elasticity. It has been reported that the level of integrin expression is related to the degree of cell adhesion, that is, the skin elasticity. When the level of integrin expression on the surface of fibroblasts induced aging by UV-A and UV-B irradiation is measured It is reported that the level of integrin expression is lower than the level of integrin expression of unirradiated cells (Laetitia Moreau, Cosmetics & Toiletries, 118 (1): 75-84 2003).

Retinoic acid, epidermal growth factor (EGF), TGF (trans-forming growth factor), carcinogenesis factor Cardinale G. et al., Adv.Enzymol., 41, p 425, 1974), animal placental proteins (JP8-231370), betulinic acid (betulinic acid (JP8-208424)), chlorella extracts (JP9-40523, JP10-36283, fibroblast proliferation). . In particular, epidermal growth factor acts as a potent promoter of epithelial cell, endothelial cell and fibroblast cell proliferation, and promotes the movement and proliferation of epithelial cells during epithelial cell defects. Retinol is also described in US Pat. Nos. 4,603,146 and 4,877,805, which have a very effective effect on collagen synthesis and inhibition of degradation to exert skin wrinkle improvement.

However, retinoic acid is unstable, and there is a limit to the amount of use due to stability problems such as irritation and redness when applying the skin. Chlorella extract and the like have little effect, so the collagen synthesis of the skin cannot be substantially expected to improve skin function.

Therefore, there is an urgent need for the development of new collagen synthesis promoters which are safe for living bodies and are more effective than conventional collagen synthesis ability promoting substances.

The present invention is to solve the problems of the prior art as described above, can be applied stably without irritation to the skin, to promote the proliferation of skin cells, to inhibit the synthesis and synthesis of collagen synthesis of fibroblasts and to enhance the expression of integrin The purpose of the present invention is to provide a cosmetic composition capable of preventing skin aging by improving skin wrinkles and improving skin elasticity by having an excellent antioxidant effect.
