Description

Skin agent composition containing fermented Arenaria serpyllifolia L. extract}

The present invention relates to a composition for external application for skin, and more particularly, to a composition for external application for skin containing a filtrate obtained by fermenting a vinegar extract of Seolcho belonging to the genus Japonica.

Human skin is constantly changing with age. Skin aging is largely divided into natural aging (or endogenous aging) and external aging (EB Doris, Cosmetics & Toiletories , 111, 31-37, 1996). While control is difficult, external aging is relatively easy to control because it is influenced by environmental factors. Representative external aging factors include ultraviolet rays, and the most prominent external aging phenomenon is wrinkle formation (HW Daniell, Ann Intern Med, 75, 873-880, 1971, GL Grove, J Am). Acad Dermatol , 21, 631-637, 1989, CE Griffiths et al, Arch Dermatol , 128, 347-351, 1992).

Skin exposed to ultraviolet rays produces free radicals and reactive oxygen species, causing skin cancer, phototoxicity, autoimmune disorders, photosensitivity and skin aging (Norins, J. Invest . Dermatol . , 39: 445, 1962; Cadenas, Ann. Rev. Biochem., 58:79, 1989). Synthesis and degradation of extracellular matrix such as collagen is regulated in vivo, but the synthesis decreases as aging progresses, and the expression of substrate metalloproteinase (MMP), an enzyme that breaks down collagen, promotes the expression of skin elasticity. It is lowered and wrinkles are formed.

On the other hand, melanin is converted from tyrosine to dopa and dopaquinone by the action of tyrosinase existing in pigment cells, and is generated by dopachrome. Melanin is present in the skin, protects the body from ultraviolet light and has an important function in regulating hormone secretion in the body. However, when melanin is overproduced, it is known that it forms spots and freckles, promotes skin aging, and plays an important role in skin cancer induction. Therefore, research and development are actively conducted to prevent melanin overproduction. Ascorbic acid (JP-A 4-9320), hydroquinone (JP-A 6-192062), kojic acid (JP-A-56-7710), arbutin (JP-A 4-93150), and plant extracts have already inhibited tyrosinase. It has been used as a whitening cosmetic due to its activity, but its stability in cosmetic formulations is deteriorated, resulting in coloration, off-flavor, unclear efficacy and effects at the biological level, or safety issues, which limit its use. .

On the other hand, atopic dermatitis is a representative disease in people with atopic dermatitis. Although the cause of atopic dermatitis has not been clarified yet, about 70% of patients with atopic dermatitis have a history of atopic dermatitis and allergic predisposition. It is known to be one of the most common allergic diseases, such as allergic rhinitis, asthma, etc., because it is understood as one of the diseases caused by genetic factors or immune diseases. In the treatment of atopic dermatitis, corticosteroids such as corticosteroids are expected to have high pharmacological effects. However, side effects of corticosteroids have become a problem. It is also well known that a dramatic aggravation of lesions occurs later. As a countermeasure for such side effects, nonsteroidal anti-inflammatory drugs or antihistamines, which do not contain hormones such as corticosteroids, are used, but since they are difficult to cure, development of atopic dermatitis improving agents or treatments without side effects is very urgent.

Recently, in order to reduce skin irritation caused by various chemicals and the like, much attention has been focused on functional cosmetics having functions such as antioxidants, wrinkle relief, whitening, and itching relief. For example, US Pat. No. 5,972,341 relates to the antiwrinkle effect of Commiphora mukul extract, and Japanese Patent Application Laid-open No. Hei 9-672662 relates to seaweed extracts having a hyaluroronidase inhibitory effect. Japanese Patent Application Laid-open No. Hei 10-85905 relates to the skin texture improvement effect of Fucoidan extracted from Wakame, Japanese Patent Application Laid-open No. Hei 2-245087 relates to the antioxidant effect of the genus Sargassum extract, Republic of Korea Patent No. 0431076 is a cosmetic composition for improving the healing of atopy skin, including white powder, purple, echinacea and fermented soybean extract, Korean Patent No. 0511494 is an extract for the treatment of atopic dermatitis, including sewage, leaf, illite and Korean Patent Application Publication No. 2004-0011584 discloses a composition for the purification and mixing of natural ingredients such as licorice, changja, safflower, and pork fat.

Soc., 564: 247). -256, 1994), in particular, a flavonoid or a derivative thereof, wherein inflammatory components, as well as the pharmacological effects such as anti-allergic, anti-cancer and diabetes, is known (Middleton et al, Pharmacol Rev, 52:... 673, 2000 ), It has been reported to be excellent in antioxidant activity such as radical scavenging activity caused by ultraviolet rays and lipid peroxidation inhibitory activity and inhibition of tyrosinase activity which is a whitening effect (Nijveldt et al., Am . J. Clin . Nutr . , 74: 418, 2001) .

In general, hydrophobic substances are more effective for skin penetration than hydrophilic substances.The components distributed in the stratum corneum are ceramides, which are more effective for interacting with hydrophobic substances than hydrophilic substances, and the hydrophobic substances are more easily skinned. Because it can pass through layers.
