Description

A skin-care agent containing Dictyophora indusiata fruit body extract or Dictyophora indusiata mycelium extract containing an extract of Fusarium oxysporum f.

The present invention relates to a composition for external application for skin containing an extract of Fagaceae mushroom Fruit body or an extract of Fungus mushroom mycelium. More specifically, the present invention relates to a composition for external application for skin comprising a filtrate obtained by fermentation of a filtrate obtained from an extract of Fagaceae mushroom Fruit body, To a composition for external application for skin.

Skin aging can be divided into two types: intrinsic (chronological aging) and phtoaging (Gilchrest BA: J. Am . Acad . Dermatol ., 21, 610-613 (1989)]. Endogenous aging is a naturally occurring aging phenomenon that is accompanied by decreased physiological function of the body as age increases [Braverman IM et al . : J. Invest . Dermatol ., 78, 434-443 (1982)]. Photoaging means that the skin is repeatedly exposed to light to change the appearance or function of the skin [Ridder GM et al . : J. Am . Acad . Dermatol ., 25, 751-760 (1991)]. In addition, skin aging can be caused by active oxygen species activated by ultraviolet rays, stress, disease states, environmental factors, wounds, and aging. When such conditions are deepened, the antioxidant defense network existing in the living body is destroyed, It damages tissues and promotes adult diseases 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. In particular, the oxidation of proteins causes severe hyperinflammation of collagen, hyaluronic acid, elastin, proteoglycans, and fibronectin, which are connective tissues of the skin, which interferes with skin elasticity. Mutation, cancer induction, and immune function.

Therefore, it is necessary to protect the cell membranes by abolishing reactive oxygen species that are mediated by the body's metabolic processes, ultraviolet irradiation, and inflammatory reactions, and regenerate already damaged cells by active metabolism to proliferate the cells Can be restored and healthy skin can be maintained. In aging, not only active oxygen species but also MMP (Matrix metallopretease) is involved. In vivo, the synthesis and degradation of extracellular matrix such as collagen are properly regulated, but the synthesis is reduced as aging progresses and the collagen- Expression of matrix metalloproteinases (MMPs) is promoted, and skin elasticity is lowered and wrinkles are formed. These degrading enzymes are also activated by exposure to ultraviolet light. Therefore, there is a demand for development of a substance capable of controlling the activation of MMP induced in the cell by ultraviolet light or inhibiting its activity. Until now, the raw materials used as cosmetic materials mostly inhibited only the activity of degrading enzyme (MMP).

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. (Japanese Patent Laid-open No. 4-93050) and plant extracts inhibit tyrosinase (Japanese Patent Laid-open Publication No. 4-9320), hydroquinone (Japanese Patent Laid Open No. 6-192062), kojic acid Activity and is used as a whitening cosmetic, but its stability is poor in cosmetic formulations, it is decomposed to cause coloration, odor, or efficacy at a biological level, its effect is unclear, or its safety is a problem. to be.

Atopic dermatitis is a common disease in people with atopic allergies. Although the cause of atopic dermatitis has not yet been clarified, atopic dermatitis has a history of atopy in 70% of the patients, And it is understood to be one of diseases caused by genetic factors or immune diseases because it is accompanied by allergic diseases such as allergic rhinitis and asthma. In the treatment of atopic dermatitis, medicines such as corticosteroids, which can expect high pharmacological effects, are used, but side effects of corticosteroids are problematic, and the use of corticosteroids causes the rebound It is also well-known that a later severe worsening of the affected part occurs. As a countermeasure for such side effects, a non-steroidal anti-inflammatory agent or an antihistamine agent which does not contain a hormone such as adrenocortical hormone is used but it is very difficult to develop a remedy or therapeutic agent for atopic dermatitis without side effects because it is difficult to cure.

Recently, much attention has been focused on functional cosmetics having functions such as antioxidation, wrinkle reduction, whitening, and itching relief obtained from natural extracts in order to reduce skin irritation caused by various chemical substances and the like. For example, U.S. Patent No. 5,972,341 discloses a wrinkle-reducing effect of an extract of Commiphora mukul. Japanese Patent Application Laid-Open No. 9-672662 discloses an extract of seaweed having a hyaluronidase inhibitory effect, Japanese Patent Application Laid-Open No. Hei 2-245087 discloses an antioxidative effect of Sargassum sp. Extract on the skin texture improvement effect of Fucoidan extracted from Wakame, Patent No. 0431076 discloses a cosmetic composition for improving the healing of atopic skin including a white, black, echinacea, and fermented soybean extract, Korean Patent No. 0511494 discloses an extract and composition for treating atopic dermatitis including at least one of Hashuo, .

In addition, male-pattern alopecia are male hormone-dependent and have a direct relationship with the amount of male hormone. Accordingly, many studies for prevention and treatment of alopecia through inhibition of male hormone activity have been reported. On the other hand, when the function of the sebaceous gland is activated by the increase of the secretion of the male hormone, the excess sebum produced in the hair follicle is stagnated in the hair follicle due to the overgrowth of the hair follicle wall. 5-alpha-Reductase is one of the male hormones present in male hormone reactive tissues such as sebaceous glands, hair follicles, prostate, and epididymis, as a result of male hormone-induced hair loss and acne. , An enzyme involved in the metabolism of testosterone into dihydrotestosterone, and requires NADPH for its conversion. In addition, testosterone is involved in male sexual dysfunction, skeletal muscle increase, male external genitalia, scrotum growth, spermatogenesis and the like, and dihydrotestosterone is involved in the relevant tissues such as acne, sebum increase, hair loss and enlargement of the prostate. In particular, after puberty, excessive secretion of male hormones causes acne and hair loss. To prevent excessive production of dihydrotestosterone, an active form of male hormone produced by 5-alpha-reductase, 5-alpha-reductase Studies have been actively conducted to develop anti-hair loss and anti-acne agents using an azide inhibitor.

In order to solve such skin problems, many cosmetics using natural products or medicinal and edible mushroom extracts have recently been developed to reduce skin irritation caused by various chemical substances and the like. As the cosmetic compositions using the mushroom extracts known so far, there have been proposed various cosmetic compositions such as snow flake (Korean Patent No. 0340185), Situ mushroom, Chima mushroom (Korean patent No. 0681703, No. 0295623), Leaf mushroom (Korean patent No. 0438009) And the research on the anti-aging effect of these extracts has been continued.

Mushrooms which are used for medicinal and edible purposes are many examples and kinds, but mushrooms which are used and studied as cosmetic composition are still known as a part.
