Description

TECHNICAL FIELD The present invention relates to a composition for skin regeneration, anti-wrinkle, antioxidant, anti-inflammation, and skin whitening,

The present invention relates to a composition for skin regeneration, wrinkle improvement, antioxidation, anti-inflammation and skin whitening.

Collagen is a major substrate protein produced in fibroblasts of the skin and exists in extracellular epilepsy. Its important functions are mechanical rigidity of skin, resistance of connective tissues and binding force of tissues, support of cell adhesion, division of cells and differentiation Growth or wound healing) are known. Such collagen is reduced by aging and photo aging caused by ultraviolet irradiation, which is known to be closely related to the wrinkling of the skin. Also, in recent years, extensive research on skin aging has developed, and important functions of collagen in skin have been revealed.

Effective ingredients promoting collagen synthesis and exhibiting wrinkle-reducing effects are known. For example, retinoic acid, transforming growth factor (TGF) [non-patent document 1], animal placenta-derived protein [Patent document 1], betulinic acid [Patent document 2], chlorella extract [ Patent Documents 3 and 4] are known as collagen synthesis promoting substances. However, the above-mentioned effective ingredients are limited in the use amount due to safety problems such as irritation and redness when applied to the skin, or have insufficient effect, so that the effect of improving the skin function by promoting the collagen synthesis of the skin can not be expected.

On the other hand, active oxygen introduced from the outside of the living body or generated in the living body causes many problems such as promoting aging of the living body, cancer, and the like. Therefore, the development and research of antioxidants that inhibit oxidation by active oxygen have been performed. Antioxidants are widely distributed in copper and plants. Many phenolic compounds, flavonoids, tocopherols, vitamin C and selenium are known in fruits and vegetables. However, the antioxidant substances present in nature can not be expected to have practically sufficient effects in skin application. Therefore, although synthetic antioxidants having excellent antioxidant ability and low cost are widely used, their use is restricted due to safety concerns such as human side effects.

In addition, inflammation is an immune response of a human body in response to a wound or disease, and oxidative stress such as ultraviolet rays, active oxygen, free radicals, etc. activate inflammatory factors and cause aging of various diseases and skin. The vasoactive polypeptide, kinin, plasmin and complement, have vasodilatory and contraction and chemotaxis effects, as well as lymphokines such as interleukin-6 (IL-6) Phosphorus and arachidonic acid are responsible for inflammation. Arachidonic acid is metabolized through inflammatory mediators such as prostaglandin and lukotrienes via two pathways: cyclooxygenase or lipooxygenase, mediating a variety of inflammatory responses.

On the other hand, in order to eliminate inflammation, elimination of inflammation source, reduction of vital reaction and symptoms is called anti-inflammatory. To date, substances used for antiinflammatory purposes include flutenamic acid, ibuprofen, benzydamine, indomethacin, and steroids, prednisolone, , Dexamethasone, and the like. It is also known that allantoin, azene, hydrocortisone and the like are effective for antiinflammation. However, these materials are limited in their use due to safety of skin, .

In addition, it is the desire of everyone to have a whiter skin. It is genetically determined by the concentration and distribution of melanin in human skin, but is also influenced by environmental or physiological conditions such as sunlight, fatigue, and stress. Melanin is produced by a nonenzymatic oxidation reaction after tyrosine, an amino acid, is converted to DOPA or dopaquinone by an enzyme called tyrosinase. Thus, the pathway through which melanin is made is known, but the mechanism by which melanin synthesis, the previous step in which tyrosinase acts, is not yet elucidated.

On the other hand, commonly known whitening ingredients include substances inhibiting the activity of tyrosinase enzymes such as kojic acid and arbutin, hydroquinone, vitamin C (L-Ascorbic acid) There are plant extracts. By inhibiting the synthesis of melanin pigment, they can brighten the skin tone to realize skin whitening, and it is possible to improve skin hypercholesterolemia such as stain or freckles due to ultraviolet rays, hormones or heredity. However, when applied to skin, there is a problem that the use amount is limited due to safety problems such as irritation and redness, or the effect is insignificant, so that a practical effect can not be expected.

Accordingly, it is possible to provide a method for improving the skin regeneration, wrinkle improvement, antioxidant, anti-inflammation and whitening activity, which are more safe and effective in the living body and more effective than the substances having the existing skin regeneration, wrinkle improvement, antioxidant, anti- It is urgently required to develop a component having an amino acid sequence.
