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), animal placenta-derived protein, betulinic acid, and chlorella extract 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, 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 tyrosine, which is 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 tyrosinase enzyme activity such as kojic acid and arbutin, hydroquinone, vitamin C (L-ascorbic acid), derivatives thereof, 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.

Therefore, there is a desperate need for development of ingredients having skin regeneration, wrinkle improvement, antioxidative and whitening activity, which are more safe than the living body, have a stable active ingredient, and are more effective than the substances having existing skin regeneration, wrinkle improvement, antioxidant and whitening effect Is desired.

Accordingly, the present invention is to solve the above-mentioned problems, and to provide such a useful use of a new active ingredient, i.e., an active ingredient, which is safe to human body and has good skin regeneration, wrinkle improvement, antioxidant and whitening effect.

In other words, a problem to be solved by the present invention is to provide a composition comprising the active ingredient having excellent efficacy as an active ingredient.
