To maintain healthy skin, cell membranes are protected by eliminating free radicals mediated by UV radiation or inflammatory reactions that occur during metabolic processes in the body, and already damaged cells must be regenerated by active metabolism.

Aging involves not only free radicals but also an enzyme called MMP-1. In vivo, the synthesis and degradation of extracellular matrix such as collagen is properly regulated, but the synthesis decreases as aging progresses, and the substrate is an enzyme that degrades collagen. The expression of metalloproteinase (MMP-1) is promoted, thereby reducing the elasticity of the skin and forming wrinkles. In addition, these degrading enzymes are also activated by ultraviolet irradiation.

In addition, the skin may be aged by pigmentation, and pigments affecting skin color include melanin, melazoid, carotene, hemoglobin, and the like. The most important of these is melanin, and the biggest factors affecting the biosynthesis of melanin are ultraviolet rays and hormone secretion in the body. Melanin plays an important role in preventing or damaging the skin from ultraviolet rays by absorbing or scattering ultraviolet rays. There is no special maximum absorption wavelength and absorbs the light of the whole area. Sometimes melanin itself generates free radicals, other substances are reduced or oxidized by catechol or quinone in the melanin structure, and melanin itself exhibits the properties of free radicals.

The biosynthesis of melanin is brown, eumelanin through a series of oxidation processes starting with the conversion of tyrosine, an amino acid, from the melanocytes of melanocytes to tyrosinase and conversion to dihydroxy phenylalanine. It is formed of a polymer of). This biosynthesis process is carried out in a special type of brown intracellular organelles called melanosomes. Melanosomes, including melanin granules, move from the periphery of the nucleus to the dendritic end, and then into the cytoplasm by the phagocytosis of keratinocytes. Accumulate around the nucleus of the site.

From the above results, it was confirmed that the cosmetic composition containing the extract of the germinated Astragalus germinated from the Astragalus extract of the present invention as an active ingredient has an excellent skin elasticity effect.

Experimental Example  9: Measure skin whitening effect

Experimental Example 9 measured the skin lightening effect for each cream prepared in Example 2 and Comparative Example 2.

The experimenter was 15 women aged 20-35 years and applied the cream of Example 2 to the right side of the face and the cream of Comparative Example 2 to the left side of the face twice a day for 2 consecutive months. After completion of the test, the change in color brightness (ΔL) was measured by using an image analyzer and chromameter (Minolta CR300) on the left and right sides of the face. The effect was measured according to the following classification, and the whitening efficacy was evaluated by classifying it into 7 grades (-3: very worse, -2: worse, -1: slightly worse, 0: no change, 1: Slightly improved, 2: improved, 3: highly improved)

Change in brightness of skin color (ΔL) Objective evaluation of the skilled person Subjective Evaluation of the Subject Experimental product Example 2 Comparative Example 2 Example 2 Comparative Example 2 Example 2 Comparative Example 2 medium 5.0 2.2 2.7 1.8 2.8 1.6

As a result of measuring the skin whitening effect (Table 10), Example 2, which is a cream containing the extract of germinated yellow color, showed better results than Comparative Example 2 in all of the brightness change of the skin color, the objective evaluation of the skilled person, and the subjective evaluation of the subject. Was confirmed to be excellent.

From the above results, it was confirmed that the cosmetic composition containing the extract of germinated Astragalus germinated from the Astragalus extract of the present invention as an active ingredient has an excellent skin whitening effect.
