preparation example Construction

[0025] Specifically, the preparation method of the usnea tremella fermented extract of the present invention comprises: the step of sterilizing the usnea; moistening the sterilized above-mentioned usnea in the culture medium; inoculating the tremella to the moistened above-mentioned usnea a step of obtaining a fermented product by fermenting the mycelium; and a step of extracting the fermented product with an extraction solvent.

[0026] Hereinafter, each step will be described in detail.

[0027] First, sterilize the usnea.

[0028] Sterilization is to utilize high-pressure steam sterilizer (autoclave) to sterilize all bacterial strains that exist in Usnea, carry out under the routine condition of industry. As an example, the step of sterilizing usnea is carried out by performing heat treatment at a temperature of 100° C. to 125° C. for 5 minutes to 30 minutes.

[0029] Next, the sterilized usnea was moistened in the culture medium.

[0030] By making usnea moist in the cu...

[0051] Wet after adding 8 wt% of sterilized usnea to sabouraud dextrose broth. After that, relative to the moist Usnea, inoculate 30wt% of the cultured white fungus hyphae, and culture them statically for 5 days, 10 days, 20 days, and 30 days respectively at a temperature of 30°C. 100 g of the obtained fermented product was put into 70% ethanol with a weight ratio of 20 times and extracted at a temperature of 25° C. for 4 hours, then filtered to remove insoluble substances such as bacteria cells, and the solvent was removed by a rotary vacuum concentrator. The yield of the obtained Usnea fermented extract is shown in Table 1 below.

The positive control group and the extracts of Examples 1 to 4 and Comparative Example were added at 100 μg / ml, and cultured for 48 hours. After culturing, the amount of IC-type procollagen titanium (PIP) was measured on the supernatant of each well using a collagen kit (Takara Bioengineering, Takara, Japan), and the amount of collagen synthesized therefrom was measured. figure 1 And Table 2 shows the results.

Abstract

The present invention relates to a cosmetic composition, which contains Usnea tremella mycelia fermented extract as an active ingredient. It is extracted, so it can improve wrinkles and improve skin elasticity. According to the present invention, the cytotoxicity of the Usnea extract can be significantly reduced by fermenting the tremella mycelia, so it is safe for the skin, and because it has excellent bone collagen and elastin which the Usnea extract does not have. Synthetic function, so it is advantageous in cosmetic compositions for improving skin wrinkles and improving skin elasticity.

Description

technical field [0001] The present invention relates to a cosmetic composition in which the Usnea fermented extract of Tremella mycelium is used as an effective ingredients, so it can have the effect of improving wrinkles and improving skin elasticity. Background technique [0002] Skin aging is due to the oxidative damage of organisms by free radicals. In living organisms, the attack of oxidants or free radicals and the defense of antioxidants form a close coordination. However, since the defense of antioxidants is not perfect, biological molecules such as lipids, proteins, nucleic acids, and enzymes, which are the constituent molecules of organisms, are continuously subjected to oxidative damage by oxidants or free radicals, and their oxidation reaction products will be accumulate with age. [0003] In particular, since the skin is always in contact with oxygen, it is subjected to the oxidative burden of exposure to ultraviolet rays, etc., causing damage to the antioxid...
