Description

Composition whitening cosmetics containing special herbal extracts

The present invention is a mixture of white paper, white, baekryeom, white nap, baekjaja, cheonbuja and natural extracts in the conventional cosmetic composition, the skin pigment causing melanin, freckles, blemishes and other skin problems that are apparent skin problems deposition The present invention relates to a whitening cosmetic composition containing a specific plant extract having excellent inhibitory effect and excellent skin whitening function, as well as excellent product stability and safety to skin.

In general, the skin functions to protect the body from ultraviolet rays. That is, when ultraviolet rays are irradiated, the formation of tyrosinase increases in melanocytes (melanocytes) to produce and release black melanin pigments, which are distributed on the epidermal cells, thereby blocking the natural screening. Screening) function. At this time, ultraviolet rays and tyrosinase play the most important role in the melanin production pathway. In particular, the activity of tyrosinase is promoted in melanin-forming cells and melanin production is increased, which eventually blackens the skin and blocks ultraviolet rays. However, excessive formation and deposition of melanin pigments causes appearance problems such as blackening of the skin, blemishes, and freckles. Accordingly, whitening cosmetics are required to prevent their skin symptoms.

However, the conventional whitening cosmetics have a problem that the stability of the product is not good, and thus the skin whitening effect is unclear, and the stability to the skin is also lowered. In particular, the conventional whitening cosmetics have a problem in which the whitening effect rapidly decreases over time. there was. That is, the conventional whitening cosmetics are substances for skin whitening, mainly ascorbic acid, kojic acid, kojic acid derivatives, hydroquinone, arbutin, and gourd extracts, pine extracts, and lichen extracts. Some of the plant extracts are used, such as extracts from the medicinal plant, and the extracts of ascorbic acid and kojic acid are very unstable in air, heat, and light, and cosmetics containing a small amount of browning occur after several weeks at room temperature, and arbutin is cytotoxic. There is a known problem such as poor skin safety. In addition, the whitening cosmetics containing a plant extract component has a limitation in its efficacy or a problem in which the above-described problems exist in some cases.

The present invention has been made in view of the above problems, and not only contains and selects a substance that inhibits the production of melanin while blocking ultraviolet rays for skin whitening, and also releases melanin from the melanocytes and removes keratin. Through promoting mechanism (Mechanism) through the multifunctional function for skin whitening and to provide a whitening cosmetic composition containing a specific plant extract excellent in usability, which will be described in detail with an embodiment of the present invention as follows. .

The present invention not only selects and contains a substance that inhibits the production of melanin while blocking ultraviolet rays for skin whitening, and also through a mechanism that promotes the release of melanin in melanocytes with the removal of keratin. In order to exert a multi-functional function for skin whitening, the extract obtained by mixing white paper, white powder, baekryeom, Baekjap, Baekjaja, and cheonhwa in a predetermined content ratio based on dry medicinal herbs in a conventional cosmetic composition, extracted with a polar solvent such as ethanol It will consist of a certain content according to the formulation of.

As mentioned above, in connection with the whitening cosmetics, in the past, it was based on the inhibition of the activity of tyrosinase enzymes involved in the production of melanin pigment and the whitening mechanism of reducing the newly produced melanin, but the present invention is stable and effective. As a result of a long-term mechanism of melanin production and control along with the development of whitening ingredients, the activity of tyrosinase and tyrosinase enzymes are not only inhibited by tyrosinase in the melanocytes, but also in melanocytes. It can be expected in the whitening cosmetic composition of the present invention that the cosmetic composition is configured to deal with the problems of the whitening mechanism, such as suppression, promoting the release of melanin in a variety of ways to exhibit more excellent whitening effect.
