Description

Cosmetic composition for reducing skin wrinkles comprising lactobacillus plantarum culture

Technical Field

The present application relates to a cosmetic composition having collagen synthesis effect comprising a single lactic acid culture, and more particularly, to a cosmetic composition for promoting collagen synthesis and improving skin wrinkles comprising a lactobacillus plantarum CJ L P133 culture.

Background

The human skin protects the human body from various oxidants, air pollution, heavy metals, ultraviolet radiation (UV), etc., prevents bacteria, fungi, viruses, etc. from invading the skin, and has the function of preventing water loss as a protective barrier. The structure of the skin is roughly divided into three layers of epidermis, dermis and subcutaneous fat, and the dermis layer, which accounts for 90% of the skin, is composed of collagen, elastin, hyaluronic acid and glycoprotein. Collagen is the major component of skin, an important fibrin protein, which accounts for about 25% of the total weight of human protein. It constitutes most connective tissues and has important roles such as intercellular matrix function, structural support function, induction of cell division and differentiation, provision of skin tensile strength, and the like. It is known that aging, ultraviolet rays, harmful oxygen, etc. cause a decrease in collagen production and destroy the structure thereof, and thus it is closely related to the formation of skin wrinkles. In recent years, deteriorating environmental factors (e.g., fine dust, etc.) cause the breakdown of skin barrier, and thus skin aging is continuously promoted by the decrease in collagen synthesis and the increase in decomposition.

Therefore, it is very important in cosmetics to maximize the effects of each ingredient and minimize the side effects thereof to prevent skin aging. In this regard, there is a need to develop a cost-effective material that promotes collagen synthesis without side effects and an easy-to-use cosmetic comprising the same.

Lactic acid bacteria are bacteria that have a beneficial effect in the human body, producing lactic acid through the fermentation of carbohydrates or fibers. To date, about 400 species of lactic acid bacteria have been found, and about 18 species have been developed as commercial products.

Once lactic acid bacteria enter the human intestinal tract, they secrete specific substances through their own metabolic activities. Since these substances have beneficial effects on the human body, many studies have been made on lactic acid bacteria. The effects of lactic acid bacteria on antibacterial, antioxidant and immunological activities have been reported. In recent years, research has been focused on whitening and moisturizing effects of lactic acid bacteria, and the possibility as a cosmetic material has been increasing. Among lactic acid bacteria, many studies have been made on the action of lactobacillus, and enhancement of immunity, antibacterial action, skin whitening, improvement of atopic dermatitis, and the like have been reported.

Among them, the plant-derived lactic acid bacteria (PO L AB) are lactic acid bacteria isolated from fermented foods of plant materials (e.g., pickles, kimchi, etc.), and are different from dairy-derived lactic acid bacteria.

The lactic acid bacteria of plant origin not only include species at least 10 times more than animal lactic acid bacteria, but also have excellent adaptability to the external environment. In particular, the plant lactic acid bacteria isolated from kimchi having high salt content, low pH and high content of natural antibacterial substances can grow in extreme environments, and thus the plant-derived lactic acid bacteria have excellent productivity of various physiologically active substances.

Representative physiologically active substances may include antibacterial peptides, immunostimulants, gamma-aminobutyric acid (GABA), which exhibit various physiological functions including anti-inflammatory and immunosuppressive effects, and the like. In addition, lactic acid bacteria are heat stable peptides and produce bacteriocins as antimicrobial agents. Bacteriocins are natural antimicrobial proteins or proteinaceous substances produced by a variety of microorganisms, generally referring to substances having bactericidal mechanisms against bacterial strains that are morphologically and phylogenetically similar to the bacteriocin-producing microorganisms. Therefore, the development of cosmetic materials using lactic acid bacteria cultures or lactic acid bacteria fermented plant extracts and the like containing these substances is actively underway, and this progress is in line with the latest trend of being favorable for environmental protection and safety materials.

Nowadays, consumers expect not only general care effects in cosmetics but also various functions thereof (e.g., anti-aging, fine wrinkle improvement, anti-irritation, anti-inflammation, whitening effects, etc.).

In recent years, various plant extracts have been used for the purpose of these cosmetics, and there is an increasing desire for products based on a new concept that shows an improved range of performance characteristics by combining various characteristics.

However, it will be apparent to those skilled in the art to which the present application pertains that these exemplary embodiments are for illustrative purposes only, and are not intended to limit the scope of the present application.

Example 1 preparation of Lactobacillus plantarum CJ L P133 culture

Lactobacillus plantarum CJ L P133 strain deposited under accession number KCTC 11403BP was plated on solid MRS medium (BD Difco, Lactobacillus MRS agar) and cultured at 37 ℃ for about 18 hours after confirmation, pure isolated colonies were collected and inoculated into liquid MRS medium (BD Difco, Lactobacillus broth MRS) using platinum ring and cultured at 37 ℃ for about 18 hours after completion of culture, culture had 1.0 × 10⁹CFU/m L concentration to separate bacterial bodies from the culture, the culture was centrifuged at 4 ℃ and 2500rpm for 20 minutes using a high speed centrifuge (L ABOGENE 1248R.) after filtering the supernatant of the culture, the filtered supernatant was pulverized using a lyophilizer (HETO P L90000). The culture thus prepared was named "Lactobacillus plantarum CJ L P133 culture".

Example 2 confirmation of collagen synthesizing ability of Lactobacillus plantarum CJ L P133 culture

To confirm the collagen synthesis effect of the lactobacillus plantarum CJ L P133 culture prepared in example 1, the amount of collagen expression in skin fibroblasts was measured.

Newborn Human Dermal Fibroblast (NHDF) (5 × 10)⁴Individual cells/dish) were added to Dulbecco modified eagle medium (DMEM, Gibco) containing 10% fetal bovine serum in a 24-well plate and cultured at 37 ℃ for 48 hours for a positive control group, the serum-free DMEM was treated with TGF- β (10ng/m L) and for an experimental group, the MRS medium and lactobacillus plantarum CJ L P133 cultures were treated at concentrations of 0.25mg/m L, 0.5mg/ml and 1.0mg/m L, respectively, and cultured for 48 hours for an experimental group, then, each culture EIA was collected and collagen synthesis ability was measured at 450nm using a spectrophotometer with a PICP a kit (procollagen type I C peptidase immunoassay kit, Takara bioinc.

Specifically, when treated at concentration 3(1.0mg/m L), the amount of collagen expression was increased about 1.6 times in the experimental group treated with the lactobacillus plantarum CJ L P133 culture compared to the experimental group treated with MRS medium, the above-mentioned increase was equal to the result obtained in the positive control group (TGF- β), and thus it was confirmed that the lactobacillus plantarum CJ L P133 culture has excellent collagen synthesis ability for skin fibroblasts, the experimental results are shown in table 1 and fig. 1.

TABLE 1

From the above results, it was confirmed that the culture of lactobacillus plantarum CJ L P133 of the present application can increase the synthesis of collagen, which is known to have a major role in the skin aging mechanism, in which wrinkles are formed by decreasing substrate proteins constituting the skin, or increasing enzymes decomposing the substrate proteins, and thus the culture is effective for improving skin wrinkles.
