Description

A COSMETIC COMPOSITION HAVING EXCELLENT EFFECT OF IMPROVING SKIN TONE, TEXTURE, BLEMISH, LUSTER AND ELASTICITY}

The present invention relates to a cosmetic composition excellent in improving skin tone, skin texture, melasma, blemishes, gloss and elasticity.

Skin is the largest tissue of the human body, which occupies the outermost part of the body, and plays an important role as an epithelial tissue that protects various organs, muscles, and bones in the body from the outside. In addition, the skin has functions such as regulation of body temperature, sensory function, and vitamin D synthesis.

The skin is composed of several layers, largely composed of the epidermis, dermis, and subcutaneous fat. Among them, the epidermal layer is composed of a basal layer, a sebaceous layer, a granular layer, a transparent layer, and a stratum corneum from the bottom. The basal layer is in contact with the dermal layer below it, and consists of melanin-producing cells and keratinocytes, which mainly determine skin color, in a ratio of about 1:10, and each melanocyte is in contact with an average of 36 keratinocytes. The number of melanocytes is constant regardless of ethnicity and skin color, but is determined by the number of melanosomes, size, degree of melanization, distribution of melanosomes, and degradation of melanosomes within keratinocytes.

The dermis accounts for 90% of the skin. Collagen fibers and elastic fibers are woven in a net shape to support the skin, and between cells and fibers, moisture, protein, and sugar mineral salts, called matrix, are in a jelly state, providing skin nutrition and It is involved in metabolism and water retention.

On the other hand, the generation of active oxygen in the living body skin is generated through various pathways, and is generated by 2 to 3% of respired oxygen, ultraviolet rays, cigarette smoke, air pollution, and the like. The generated active oxygen reacts with the unsaturated fatty acid of the cell membrane to form a new radical, the peroxide radical, and causes a chain reaction to lead to lipid peroxidation. Lipid peroxidation reduces the liquidity of the cell membrane and increases the permeability of the cell membrane. These reactive oxygen species increase collagenase (MMP) in the dermis, destroy matrix protein structures, and reduce fibroblast function, resulting in loss of skin elasticity.

Background art related to the present invention is disclosed in Korean Patent Publication No. 2001-0107964 (published on December 7, 2001, title of the invention: oil-in-water emulsion containing an ascorbic acid compound).

Hereinafter, the components of the cosmetic composition will be described in more detail.

Ascorbic Acid

The ascorbic acid is called vitamin C, and is the most powerful antioxidant among superoxidative vitamins in cells, and acts to remove free radicals and restore DNA damaged by free radicals. Acos big acid is a representative water-soluble antioxidant, maintains collagen synthesis and elasticity in relation to skin aging, and plays an important role in skin whitening. In addition, it has a function of protecting the skin from environmental external factors and photoaging that can cause skin damage.

By applying the ingredients and contents described in Tables 1 and 2 below, a cosmetic composition of an essence formulation was prepared in a conventional manner. Specifically, the ascorbic acid in Tables 1 and 2 below is synthetically prepared by esterification of 2-KGA (2-Keto-L-Gulonic Acid), and the resulting MeKGA (2-Keto-L-Gulonic Acid Methyl Ester) is rearranged to produce ascorbic acid. Tocopherol was prepared synthetically by condensation of trimethylhydroquinone and isophytol. The product purified by vacuum distillation was used. Ferulic acid is the final product obtained by mixing vanillin, malonic acid, ethanol solvent and pyridine as starting materials, stirring, cooling crystallization, filtering, bleaching, and recrystallization after centrifugation. was used. Troxerutin was hydroxyethylated by ethylene oxide using rutin and water as starting materials to prepare a first compound. Then, a product crystallized by filtering the first compound and adding isopropyl alcohol was used.

Test Example 1: Evaluation of skin irritation

In the case of using the cosmetic compositions of Examples 1 to 5 and Comparative Examples 1 to 6, a skin patch test was conducted to investigate skin irritation test. For the blood test, adult females between the ages of 19 and 59 were selected as those without skin disease on the test site, and a skin patch test was conducted on a total of 31 test subjects. After wiping the patched area, such as the back, with 70% ethanol and drying it, 25 μl of the cosmetic compositions of the above Examples and Comparative Examples were added and applied for 24 hours, the patch was removed, the skin reaction was examined within 1 hour, and the next day (48 hours after the start of the patch) was examined again. The skin half was judged according to the following test criteria. The skin patch test results are shown in Table 3 below.

* Skin reaction test criteria

-: No reaction +: Weak positive reaction (erythema) ++: Positive reaction (erythema) +++: Strong positive reaction (erythema, edema) ++++: Severe positive reaction (erythema, edema, blisters)

Referring to the results of Table 3, in the case of the cosmetic compositions of Examples 1 to 5 of the present invention, it was found that there was little skin irritation compared to Comparative Examples 1 to 6.

At this time, the degree of separation and discoloration of the product was classified into the following 6 grades and evaluated.

* Criteria for separation and discoloration evaluation

0: No change 1: Slight separation (discoloration) 2: Slight separation (discoloration) 3: Slight separation (discoloration) 4: Severe separation (discoloration) 5: Extreme separation (discoloration)

Referring to the results of Table 4, it can be seen that Examples 1 to 5 of the present invention have excellent formulation stability with less separation and discoloration than Comparative Examples 1 to 6 outside the configuration of the present invention.

Test Example 3: Skin tone improvement effect

For the cosmetic compositions of Examples 1 to 5 and Comparative Examples 1 to 6, changes in skin tone were measured for Example 1 as a representative example. Specifically, 20 female clinical groups between the ages of 20 and 59 were conducted. The skin conditions of the 20 subjects who participated in the evaluation experiment were 12 dry skin, 4 normal dry skin, 2 normal skin, 1 combination skin, and 1 normal skin. , there were no test subjects with drug side effects, light sensitivity, and atopic disease experiences.

For instrumental skin measurement, the test subjects were allowed to adjust to the measurement environment by resting their skin for about 30 minutes in a space under constant temperature and humidity conditions (temperature 20 ~ 24 ℃, humidity 40 ~ 60%) after washing their face with the prepared cleanser. Using the Janus 1 Mark II, which can photograph the entire face of the test subject, the entire face was photographed before using the test product, 2 weeks after using the product, and 4 weeks after using the product. Among the pictures taken, a specific area of the general light mode image was designated and the degree of skin tone was analyzed.
