Description

Cosmetic composition for improving wrinkles around the eyes {Cosmetic composition for removal the wrinkles at the corners of one´s eyes}

The present invention relates to a cosmetic composition for improving the wrinkles around the eyes.

With the recent development of life sciences, aging research is being approached from many directions and is accelerating.

In particular, the aging that occurs on the skin is easy to observe and has been of much interest.

Representative signs that appear as the skin ages are an increase in wrinkles of the skin, a decrease in elasticity and shine of the skin, a rough skin texture, a yellowing of the skin color, and partial pigmentation.

Such skin aging may be classified into natural aging due to endogenous factors and light aging due to exogenous factors, particularly sunlight. Light aging on the face, nape, back of the hand, etc., which are exposed to a lot of sunlight, causes thickening of the skin, accumulation of denatured elastic fibers,

On the contrary, the skin that is not exposed to sunlight is contracted by the natural aging process, and the function is deteriorated and the thickness of the skin is reduced.

Of the signs that appear as the skin ages, the most noticeable and of interest is wrinkles. It occurs on the face of the forehead, around the eyes, in the forehead, around the mouth, and on the body, such as the head, nape, and hands and feet. It is noticeable before and after 30 years of age, and as it ages, its number, depth, and range increase.

Among the external factors involved in the generation of wrinkles, the influence of ultraviolet rays is as described above, and in addition, stress of the skin due to physical and chemical stimuli may also cause wrinkles. Due to these internal and external factors, the decrease of moisture content of the stratum corneum, thickening of the stratum corneum, epidermal atrophy, degeneration of collagen fibers and elastic fibers of the dermis cause changes in the tertiary structure of the skin, resulting in a decrease in elasticity or elasticity, resulting in wrinkles of the skin. Is formed.

Since the aging of the skin is the accumulation of minute changes that occur over a long period of time, in order to prevent the irritation that the skin is subjected to daily, to protect the skin from the ultraviolet rays that promote aging or the drying of the skin, the skin that decreases with age Steady care and caution, such as supplementing useful ingredients, preventing or eliminating the occurrence of unpleasant ingredients that occur with age, or promoting the blood circulation through massage or cold stimulation. Is needed.

Accordingly, the demand for functional cosmetics that can help skin care is increasing, and recently, products containing active ingredients having an effect of improving wrinkles have been developed.

Looking at the technology related to such a product, the Republic of Korea Patent No. 490212, the 'amino acid complex having an amino acid composition ratio of the stratum corneum and the anti-aging cosmetic composition containing the same', but is known,

In the case of the technology, amino acids are used to show the effects of moisturizing, collagen synthesis enhancement and skin wrinkle improvement, but there is a disadvantage in that the skin is irritated when used due to lack of soothing action.

In addition, as disclosed in the Republic of Korea Patent Publication No. 10-2009-0009054 'the cosmetic composition containing the nano-vesicle vitatox having an antioxidant effect and the improvement of the wrinkles around the eyes,'

In the case of this patent, there is a defect that the wrinkle improvement effect gradually occurs only after 8 weeks after use.

The present invention has been studied in view of all the problems that the conventional cosmetic composition for improving wrinkles around the eyes,

The object of the present invention is to immediately show the effect of wrinkle improvement immediately after use,

After use, the elasticity of the skin increases over a long period of time, fundamentally improving wrinkles,

In use, it is possible to provide a more effective cosmetic composition for improving the wrinkles around the eyes without irritating the skin and having a function of calming the skin.

To this end, the present invention,

By mixing a ratio of medicinal plants with soothing and collagen synthesis, green tea with antioxidant and soothing effects, and extracts of aloe vera, human oligo peptides, which are effective for skin regeneration and elasticity, and natural amino acids ,

Improves moisturizing and elasticity of the skin, providing instant eye wrinkle improvement for a certain period of time without skin irritation, immediately after use, and improving wrinkles around the eyes, which shows excellent skin elasticity after long hours of use or long-term use Characterized in that it can provide a cosmetic composition for.

The cosmetic composition for improving the wrinkles around the eyes of the present invention,

Promotes skin moisturizing and elasticity, provides instant eye wrinkle improvement for a period of time immediately after use, without skin irritation,

Elapsed time after use, or long-term use, there is an effect that fundamentally improve the elasticity and dermal layer of the skin.

Hereinafter, the present invention will be described in detail.

First, the main components of the cosmetic composition for improving the wrinkles around the eyes according to the present invention, Centella, green tea and aloe vera, and human oligo peptide and amino acids added thereto have been found to have the following main ingredients and efficacy.

2. Acquire mixed extract

The mixed raw material is stirred for 48 hours at room temperature in a stirrer to extract a mixed extract.

3. Filtration

The mixed extract was filtered through 250 mesh and 0.5 μm filter paper to obtain a liquid extract.

4. Thickening

The filtered liquid extract was concentrated under reduced pressure at a temperature of 50 ° C. using a rotary pressure reducer to obtain a concentrate of the cosmetic composition of the present invention.

As a result of performing a related test example on the cosmetic composition for improving wrinkles around the eyes according to the present invention, it was found that there is no abnormality in skin safety.

The clinical evaluation was conducted by selecting 11 women over 30 years of age with moderate eyelid wrinkles.

After washing twice a day (morning and evening) for 4 weeks, apply the test product evenly to both eyes and face at the next stage of the skin, and then immediately after using the product and around the eyes after 2 weeks and 4 weeks Was measured.

1. Instant wrinkle improvement

(1) Skin deflection analysis using facial contour image

After 2 minutes of use, the image taken by the digital camera with the contour of the top of the right cheek (moire topography) was analyzed using an image analyzer to measure the degree of change of the deflection of the skin by measuring the changed angle. As a result of analyzing the degree of change in the angle of the contour image, as shown in Table 2, the deflection decreased 3.88% immediately after use.
