Description

Cosmetic composition that provides skin tone-up and dead skin cell removal effects and method for manufacturing the same {Cosmetic composition that provides skin tone-up and dead skin cell removal effects and method for manufacturing the same}

The examples below relate to a cosmetic composition that provides skin tone-up and dead skin cell removal effects and a method of manufacturing the same.

The skin is a part that surrounds the entire body and plays a role in protecting the living body from various external stimuli, obstacles, or dryness. From the outside, the skin is largely divided into three layers: the epidermis, dermis, and subcutaneous tissue. The epidermis is further classified into the stratum corneum, stratum granulosum, stratum spinosum, and basal layer. Among these, the stratum corneum is the outermost layer of the epidermis and is where cosmetics come into direct contact. It has physical and chemical resistance and is very related to the cosmetic properties of the face.

The differentiation process of epidermal cells is called keratinization. Through the keratinization process, cells pass through the basal layer, spinous layer, granular layer, and stratum corneum, and repeat the process of shedding into old keratinocytes in the outermost layer. The cells that arrive at the stratum corneum become keratin (dead skin cells), which are flat, dead cells. Every day, millions of dead keratin cells fall off the skin and are replaced with new keratin cells.

However, if this keratinization process is not smooth, abnormal keratinocytes are produced and accumulated on the skin surface, thickening the stratum corneum, roughening the skin, and making the skin dull, making it difficult to apply makeup or making it look lifeless.

Accordingly, the present inventors conducted research on a cosmetic composition that not only has an excellent exfoliation effect but also has a skin tone improvement effect and can simultaneously provide moisturizing and soothing effects to skin that can become dry and sensitive due to exfoliation. As a result, the present invention was completed.

[Experimental Example 1] Evaluation of exfoliation effect and skin tone improvement effect

The exfoliation effect and skin tone improvement effect of the prepared Examples and Comparative Examples 1 to 4 were evaluated by the following methods.

Evaluation of exfoliation effect

Specifically, subjects in their 20s or 30s were divided into 5 groups of 20 people, and the compositions of Examples and Comparative Examples 1 to 4 were applied to the face once a day. Before application, immediately after application, and 2 weeks later, the compositions were applied to the cheeks of the subjects' faces. The dead skin cells of the area were collected using corneofix, a special adhesive tape, and photographed with a Visioscan VC98. For the subject's skin, the average desquamation index (D.I) was analyzed, and the results are shown in Table 2 below. The unit of the measured skin keratin value is %, and the DI% and the degree of skin keratin are proportional. In addition, the skin keratin change rate below is a value expressed as a percentage of the degree of change (measured value after application - measured value after application) based on the value measured before application.

Evaluation of skin tone improvement effect

In the evaluation of the exfoliation effect, the cosmetic compositions of Examples and Comparative Examples 1 to 4 were applied to the entire face twice a day for 4 weeks to each of the 5 groups. After 4 weeks, a chromameter (Minolta CM-3500d) was used. The degree of skin tone improvement was evaluated by measuring the change in color brightness (△L), and the results are shown in Table 3 below. The values shown in Table 3 below are the average values for each group.

Degree of skin tone improvement (△L) Example 4.5 Comparative Example 1 0.8 Comparative Example 2 3.8 Comparative Example 3 1.2 Comparative Example 4 3.5

As shown in Tables 2 and 3, the composition of the example contains both lactic acid and glycolic acid, and in particular, is applied by including 0.3 to 7.5% by weight of lactic acid and 0.1 to 2.5% by weight of glycolic acid based on the total weight of the composition. It had an excellent exfoliating effect not only immediately after application but also two weeks after application, and the skin tone improvement effect was very excellent. On the other hand, Comparative Example 1, which did not contain lactic acid and glycolic acid, and Comparative Example 3, which contained trace amounts of lactic acid and glycolic acid, had very little exfoliation effect as well as skin tone improvement effect.

Therefore, it was found that an excellent exfoliation effect and skin tone improvement effect were achieved when 0.3 to 7.5% by weight of lactic acid and 0.1 to 2.5% by weight of glycolic acid were included based on the total weight of the composition.

[Experimental Example 2] Evaluation of feeling of use

The cosmetic compositions of the Examples and Comparative Examples 1 to 4 were applied to the entire face of the five groups of Experimental Example 1 twice a day for 4 weeks to determine the feeling of use of the prepared Examples and Comparative Examples 1 to 4. Then, through a survey, each of the exfoliating effect, skin tone improving effect, moisturizing effect, and skin soothing effect was rated on a 5-point scale (very low exfoliating effect, skin tone improving effect, moisturizing effect, or skin soothing effect: 1 point) , low: 2 points, normal: 3 points, high: 4 points, very high: 5 points) and the average value was calculated, and the results are shown in Table 4 below.

As shown in Table 4, in the case of the composition of the example containing 0.3 to 7.5% by weight of lactic acid and 0.1 to 2.5% by weight of glycolic acid based on the total weight of the composition, the exfoliation effect and skin tone improvement effect felt by the user All were excellent, and the moisturizing and skin soothing effects were also excellent. On the other hand, Comparative Example 1, which did not contain lactic acid and glycolic acid, and Comparative Example 3, which contained trace amounts of lactic acid and glycolic acid, had very little exfoliation effect and skin tone improvement effect felt by the user, similar to the results of Experiment 1 above. . In addition, Comparative Example 2, which did not contain plant extracts even though it contained lactic acid and glycolic acid, had an excellent exfoliation effect and skin tone improvement effect, but had a poor moisturizing effect and skin soothing effect, leaving the skin feeling tight and dry after use. In Comparative Example 4, since it contained more lactic acid and glycolic acid than the Example, the moisturizing effect and skin soothing effect were poor compared to the Example, and the exfoliation effect and skin tone improvement effect were also poor compared to the Example.

Through this, the cosmetic composition according to one aspect of the present invention contains 0.02 to 0.5% by weight of betaine, 0.03 to 0.75% by weight of butylene glycol, 0.24 to 6% by weight of cetrimonium chloride, and 0.6% by weight based on the total weight of the composition. It has an excellent exfoliating effect and skin tone improvement effect by containing as active ingredients 15 to 15% by weight of cellulose, 0.3 to 7.5% by weight of lactic acid, 0.1 to 2.5% by weight of glycolic acid, and 0.034 to 0.85% by weight of plant extract. At the same time, it was found that it can provide moisturizing and skin soothing effects to skin that may become dry due to exfoliation, resulting in an excellent feeling of use.
