Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic having an excellent skin care effect and an effect of restoring the original brightness and transparency of the skin.

[0002]

2. Description of the Related Art Hitherto, blackening of skin due to sunburn has been attributed to the fact that tyrosine present in skin becomes melanin pigment by the action of tyrosinase, and this melanin is excessively produced. In order to prevent or treat this pigmentation, cosmetics comprising a whitening component such as L-ascorbic acid and derivatives thereof, colloidal sulfur, hydrogen peroxide and hydroquinone have been proposed.

[0003]

However, these whitening cosmetics have insufficient storage stability, or do not have a sufficient whitening effect, or lighten dark skin. Although the effect is recognized, the skin care effect is problematic, and it has been difficult to expect the original brightness and transparency of the skin by improving the original function of the skin. Therefore, there is a demand for the development of a cosmetic that is not only effective in preventing or treating pigmentation, but also has an excellent effect of restoring the original brightness and transparency of the skin and has a high skin care effect.

[0004]

Means for Solving the Problems The present inventor has proposed a whitening ingredient,
It has been found that when a lipid and a blood circulation promoting component are combined and combined, not only a whitening effect but also an effect of improving the original brightness and transparency of the skin and a cosmetic having a high skin care effect can be obtained. It has also been found that if the cosmetic is applied after treatment with a lotion containing a water-soluble moisturizing component, these effects are exhibited early.

That is, the present invention provides the following component (A):
(B) and (C): The present invention provides a cosmetic containing (A) lipids, (B) a blood circulation promoting component, and (C) a whitening component. The present invention also provides
After treating the skin with cosmetics containing water-soluble moisturizing ingredients,
A makeup method characterized by applying the above-mentioned cosmetic is provided.

[Evaluation Method] 1) Evaluation of Rough Skin Improving Effect A glass cup (inner diameter: 2 cm) containing acetone / ether (volume ratio: 1: 1) was attached to the inner side of a human forearm, and degreased for 15 minutes. Induced rough skin. After applying a fixed amount of each sample to half the area of the rough skin every morning and evening for 5 days, the effect of improving the rough skin was observed by visual judgment by five specialized panelists. Evaluation criterion 5: Extreme recovery: All five panelists judged that the recovery was remarkable. 4: Recovery: Three or more panelists judged that the recovery was almost complete. 3: Slight recovery: One or two of the panelists were judged to have largely recovered. 2: No recovery: All panelists did not judge that recovery was successful. 1: Deteriorated: One or more of the panelists judged that it was deteriorating.

2) Evaluation of Skin Brightness and Transparency After applying a fixed amount of each sample to the human face for 30 days every morning and evening, the brightness and transparency were evaluated by visual evaluation by five expert panelists.
The effect of improving the transparency was observed. 5: Extreme recovery: All five panelists judged that the recovery was remarkable. 4: Recovery: Three or more panelists judged that the recovery was almost complete. 3: Slight recovery: One or two of the panelists were judged to have largely recovered. 2: No recovery: All panelists did not judge that recovery was successful. 1: Deteriorated: One or more of the panelists judged that it was deteriorating.

3) Transparency The transmittance of the lotion was measured using a spectrophotometer (UV-160) manufactured by Shimadzu Corporation, and the transparency of distilled water used as a control was defined as 100, and the range of 100 to 75 was transparent.
The range of less than 75 to 20 was determined to be translucent.

From Tables 1 to 11, it can be seen that the cosmetics containing the components (A), (B) and (C) are excellent in the effect of improving skin brightness and transparency and also in the effect of improving rough skin. Understand. In addition, the difference between 5 and 4, which are the evaluation criteria of the skin brightness / transparency improvement effect in Tables 1 to 11, was clearly different visually.

Also, 0.2% of succinic acid, 0.3% of sodium hydrogen phosphate, 0.2% of 2- (2-hydroxyethoxy) ethylguanidine succinate, 1% of Yuzu extract, 0.2% of Altea extract %, Chamomile extract 0.3%, glycerin 5%, xanthan gum 0.2%, denatured alcohol 0.2%, methyl paraoxybenzoate 0.2%, polyoxyethylene isocetyl ether (20E.O.) 1% And after taking a lotion containing a balanced amount of water on cotton and applying it by wiping the skin, the above Tables 1 to 11
When the cosmetic was applied, the effect of improving skin brightness and transparency was obtained earlier.

[0045]

By using the cosmetic of the present invention, not only whiteness but also the original brightness and transparency of the skin can be imparted to the skin, and an excellent skin care effect can be obtained.
