Description

The present invention improves the firmness of the skin, including the step of massaging while applying a cosmetic containing a touki extract, a roman chamomile extract, a shakyaku extract, a chow extract, and a white vana lupine extract to the face. Regarding beauty methods (excluding medical treatment).

When the skin is soft and elastic and has elasticity, it gives a youthful impression, but since the elasticity is lost due to aging, dry skin, etc., the purpose is to give a feeling of elasticity and luster. Various cosmetics have been proposed.

For example, cosmetics that give a firm feeling by forming a film on the skin have been proposed, such as a water-in-oil emulsified composition containing glycerin isostearate and polyvinyl alcohol (Patent Document 1), and a particle size of 10. An external composition (Patent Document 2) in which oily particles of ~ 2000 μm are dispersed in an aqueous phase containing polyvinyl alcohol, a skin cosmetic containing agar and a specific silicone oil (Patent Document 3), and the like are disclosed. These are intended to give a firm feeling by forming a film on the skin to prevent the evaporation of water, but the effect is not sufficient.

In addition, as cosmetics that give firmness, cosmetics that give firmness and luster to the skin in combination with specific plant-derived ingredients and other medicinal ingredients (see, for example, Patent Documents 4 to 7), and highly polymerized silicone oils. (For example, refer to Patent Document 8) is disclosed as a cosmetic containing the above-mentioned ingredients to give elasticity and luster.
However, no cosmetic has been obtained that sufficiently exerts the effect of improving firmness in any of the cosmetics.

Place an appropriate amount of cosmetics on the center of the forehead, cheeks, and chin.
(1) Using the pad of the index finger, middle finger, and ring finger, starting from the position of the cosmetic placed on the cheek, spread it in a circle from below toward the temple. Then use the same finger to move your finger sideways so that it is lightly pressed from the side of the nose to the outside.
(2) Using the pad of the index finger, middle finger, and ring finger to start from the position of the placed cosmetic on the chin, spread it in a circle from below toward the parotid gland. Then use the same finger to move your finger sideways so that it is lightly pressed outward from the center of the chin.
(3) Forehead, nose, eyebrows, eyes Starting from the position of the placed cosmetics, use the pad of the index finger, middle finger, and ring finger to spread while drawing a circle. Then, using the same finger, move the finger sideways so that it is lightly pressed outward from the center of the forehead. Spread it on the upper surface of the nose, the side of the nose, and the lower part of the nose. After that, move your fingers from the inside of the eyebrows to the outside of the eyebrows, gently pressing the eyelids and eyes from the center of the face toward both ends.

It was mixed so as to be 2600 parts by mass to obtain a collagen mixture.

Cosmetics were prepared by a conventional method using the cosmetic formulations shown in Table 1.

[Usage test]
A use test was carried out using the cosmetics shown in Table 1.
The subjects were 17 women aged 40 to 55 years (average age 47.2 years), and the cosmetics were applied to the face twice a day. Before and after 4 weeks of use, skin elasticity (tension) and keratin moisture The amount and the amount of transepidermal water evaporation were measured. Regarding the method of use, 6 out of 17 subjects instructed to massage while applying during use, and 11 subjects only instructed to apply.

[Measuring method]
(1) Acclimation The subject cleansed the face, washed the face, and then acclimatized the subject in a room adjusted at a temperature of 20 to 22 ° C. and a humidity of 45 to 55% for 15 minutes to adjust the initial conditions and perform measurement.

(2) Skin elasticity (tension)
<Skin elasticity evaluation>
Skin elasticity was measured using a probe with a Cutometer diameter of 2 mm or 4 mm of a multi-probe type skin measuring instrument (Cutometer DUAL MPA580). Specifically, two points on the cheek were measured, and the obtained Uf value and Ur value were used to calculate the average value of the results obtained by the following formula. The result of using a probe having a diameter of 2 mm was defined as the epidermis firmness value, and the result of using a probe having a diameter of 4 mm was defined as the dermis firmness value.
Hari = Ur / Uf
Uf: Final extensibility (total displacement after 5 seconds)
Ur: Return extensibility (displacement amount recovered immediately after decompression and release)

(3) Amount of keratin water 5 points on the cheek were measured using SKICON-200EX, and the average value was taken as the amount of keratin water.

(4) Transepidermal water loss amount Two points on the cheek were measured using a Vapometer, and the average value was taken as the transepidermal water loss amount.

As shown in FIG. 1, the beauty method of performing massage while applying the cosmetic of the present invention markedly increased the amount of keratin water as compared with the method of simply applying.

As shown in FIG. 2, the beauty method of performing massage while applying the cosmetic of the present invention may reduce the amount of transepidermal water loss and improve the condition of the epidermis as compared with the method of simply applying. Admitted.

As shown in FIG. 3, the beauty method of performing massage while applying the cosmetic of the present invention increased the firmness value of the epidermis and improved the firmness of the epidermis as compared with the method of simply applying the cosmetic.

As shown in FIG. 4, the cosmetological method of performing massage while applying the cosmetic of the present invention increased the firmness value of the dermis and improved the firmness of the dermis as compared with the method of simply applying the cosmetic.
