Description

The present invention relates to cosmetological methods and skin cosmetic kits.

Conventionally, a cosmetic containing pectin has been known as a cosmetic that gives a user freshness at the time of application (Patent Document 1).

JP-A-2002-047128

However, although the cosmetic of Patent Document 1 can obtain freshness at the time of application, it has been found that the moisturizing sensation (sustainability of the moisturizing sensation) over time after application is not always sufficient. This is because the cosmetic of Patent Document 1 contains pectin and a salt that produces polyvalent cations in an aqueous solution in one preparation, so that the agent gels and a uniform film is not formed on the skin. Presumed to be due.

An object of the present invention is to provide a beauty method that prevents the evaporation of water on the skin over time and has an excellent moisturizing feeling. A further object of the present invention is to provide a skin cosmetic kit that prevents the evaporation of water on the skin over time and imparts an excellent moisturizing feeling.

The present invention
[1] A beauty method comprising a step of applying either one of cosmetic A containing pectin and cosmetic B containing a polyvalent organic salt to an area to be applied on the skin and then applying the other to the area to be applied. ,
[2] A cosmetic containing pectin, which is used in the beauty method according to the above [1].
[3] Cosmetics containing a polyvalent organic salt, which are used in the beauty method described in [2] above, and [4] Cosmetics containing pectin A and cosmetics containing a polyvalent organic salt. The present invention relates to a skin cosmetic kit including a charge B.

According to the present invention, it is possible to provide a beauty method that prevents the evaporation of water on the skin over time and has an excellent moisturizing feeling. Further, according to the present invention, it is possible to provide a skin cosmetic kit that prevents the evaporation of water on the skin over time and imparts an excellent moisturizing feeling.

In the beauty method of the present invention, one of cosmetic A containing pectin and cosmetic B containing a polyvalent organic salt is applied to the skin to be coated, and then the other is overcoated on the skin to be coated. Including.

The cosmetological method of the present invention can prevent the evaporation of water on the skin over time, so that an excellent moisturizing effect is achieved. This mechanism is presumed to be as follows.
By applying the cosmetic A on the skin, a hydrophilic film containing pectin is formed on the skin. It is presumed that the pectin in the film is crosslinked to form a uniform hydrophobic film by overcoating the film with cosmetic B containing a polyvalent organic salt such as starch aluminum octenyl succinate. As a result, the effect of preventing water transpiration is exhibited. The same applies to the case where the cosmetic B is first applied on the skin and then the cosmetic A is repeatedly applied.
In particular, when starch aluminum octenyl succinate is used as the polyvalent organic salt, the hydrophobic film formed has a polymer chain of starch aluminum octenyl succinate incorporated into the film, resulting in the flexibility of the film. It is preferable because it improves and provides a film with an excellent feel without a feeling of tightness.
On the other hand, when the pectin and the polyvalent organic salt are mixed to form a single preparation without recoating the cosmetic A and the cosmetic B, the pectin is crosslinked in the above preparation, and therefore after the application. Since it is difficult to form a uniform film on the skin, a sufficient effect of preventing water evaporation is not exhibited.

In the present invention, the mode in which each cosmetic is repeatedly applied to the skin, for example, the application means, the application interval of each cosmetic, the application order, and the like are not limited. For example, the cosmetic A may be applied to the skin to be applied and then the cosmetic B may be repeatedly applied to the skin to be applied, or the cosmetic B may be applied to the skin to be applied and then the cosmetic A is applied. May be overcoated on the site to be coated. Further, the present invention also includes a mode in which a cosmetic different from the cosmetics A and B is used in combination, and a mode in which the cosmetics A and B are repeatedly applied a plurality of times.

The interval between application of each cosmetic is not particularly limited, but it is preferable that cosmetic A and cosmetic B are applied continuously. For example, after applying one cosmetic to the skin to be applied, the other. The interval until the cosmetic is repeatedly applied to the application site is, for example, preferably 10 minutes or less (that is, 0 to 10 minutes), and more preferably 2 minutes or less. Since it is a recoating, it is necessary to apply one of the cosmetics to the portion to be applied on the skin and then apply the other cosmetic to the portion to be applied without washing off the cosmetic.

The beauty method of the present invention can be performed not only personally and at home, but also as a commercial service in an aesthetic salon or the like. Furthermore, the cosmetological methods of the present invention are not used for methods of surgery, treatment or diagnosis of humans.

The site to which the beauty method of the present invention is applied is not particularly limited as long as it is skin, and the face (for example, forehead, eyes, eyes, cheeks, mouth, etc.), arms, elbows, back of hands, fingertips, feet, knees, and heels. , Neck, armpits, back, etc. The face is particularly preferable.
