Description

  The present invention relates to a skin care method, and more specifically, by sequentially applying a liquid lipophilic cosmetic mainly containing polar oil and a gel or solid lipophilic cosmetic containing a specific nonpolar oil to the skin, The present invention relates to a skin care method capable of giving an excellent elasticity and maintaining the effect for a long time.

  Skin care cosmetics intended to give a feeling of elasticity because the skin is soft and elastic and gives a youthful impression, but the skin is lost due to aging and drying of the skin. Various proposals have been made.

  For example, cosmetics containing coenzyme Q, a toki extract, and the like and improving the skin condition have been disclosed (Patent Documents 1 and 2).

  On the other hand, cosmetics that give a firm feeling by forming a film on the skin instead of using such medicinal ingredients have also been proposed. For example, a water-in-oil emulsion composition containing glyceryl isostearate and polyvinyl alcohol Products (Patent Document 3), compositions for external use (Patent Document 4) in which oily particles having a particle diameter of 10 to 2000 μm are dispersed in an aqueous phase containing polyvinyl alcohol, skin cosmetics containing agar and specific silicone oil ( Patent document 5) etc. are disclosed. These are intended to give a feeling of elasticity by forming a film on the skin to prevent the evaporation of moisture, but the effect is not sufficient and lacks sustainability.

  Further, an oil-in-water emulsified cosmetic (Patent Document 6) using stearyl stearate and a hydrocarbon wax is also disclosed. However, in such an oil-in-water emulsified cosmetic, since the film made of hydrocarbon wax is not continuous, the film is not sufficiently occluded and the action of pulling and tightening the skin is not satisfactory, and a satisfactory elasticity Was not obtained. On the other hand, when trying to form a continuous film with a hydrocarbon wax, its extensibility is low and it is difficult to uniformly apply it to the skin, so it must be a dosage form such as an oil-in-water emulsified cosmetic. There was no actual situation.

  It is used in the present invention by emulsifying and mixing the above components (B), (C), (E), (F) and other optional components such as components (D), (A ′) as necessary according to a conventional method. Gel-like or solid water-in-oil emulsified cosmetics can be prepared. This gel or solid water-in-oil emulsion type cosmetic may be gel or solid at room temperature (20 ° C.), and when the following penetration is measured at 20 ° C., the value is 5 or more. , Preferably in the range of 40-300. The penetration is measured using a rheometer (manufactured by Fudo Kogyo Co., Ltd.) with a measurement temperature of 20 ° C., a range of 500 g, and a 5 mm Φ adapter, with a penetration of 2 mm at a speed of 6 cm / min.

  The skin care method of the present invention is carried out by combining the liquid lipophilic cosmetic prepared as described above and the gel or solid lipophilic cosmetic. First, an appropriate amount of liquid lipophilic cosmetic is applied onto the skin such as the face. Next, a gel-like or solid lipophilic cosmetic is applied on the applied part. The application amount of the liquid lipophilic cosmetic and the gel or solid lipophilic cosmetic is not particularly limited, and varies depending on the use site, but both are preferably 0.3 to 10 g, and more preferably 0.5 to 3 g. Moreover, you may wipe off the excess amount after apply | coating with gauze etc. The interval between the application of the liquid lipophilic cosmetic and the gel or solid lipophilic cosmetic is preferably within about 5 minutes. By sequentially applying the liquid lipophilic cosmetic material and the gel or solid lipophilic cosmetic material in this manner, an excellent elasticity can be obtained and the effect can be maintained for a long time. It seems like.

  That is, when a liquid lipophilic cosmetic is first applied on the skin, the component (A) polar oil imparts flexibility and smoothness to the skin and a coating film is formed. When a gel or solid lipophilic cosmetic is applied on top of it, (B) a hydrocarbon wax, which is a nonpolar oil, and (C) a hydrogenated polyisobutene having a number average molecular weight of 1000 to 3000 are mutually moderately mixed with a polar oil. Therefore, it is possible to form a continuous and uniform film while uniformly spreading on the polar oil coating film. Since the film formed on the skin in this manner has a high blocking property, it prevents moisture from transpiration, and is highly elastic and strong, so that it effectively pulls and tightens the skin. As a result, an excellent elasticity can be obtained and the effect can be maintained for a long time.
