Description

美容方法beauty method
　本発明は、美容方法に関する。 The present invention relates to a beauty method.
　紫外線には、紫外線Ａ波（ＵＶ－Ａ、３１５～４００ｎｍ）及び紫外線Ｂ波（ＵＶ－Ｂ、２８０～３１５ｎｍ）等が知られている。このうち、ＵＶ－Ａは、日焼けは引き起こしにくいが、近年の研究では、シミやしわの発生に大きく関わっていることが分かって来た。また、ＵＶ－Ｂは波長が短く、ＵＶ－Ａに比べるとオゾン層や雲に阻まれ、地上に到達する量は全紫外線量の約１０％と少量ではある。しかしＵＶ－Ｂはエネルギーが強く、肌表面の細胞を傷つけたり、炎症を起こしたりするため、皮膚ガンやシミの原因になることもあると知られている。 Ultraviolet rays are known to include ultraviolet A waves (UV-A, 315-400 nm) and ultraviolet B waves (UV-B, 280-315 nm). Of these, UV-A is less likely to cause sunburn, but recent studies have shown that UV-A is greatly involved in the generation of spots and wrinkles. In addition, UV-B has a short wavelength and is blocked by the ozone layer and clouds compared to UV-A, and the amount that reaches the ground is only about 10% of the total amount of ultraviolet rays, which is a small amount. However, UV-B has a high energy and is known to cause skin cancer and blemishes because it damages the cells on the skin surface and causes inflammation.
　このように皮膚に及ぼす紫外線の影響が明らかになるにつれて、様々な紫外線吸収剤を含むスキンケア用組成物が提案されている。 As the effects of ultraviolet rays on the skin have become clearer, skin care compositions containing various ultraviolet absorbers have been proposed.
　例えば、特許文献１では、（Ａ）カルボシロキサンデンドリマー構造を側鎖に有するビニル系ポリマーと、（Ｂ）紫外線吸収剤および紫外線散乱剤からなる群より選択される少なくとも１種と、（Ｃ）アニオン界面活性剤および非イオン性界面活性剤からなる群より選択される少なくとも１種とを含有する外用組成物が開示されている。 For example, in Patent Document 1, (A) a vinyl-based polymer having a carbosiloxane dendrimer structure in a side chain, (B) at least one selected from the group consisting of an ultraviolet absorber and an ultraviolet scattering agent, and (C) an anion A topical composition containing at least one selected from the group consisting of surfactants and nonionic surfactants is disclosed.
　また、特許文献２では、特定の構造を有するピリミジン誘導体（１）又はその塩を主成分とする紫外線吸収剤を含有する皮膚外用剤が開示されている。 In addition, Patent Document 2 discloses an external preparation for skin containing an ultraviolet absorber whose main component is a pyrimidine derivative (1) having a specific structure or a salt thereof.

　しかしながら、紫外線吸収剤を含むスキンケア用組成物による紫外線防止効果は、その後のメーキャップ等によって、すなわち、皮膚をスポンジ、手、ブラシ等で擦過する行為によって、落ちてしまうことがある。 However, the UV protection effect of a skin care composition containing a UV absorber may be lost by subsequent makeup, that is, by rubbing the skin with a sponge, hand, brush, or the like.
　本発明は、上記の事情を改善しようとするものであり、その目的は、紫外線吸収剤を含むスキンケア用品の皮膚へ適用した後でメーキャップ等を行う場合にも、紫外線吸収剤による紫外線吸収の効果を維持することができる美容方法を提供することである。 The present invention is intended to improve the above circumstances, and the object thereof is to achieve the effect of ultraviolet absorption by the ultraviolet absorber even when applying makeup etc. after applying the skin care product containing the ultraviolet absorber to the skin.

The skin on the inside of the subject's arm was washed with soap and 15 minutes later the sample was applied at 2 mg/cm 2 . Then, a titanium electrode was applied to the skin to which the sample had been applied for 10 seconds at 25° C. with heating (Example 1) and without heating (Comparative Example 1).
　より具体的には、実施例１では、４２℃±０．５℃で加熱された電極を用いた。また、比較例１では、加熱されていない電極を用いた。 More specifically, in Example 1, electrodes heated at 42°C ± 0.5°C were used. Also, in Comparative Example 1, an electrode that was not heated was used.
　また、サンプルとしては、濃度１００質量％のメトキシケイヒ酸エチルヘキシル（紫外線吸収剤）を用いた。 Also, as a sample, ethylhexyl methoxycinnamate (ultraviolet absorber) with a concentration of 100% by mass was used.
　そして、実施例１及び比較例１の電極適用後の皮膚の角層を、クリニカル＆ダーム社製の角質チェッカーを用いて、５回剥離し、剥離１回目を１層目の角質試験片とし、剥離２回目を２層目の角質試験片とし、合計各５層目までの角質試験片を作成した。 Then, the stratum corneum of the skin after application of the electrodes of Example 1 and Comparative Example 1 was peeled off five times using a stratum corneum checker manufactured by Clinical & Derm Co., and the first peeling was used as the stratum corneum test piece of the first layer, The second peeling was used as the keratin test piece of the second layer, and a total of 5 layers of keratin test pieces were prepared.
　（吸光度測定）

　得られた吸光度のうち、３４０ｎｍ（図１に示す）及び３６０ｎｍ（図２に示す）における吸光度で、温熱有り（実施例１）と温熱無し（比較例１）のそれぞれの剥離された角質層を比較した。 Among the obtained absorbances, the absorbances at 340 nm (shown in FIG. 1) and 360 nm (shown in FIG. 2) were measured for the exfoliated stratum corneum with heat (Example 1) and without heat (Comparative Example 1). compared.
　図１及び図２から明らかであるように、実施例１（温熱有り）の角質試験片の吸光度は、全体として、比較例１（温熱無し）の場合よりも高いことが分かった。すなわち、本発明の美容方法によって、紫外線吸収剤は皮膚の角質層に導入され、特に、角質層の１層目により多く導入されたことが分かった。この結果からは、本発明の美容方法によって、紫外線吸収剤を含むスキンケア用品の皮膚へ適用した後でメーキャップを行う場合にも、紫外線吸収剤による紫外線吸収の効果を維持できることが示唆された。 As is clear from FIGS. 1 and 2, the absorbance of the keratin test piece of Example 1 (with heat) was found to be higher than that of Comparative Example 1 (without heat). That is, it was found that the ultraviolet absorber was introduced into the stratum corneum of the skin by the cosmetic method of the present invention, and in particular, a large amount was introduced into the first layer of the stratum corneum. These results suggest that the cosmetic method of the present invention can maintain the effect of UV absorption by the UV absorber even when makeup is applied after skin care products containing UV absorbers are applied to the skin.
　《実施例２及び比較例２》

　図３及び図４から明らかであるように、実施例２（温熱有り）の角質試験片の吸光度は、全体として、比較例２（温熱無し）の場合よりも高いことが分かった。すなわち、本発明の美容方法によって、紫外線吸収剤は皮膚の角質層に導入され、特に、角質層の１層目により多く導入されたことが分かった。この結果からは、本発明の美容方法によって、紫外線吸収剤を含むスキンケア用品の皮膚へ適用した後でメーキャップを行う場合にも、紫外線吸収剤による紫外線吸収の効果を維持できることが示唆された。 As is clear from FIGS. 3 and 4, the absorbance of the keratin test piece of Example 2 (with heat) was found to be higher than that of Comparative Example 2 (without heat). That is, it was found that the ultraviolet absorber was introduced into the stratum corneum of the skin by the cosmetic method of the present invention, and in particular, a large amount was introduced into the first layer of the stratum corneum. These results suggest that the cosmetic method of the present invention can maintain the effect of UV absorption by the UV absorber even when makeup is applied after skin care products containing UV absorbers are applied to the skin.
