Definitions
- the present invention relates to a technique for improving vascular function by applying high-frequency electrical stimulation, for example, a beauty method.
- a high frequency beauty method is known that can improve wrinkles and sagging of the skin by passing a high frequency (RF) current to the skin such as the face and limbs.
- RF high frequency
- a high-frequency current is applied to the skin, the temperature of the dermis layer and subcutaneous tissue rises. It is expected that the heating action promotes the flow of blood and promotes the regeneration of collagen in the dermis layer by causing heat damage to the collagen in the dermis layer.
- various beauty treatment devices using such high frequencies have been proposed (for example, Patent Document 1).
- Patent Document 1 Japanese Unexamined Patent Publication No. 2018-489

With increasing awareness of health in recent years, more fundamental improvement of function at the constitutional level is desired.
- One of the objects of the present invention is to provide a cosmetic method based on the improvement of vascular function obtained by applying high frequency to the skin.
- a cosmetological method comprising applying high frequency to the skin to enhance gene expression of a vascular structure stabilizing factor.

- a high frequency voltage that enhances the gene expression of the vascular structure stabilizing factor is applied to the pair of electrodes.
- the high frequency voltage is applied with the pair of electrodes in contact with the skin.
- applying high frequency and “applying high frequency” mean applying a high frequency voltage to an object by applying a high frequency voltage between a pair of electrodes arranged in contact with the object at intervals. It means that a high frequency current is passed.
- the word "about” used to indicate a numerical value means that it includes a numerical value of 5% before and after the numerical value modified by this word.
- a cosmetological effect can be brought about by improving the vascular function.
- a cosmetic method comprises applying a high frequency to the skin to enhance gene expression of a vascular structure stabilizing factor.
- a vascular structure stabilizing factor By enhancing the gene expression of the vascular structure stabilizing factor, the vascular structure is stabilized (for example, the thickness of the blood vessel becomes thicker), and a strong blood vessel can be created. Since strong blood vessels contribute to the tension of the skin, it can be said that the application of RF current to the skin contributes to the tension of the skin.
- the frequency of the high frequency applied to the skin is in the range of 0.5 MHz to 4 MHz, for example, 0.5 MHZ, 1 MHz, 2 MHZ, 3 MHz or 4 MHz, or the range defined by any of the above frequencies (eg, for example. Any frequency included in the range of 1 to 4 MHz) may be used. In some embodiments of the invention, the frequency is about 1 MHz.
- VE-Cadherin and Integrin ⁇ 5 are known as vascular structure stabilizing factors.

- This resistance value changes depending on the condition of the user's skin and the type of external skin preparation such as lotion applied to the skin. For example, it is known that when a high-frequency current is applied to the skin of a human body, the skin generates heat and the impedance inside the skin decreases as the temperature of the skin rises. Therefore, as the temperature of the skin rises, the current flowing between the first electrode 10a and the second electrode 10b increases, and the measured resistance value decreases.

Next, the first electrode and the second electrode were placed in contact with the culture solution of the vascular endothelial cells in the culture vessel and at intervals from each other.

実験1では、図1に示した構成において、第1電極および第2電極をそれぞれリード線によって制御回路に接続し、第1電極および第2電極を任意の位置に配置できるようにした高周波装置を用い、以下のようにして、血管内皮細胞(HUVEC)に対して高周波を適用した。まず、第1電極を底部に配置した培養容器(シャーレ)に血管内皮細胞を播種した。次いで、第1電極および第2電極を、培養容器内の血管内皮細胞の培養液と接し、かつ、互いに間隔をあけて配置した。その後、第1電極および第2電極を介して培養液に、周波数1MHz、ピーク間電圧88Vppの高周波を1分間適用した。高周波の適用は、繰り返し周期が1秒、デューティー比が40%のパルス印加とした。その後、培養器にて血管内皮細胞を24時間培養した。培養後の血管内皮細胞を回収してRNAを抽出し、qPCRにより遺伝子発現を確認した。
高周波の適用時間を3分間とした以外は実験1-1と同じ条件で遺伝子発現を確認した。
実験2では、対象として手術余剰皮膚を用い、実験1と同様に、周波数1MHz、ピーク間電圧88Vppの高周波を適用して血管構造の変化を確認した。高周波は、3分間適用した。高周波の適用は、繰り返し周期が1秒、デューティー比が40%のパルス印加とした。また、高周波の適用は、1日1回行い、1日目、3日目および5日目の血管構造の変化を確認した。血管構造の変化の確認は、血管構造を可視化することによって行った。
上述したとり、血管内皮細胞を使った実験1と、手術余剰皮膚を使った実験2のそれぞれの結果より、高周波の適用が血管の安定化や血管構造の維持に関わっていることが明らかになった。
