PROBLEM TO BE SOLVED: To provide a beauty apparatus for efficiently introducing active ingredients into the skin while suppressing stimuli felt as pain with applied voltage waveforms as appropriate in conducting the skin and for achieving excellent beauty effect.SOLUTION: In applying voltage to the skin regarding electroporation, value of a digital signal is adjusted so that its increased amount or decreased amount may become substantially stable, an increase/decrease is output, and a change of voltage of an analog signal waveform which D/A converts the same is output by electrode parts 12, 13, so that a nearly triangular repetitive waveform electroporation occurs to the skin due to voltage application, and stimuli felt as pain when conducted is suppressed, perforation on the skin by electroporation is appropriately performed to introduce active ingredients to be introduced into the skin reliably through the skin, and considerable beauty enhancement is achieved.COPYRIGHT: (C)2013,JPO&INPIT【課題】 皮膚への通電の際に、印加電圧波形を適切なものとして、痛みとして感じる刺激を抑えつつ、有効成分の経皮導入を効率よく実行でき、優れた美容効果を得られる美容装置を提供する。【解決手段】 エレクトロポレーションに係る皮膚への電圧印加にあたり、デジタル信号の値をその増加量又は減少量が略一定となるよう調整しつつ増減出力し、これをD/A変換したアナログ信号波形の電圧変化を電極部12、13から出力することで、皮膚には略三角形の繰返し波形の電圧印加によるエレクトロポレーションが生じることとなり、通電時の痛みとして感じる刺激を抑えると共に、エレクトロポレーションによる皮膚への穿孔を適切に進めて、皮膚への導入対象の有効成分を皮膚を通じて確実に導入でき、大きな美容効果を与えられる。【選択図】 図1
