The present invention provides: a colloid having a self-iontophoresis capacity, comprising elastomer microparticles and a piezoelectric layer encompassing the same; a preparation method therefor; and a cosmetic composition containing the same. According to the present invention, iontophoresis occurs by itself without the help of additional instruments, thereby allowing water-soluble active ingredients in a cosmetic composition to be effectively and transdermally delivered and absorbed. La présente invention concerne un colloïde présentant une capacité d'auto-iontophorèse, comprenant des microparticules d'élastomère et une couche piézo-électrique l'entourant, un procédé de préparation associé et une composition cosmétique le contenant. Selon la présente invention, l'iontophorèse se produit d'elle-même sans l'aide d'instruments supplémentaires, ce qui permet à des ingrédients actifs solubles dans l'eau compris dans une composition cosmétique d'être absorbés et administrés efficacement et par voie transdermique. 본 발명은 엘라스토머 마이크로 입자 및 이를 둘러싼 압전층을 포함하는 자기이온영동(self-iontophoresis) 성능을 가지는 콜로이드, 이의 제조방법 및 이를 함유한 화장료 조성물을 제공한다. 본 발명에 따르면 별도의 기기의 도움 없이 그 자체로서 이온영동이 발생하여 화장료 조성물 내의 수용성 유효성분을 효과적으로 경피에 전달 및 흡수시킬 수 있다.
