摘要：
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.
