摘要：
The present invention is directed to topical compositions, comprising isoflavone nanoparticle compositions. The isoflavone nanoparticle compositions contain isoflavone in the form of nanoparticles and preferably a carrier. In the topical compositions recrystallization of the isoflavone to bigger particles is avoided.
