Psolarea corylifolia extract that contains bakuchiol is known to have anti-microbial, anti-inflammatory and anti-scarring effects. In this study, a vesicles such as liposome, niosome, and transfersome were produced to encapsulate P. corylifolia extract and measured their stability and physiochemical property. The skin permeation and partitioning of P. corylifolia extract in the vesicles were elucidated in nude mouse skin by using Franz diffusion cells after topical application for 24 h. After storage at 25, 40, $70^{circ}C$, and light, the stability of bakuchiol incorporated into the vesicles was maintained for 30 days. The optimal concentration of P. corylifolia extract entrapped into the vesicles was found to be 5~10%. From the physicochemical studies, after storage at 4, 25, and $40^{circ}C$, the viscosity and particle size of the vesicles remained in 30~80 cP and the nanosize range for 6 months, respectively. From the permeation experiments, niosome showed a higher amount of bakuchiol permeated through the mouse skin compared to liposome and transfersome after 24 h. From these results, niosome and transfersome could be a good bioavailability enhancement system (BAES) for P. corylifolia extract to improve the skin permeation and stability.
