The results revealed that iontophoresis could significantly improve the penetration of SLN. The fluorescence of images indicated that the accumulation and the depth of QDs-SLN reached in skin increased with times. Anodal delivery of QDs-SLN resulted in a higher accumulation of QDs-SLN in skin than those of cathodal delivery. Furthermore, the vertical images of skin showed that fluorescence assemble in follicle and dermis, indicating that follicle and the junctions between the corneocyte clusters provide the pathway for SLN penetration into skin.
