We investigated the pharmaceutical and physicochemical properties of different multivesicular liposome (MVL) formulations for the delivery of Rose Bengal (RB) into skin layers for topical photodynamic therapy. The drug content, uniformity, spreadability and release kinetics of the optimum hydrogel formulation were studied. Skin penetration of the prepared gels was studied in albino mice using fluorescence microscopy and the photodynamic properties were evaluated.
