Liposomes prepared by the thin film hydration method could be a better carrier for OMC, an anti-ultraviolet B filter, compared with conventional free OMC formulations, because it has a higher SPF, no irritation potential, an ability to resist lipase enzymatic degradation, and a capacity to modify OMC release and form a reservoir, thus remaining in greater amounts in the stratum corneum and minimizing systemic absorption of OMC. The liposome/OMC formulation is therefore a better vehicle for OMC than conventional formulations.
