Abstract In attempt to increase cutaneous drug delivery, microemulsion vehicles have been more and more frequently employed over recent years. Microemulsion formulations have been shown to be superior for both transdermal and dermal delivery of particularly lipophilic compounds, but also hydrophilic compounds appear to benefit from application in microemulsions compared to conventional vehicles, like hydrogels, emulsions and liposomes. The favourable drug delivery properties of microemulsions appear to mainly be attributed to the excellent solubility properties. However, the vehicles may also act as penetration enhancers depending on the oil/surfactant constituents, which involves a risk of inducing local irritancy. The correlation between microemulsion structure/composition and drug delivery potential is not yet fully elucidated. However, a few studies have indicated that the internal structure of microemulsions should allow free diffusion of the drug to optimise cutaneous delivery from these vehicles.
