Abstract

This study compared the ability of Nanostructured Lipid Carrier (NLC), Solid Lipid Nanoparticles (SLN), and Cream systems in delivering para Methoxycinnamic Acid (PMCA) to the dermis layer of the skin. Wistar rats were used as research subjects. NLC and SLN were made by applying the high shear homogenization method. Nile red was used as a penetration indicator based on its fluorescence. The interaction between fluorescence labeled NLC, SLN, or Cream and rat skin was visualized by fluorescence microscopy. Observations were made after 2 and 4.5 h of smearing the test sample. From the observations, it was known that the system/lipid base could penetrate the stratum corneum for delivering drugs. Penetration speed differs among systems as does the number of PMCAs that can be delivered. In this study, it can be concluded that the NLC system is able to deliver PMCA more quickly and in greater quantities to the dermis than SLN and Cream.
