The aim of this thesis was to formulate and evaluate topically applied folic acid nanostructured lipid carriers (NLCs) to offer sustained antioxidant and antiaging effects. FA NLCS were prepared by hot high pressure homogenization. Encapsulation efficiency (EE), in vitro release, ex vivo permeation and skin targeting were evaluated. Characterization of selected formulations followed, in addition to stability and water occlusion. Further, histology and antioxidant potential were evaluated. Encapsulation efficiency exceeded 95%. Incorporation of oil into solid lipids causes reduced crystallinity and more imperfections in the crystal lattice providing high drug encapsulation. Formulations with 30% oil showed maximum skin targeting, water occlusion with high efficiency of hydration and antioxidant potential
