Vitamin K is a fat soluble compound which is synthesized by the gut microbiota and produced in many tissues within the body. Considering its role in the liver as a cofactor for gamma carboxylase enzymes, treatment of dark circles and pigments under the eye among others. It is clear that is some circumstances vitamin K has to cross biological barriers, particularly, when the vitamin is produced by microbiota in the intestine or applied topically on skin. Thus it is important to develop methods that allow studies of vitamin K permeability through the skin including its participation in redox reactions and transdermal permeability. Taking into account that transdermal permeability is strongly limited for high molecular weight compounds, i.e., compounds with higher than 500Da, the study was conducted with vitamin K of  lower molecular weight. Specifically vitamin K4 model, i.e., 1,4-dihydroxy-2 naphthoic acid, with molecular weight of 204g/mol. Vitamin K4 is suitable for this kind of study , because it can work as reducing (antioxidant) compound as well as has relatively beneficial physicochemical characteristics for transdermal permeability. Permeability studies were conducted with skin covered oxygen electrode and franz diffusion cell. Data from measurements were analyzed to estimate diffusion coefficients, apparent Michaelis-Menten constants and flux of a vitamin K4 model whilst contribution of different permeability pathways was determined theoretically.
