The topical and transdermal routes of drug administration are long known to the field of pharmaceutics. These routes have been explored for the delivery of a wide range of therapeutic agents over centuries. However, the anatomy of the skin and the physicochemical properties of molecules limit their transport via these routes. To overcome these challenges, a nano-phospholipid carrier called liposome was developed in the 1960s. Liposomal delivery of drugs was reported to be limited to the upper layers of skin. This led to the development of self-regulating and self-adaptable vesicles known as transfersomes. This review critically evaluates the barriers in delivery across the skin, recent advancements in liposomes, transfersomes and their impact in the pharmaceutical field.
