Lyotropic liquid crystals (LLCs) are organized mesophases with intermediate properties between liquids and solids. The LLC and its liquid crystalline nanoparticles (LCNPs) have attracted great interest from the scientific community in recent years as potential drug delivery systems due to the high internal ordering and symmetry with a wide interfacial area.This article aims to gather information and to provide a description of the highly organized structures of LLCs. Updates on production methods and new insights for LCNPs optimization and physico-chemical and morphological caracterization techniques were discussed. We also discussed why these systems proved to be a platform for the design of nanocarrier drug delivery, with an emphasis on topical and transdermal applications.Drug delivery platforms are of particular importance to improve the biopharmaceutical aspects of therapies topically. Although several systems can be used, LLC or LCNPs appear to be favored due to their similarity to the lipid structure of the skin. The highly ordered structure and the possibility of chemical modifications make it possible to obtain better clinical responses. The results of several studies support the innovations in this field and predict that these systems can innovate the market of technologies for the treatment of cutaneous diseases and cosmetology.
