Exosomes are nano‐sized extracellular vesicles released by the majority of the cell types. Exosomes play a major role in intercellular communication via transferring cargoes between cells and altering specific functions of the target cells. The interest in the biological activities of exosomes has been increasing and their therapeutic role has already been demonstrated in various diseases. Recently, there is growing evidence that stem cell‐derived exosomes (including mesenchymal stem cell, umbilical cord‐derived mesenchymal cell, adipose‐derived stem cell, and pluripotent stem cell) can also be used in a variety of skin conditions due to their regenerative and anti‐inflammatory capacity. In this paper, we will provide a brief overview of recent studies on practical applications of exosomes in several dermatologic conditions and their potential mechanisms. By elucidating the different mechanisms and therapeutic roles of exosomes in various disease conditions, we hope dermatologists and other clinicians to establish better strategies for disease treatment with further research.
