Exosomes are extracellular nanovesicles secreted by several cells in the human and animal body. Consisting of a lipid membrane and encapsulated proteins, they contain biologically active substances such as proteins, DNA, RNA, transcription factors, and metabolites. Discovered in the 1980s, exosomes play an important role in cell-to-cell communication and immune function. They vary in size, content, and function depending on the cell of origin. Exosomes have attracted interest in the field of Dermatology due to their potential applications in the treatment of scars, skin rejuvenation, hair regeneration, and other dermatological conditions. However, further clinical studies are needed to prove their efficacy and safety. Regulatory issues also need to be considered, as the use of exosomes in cosmetics and medical treatments is not yet fully approved in some countries. Moreover, it is important to understand the risks and side effects associated with the use of exosomes before their clinical use. Although promising, more research is needed to explore the full potential of exosomes in Medicine and Dermatology.
