Exosomes are small extracellular vesicles that play a significant role in intercellular communication. Exosomes are used in regenerative aesthetics to improve tissue homeostasis and target the root causes of skin aging. These vesicles are secreted by various cell types and contain proteins, lipids, and nucleic acids such as RNA and DNA. Exosomes are involved in many physiological and pathological processes, including immune response, cell-to-cell communication, and cancer progression. These tiny vesicles have garnered considerable attention in the field of biomedicine due to their potential applications in diagnostics and therapeutics. They can serve as carriers for delivering therapeutic molecules, such as drugs or RNA, to target cells. Moreover, their presence in various biofluids, including blood and urine, makes them promising candidates for non-invasive biomarkers for disease diagnosis and monitoring. Researchers are actively exploring the diverse functions and applications of exosomes, and their unique properties continue to make them an exciting area of study with the potential to revolutionize various aspects of medicine and biotechnology.
