Exosomes derived from mesenchymal stem cells: A novel agent for skin aging treatment

Skin aging, influenced by both intrinsic and extrinsic factors, leads to structural and functional deterioration characterized by wrinkles, reduced elasticity, and impaired wound healing. Mesenchymal stem cell-derived exosomes (MSC-exos) have emerged as a promising therapeutic option, offering multifaceted benefits for skin rejuvenation. These nano-sized extracellular vesicles exhibit exceptional bioavailability, biocompatibility, and immunomodulatory properties, addressing challenges associated with conventional treatments. MSC-exos enhance collagen synthesis, modulate inflammation, and promote angiogenesis through molecular pathways such as PI3K/Akt and Notch signaling. Furthermore, their ability to deliver bioactive molecules precisely to target cells underscores their therapeutic potential in skin repair and anti-aging applications. However, challenges remain regarding large-scale production, targeting efficiency, and regulatory frameworks, warranting further research to translate these innovative therapies into clinical practice.
