摘要

Exosomes are small extracellular vesicles produced by most cell types and contain proteins, lipids, and nucleic acids (non-coding RNAs, mRNA, and DNA) that can be released by donor cells to influence the function of recipient cells. Skin photoaging is the premature aging of skin structures caused by prolonged exposure to ultraviolet (UV), as demonstrated by depigmentation, roughness, rhytides, elastosis, and precancerous alterations. Exosomes are associated with aging processes such as oxidative damage, inflammation, and senescence. Exosomes’ anti-aging properties have been linked to various in vitro and preclinical investigations. There are still several unanswered questions about the use of MSC exosomes for skin rejuvenation, despite encouraging results. Uncertainty surrounds the precise processes by which exosomes stimulate the creation of collagen, skin tissue via a variety of mechanisms, including reduced matrix metalloproteinase (MMP) expression, increased collagen and elastin production, and modulation of intracellular signaling pathways and intercellular communication. These findings suggest the therapeutic potential of exosomes in skin aging. This review provides information on the molecular mechanisms and consequences of exosome anti-aging.
