Stem cell-derived and plant-derived exosomes: Promising therapeutics for skin healing and regeneration

Abstract

Stem cell-derived and plant-derived exosomes are emerging as promising therapeutic agents in cutaneous repair, regeneration, and rejuvenation. They facilitate wound healing and skin revitalization through multifaceted mechanisms, including immunomodulation, promotion of cellular differentiation, and stimulation of angiogenesis. Additionally, their ability to modulate collagen production and remodeling underscores their potential in addressing skin aging and improving cosmetic outcomes. Consequently, exosome-based therapies show promise for a range of conditions, from challenging wounds and skin aging to pigmentary disorders, hair loss, certain immune-mediated dermatoses. To ensure a comprehensive and unbiased synthesis of the current evidence, this systematic review was conducted following a structured methodology, encompassing a search across multiple major databases over a defined 20-year period. This review systematically outlines the roles and applications of commonly employed plant exosomes and stem cell exosomes in recent years' advancements in skin repair and cosmetic dermatology. By synthesizing the current understanding of their mechanisms and clinical potential, this review aims to highlight viable therapeutic strategies that bridge the gap between medical dermatology and aesthetic medicine.
