November 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, exosome-like nanoparticles derived from rose stem cell culture were found to enhance skin quality by increasing collagen production, reducing melanin and inflammation, and promoting cell migration in vitro, suggesting potential aesthetic applications.
April 2023 in “Journal of Investigative Dermatology” This study examined Ashwagandha-derived exosome-like nanoparticles and found that they increased hair growth markers and hair shaft production in human hair follicles ex vivo, suggesting potential for plant-derived exosome therapies in hair loss treatments.
Ashwagandha-derived nanoparticles can promote human hair growth.
July 2024 in “Journal of Investigative Dermatology” Ashwagandha nanoparticles help hair grow by increasing a growth factor.
August 2026 in “ACS Applied Bio Materials” This study found that exosome-like nanoparticles derived from leeks promoted hair follicle stem cell proliferation and migration, enhanced antioxidant capacities, reduced inflammation, and inhibited hair maturation in rats by altering differentiation pathways, suggesting potential therapeutic benefits for managing hirsutism.
