Understanding exosomes in facial esthetics and skin aging

Area of Science:

• Regenerative Medicine
• Dermatology
• Cell Biology

Background:

• Skin aging is a complex process involving intrinsic and extrinsic factors.
• Exosomes, small extracellular vesicles, are key regulators of intercellular communication.
• Exosomes possess significant regenerative potential for skin applications.

Purpose of the Study:

• To synthesize evidence on exosome use in facial aesthetics and skin rejuvenation.
• To evaluate in vitro, in vivo, and clinical data regarding exosome efficacy.
• To identify the regenerative mechanisms and clinical outcomes associated with exosome therapy.

Main Methods:

• Comprehensive literature search across PubMed, Scopus, Web of Science, and Google Scholar.
• Inclusion of all in vitro, in vivo, and human clinical studies on exosomes for aesthetic and rejuvenation purposes.
• Search conducted up to January 2, 2026, using specific keywords.

Main Results:

• In vitro studies show exosomes enhance cell viability, ECM production, and reduce inflammation.
• Animal studies demonstrate improved fat graft retention, angiogenesis, and skin remodeling.
• Clinical studies report reduced wrinkles, pore size, erythema, and improved skin elasticity and hydration.

Conclusions:

• Exosomes exhibit substantial regenerative potential for facial aesthetics and anti-aging.
• Methodological heterogeneity and limited high-quality RCTs necessitate further investigation.
• Optimized protocols and long-term safety/efficacy data are required for clinical translation.
