Summary: In this episode of Skin Skin Longevity, Dr. Macrene Alexiades delves into the world of exosomes, a hot topic in dermatology and aesthetics. She begins by explaining what exosomes are—tiny extracellular vesicles that serve as biological messengers, carrying proteins, lipids, and genetic material between cells. Dr. Alexiades emphasizes the importance of understanding the scientific basis behind exosomes, separating fact from marketing hype, and discusses their potential applications in skin health, including anti-aging and wound healing. However, she cautions that while the early data is promising, the clinical evidence remains limited and lacks rigorous human trials.
