Decoding Cellular Language: What Are Exosomes? Posted on February 14, 2025 by DERMA DECIPHER Exosomesbioactive vesicles secreted by stem cells,ranging from 50 to 150 nanometers in size,Exosomes are tiny,enclosed in a double-lipid membrane. Initially thought to be cellular waste,exosomes were later found to play a vital role in cell-to-cell communication.This groundbreaking discovery earned three scientiststhe 2013 Nobel Prize in Physiology or Medicine.Subsequent research revealed that exosomes aid in tissue regeneration,immune regulation, and anti-inflammatory responses, leading to growing interest in both medicine and aesthetics. In March of this year, Taiwan’s Ministry of Health and Welfare approved the conditional use of human cell–derived exosomes in cosmetics,making Taiwan the fifth nation worldwide to permit human-derived exosome applicationsin the beauty and medical aesthetics sectors. - Exosomesbioactive vesicles secreted by stem cells,ranging from 50 to 150 nanometers in size,Exosomes are tiny,enclosed in a double-lipid membrane.
