What Are Exosomes, and Why Are They in Your Skincare?
By now, you've probably seen 'exosomes' wafting across your For You Page, maybe sandwiched between a promo code for snail mucin and someone rendering beef tallow. Scroll through SkinTok long enough, and you'll hit a flood of videos hyping exosome therapy, exosome serums, and exosome treatments promising the skin health of a cherub. Skincare companies have seized the term. Marketed as miraculous regenerative agents, you'll find them on $300 facial menus, in post-micro-needling procedures, and across influencers' skincare routines. TikTok content This content can also be viewed on the site it originates from. What Are Exosomes? An exosome is a teeny sac inside a cell, or what a scientist might call an extracellular vesicle. They act as tiny mailbags, shuttling mRNAs, lipids, and other genetic material through the cell membranes from one cell to another. Exosomes are a part of the body's internal messaging system, regulating everything from cell growth to hormone production and gene expression. They're microscopic, measuring about 40 to 100 nanometers across, so small they make a red blood cell look massive in comparison. Scientists first discovered them under a microscope back in the 1960s, but they didn't gain significant attention until the early 2000s. Why Are Exosomes Controversial? In medicine, exosomes are being studied for cancer therapies, neurodegenerative diseases, and drug delivery systems. Because they reflect the state of the cells from which they originate, cancer cells often release exosomes that contain unique molecular fingerprints. Scientists are already using these biomarkers to assist in the early diagnosis of conditions like prostate cancer. The potential for early, non-invasive detection across a range of diseases is substantial. Because exosomes can cross biological barriers and deliver cargo, researchers are also exploring them as vehicles for targeted drugs. Additionally, they hold potential for wound healing, inflammation reduction, and tissue regeneration. Naturally, the beauty industry caught wind. Now, exosomes are in moisturizers, serums, and hair injectables, promising to repair your skin barrier, boost collagen production, and reverse aging.

R3 Stem Cell Publishes Podcast Called Stem Cell Genius to Educate Consumers on Regenerative Medicine
The world's largest provider of regenerative therapies, R3 Stem Cell, has launched a new podcast called Stem Cell Genius. 'With R3's Podcast Stem Cell Genius, we will provide accurate information to FAQ's in layman's terms so people understand what these wonderful stem cell and exosome therapies can or can't do!'— David Greene, MD, PhD, MBA SCOTTSDALE, AZ, UNITED STATES, May 23, 2025 / / -- The world's largest provider of regenerative therapies, R3 Stem Cell, has launched a new podcast called Stem Cell Genius. The podcast will touch on regenerative medicine subjects that will educate consumers on frequently asked questions and provide accurate information to delineate fact from fiction in the industry. The topics will be generated from the vast majority of frequently asked questions received on a daily basis. For instance, in the first episode R3 Stem Cell CEO David Greene, MD, PhD, MBA, explains the basics of what stem cells and exosomes are. In the second episode, Dr. Greene clarifies the differences between stem cells used in the USA versus internationally. According to Dr. Greene, 'There are so many questions surrounding stem cell therapy from the public, and unfortunately there are many unscrupulous actors spreading misinformation. With R3's President Samantha Brechner as the host, we will provide accurate information to FAQ's in layman's terms so people understand what these wonderful therapies can or can't do!' With over 26,000 stem cell procedures performed in the past decade, R3 Stem Cell has over 70 Centers in 7 countries. The company has published 10 peer reviewed research papers over the past 2 years, on regenerative therapies for conditions such as autism, Cerebral Palsy, premature ovarian failure, diabetes and more. With an incredibly broad experience, R3's CEO Dr. David Greene is able to convey a deep understanding of not just what the biologics are, but how they work for individuals and what to expect. Dr. Greene added, 'I'm not interested in fluff content involving stem cell research that won't help people. The topics are directly tied to existing therapies that are changing lives every day. For example, stem cell therapy for autism works amazingly well and is safe. Parents need the latest information to be able to make educated decisions regarding their child's healthcare.' R3 Stem Cell has stem cell clinics in Turkey, Philippines, Pakistan, India, Mexico, USA and South Africa. Each clinic utilizes R3's biologics and best practice protocols. New episodes will be added weekly, with the Stem Cell Genius podcast being available on all major content platforms.

Exosomes: the best skin and beauty secret to know
Many of us haven't heard of exosomes, although they have been used for a few years by clinics and doctors in skin treatments. But now that skincare brands have started to use them in their products, those of us dedicated to trying to improve our complexions will be finding out all about them. Naturally occurring in our bodies, exosomes are microscopic vesicles — structures containing liquids, almost like tiny water balloons — that transport proteins and lipids between cells. What makes them particularly useful is that they also communicate with cells. Which means, according to Dr Jonathan Dunne, a consultant plastic surgeon and the founder of the aesthetic clinic Montrose London which uses plant-based exosomes, that 'they can stimulate production of substances such as collagen and elastin, which are critical for healthy and youthful skin'. Both of those deplete as we age. But when exosomes locate cells that are flagging, they boost them back into action. Cell-regenerating products are nothing new — retinoids, for example, have long been lauded for their ability to help to boost the production of new skin cells. But exosomes, when applied topically, are even better, says Rebecca Cullen-Smith, the education director at the skincare brand Dermalogica. The company has recently launched its Exo Booster, containing exosomes made using bacteria. These, she says, are biocompatible with our skin, and as efficacious if not more so than bovine — or human — derived exosomes, the latter being popular in Asia but not legal for cosmetic use in the UK. • This article contains affiliate links that can earn us revenue The difference between what retinoids and exosomes do, Cullen-Smith says, is that 'retinoids can signal cells to switch biological processes on and off by bonding to specific receptor proteins that drive actions such as strengthening collagen production' whereas 'exosomes are much more complex structures. They not only signal to cells, but also provide critical biological components that are required for specific functions.' In other words, they can stimulate cells to perform actions such as produce collagen and increase elasticity. (According to a paper last year for the International Journal of Biological Sciences, they can also help to suppress inflammation, promote tissue repair and help tissue regeneration.) What difference will they make when looking in the mirror? Other than seeing the brightening and lifting effects from the facial or microneedling treatment during which exosomes would typically be applied like a serum, not a lot — they won't immediately change the appearance of skin like dermal fillers would. But they should improve things over time, as the skin's natural repairing processes are triggered and sped up, resulting in smoothed lines, improved texture and tone, and a plumper, fresher complexion. This, consultants say, usually happens within a month after the treatment. (One third-party clinical trial which compared microneedling alone and microneedling with exosomes showed that the latter produced an impressive 86 per cent greater reduction in wrinkle appearance after three weeks.) For long-lasting results, a course of three treatments is recommended. Katharine Mackenzie Paterson, a London facialist who has started offering bacterial and plant-based exosome treatments to clients, says they can also calm inflammation and restore damaged skin 'so they're perfect for anyone with sensitive or sensitised skin'. • In-clinic cosmetic treatments and at-home gadgets to get now After trying exosome treatments for a few weeks, with Dermalogica and KMP, both of our testers attested to good skin, day after day. 'Like you've consistently had your eight hours of sleep,' said one, with both commenting on how little foundation they're having to wear after their first session. And isn't that, after all, just what we want? Not an altered face — but a refreshed one. Exosome treatments cost from £330 at Dermalogica, £595 at Katharine Mackenzie Paterson for microneedling exosome treatment, £495 at Montrose London,
