Exosome Facial and Exosome Skincare: What They Are, What the Studies Show and Approval Status

What are exosomes in skin care and where do they come from

An exosome is a nano-sized particle that cells release to send signals to each other; in skin care it is usually taken from stem cells such as fat-derived cells. [2][4][6] The size usually reported is about 30 to 150 nanometres. [6]

The authors of a 2026 review point out that in aesthetics the word exosome is often used for mixed kinds of particle whose origin has not been proven, and the international MISEV2023 guideline advises calling them EVs or sEVs until it is. [6]

The reviews say there is no single standard way to extract and measure the particles, so products may differ in both source and method. [2][6] The word exosome on a label therefore does not tell you what is inside.

Other trend ingredients people ask about, such as PN, PDLLA and concentrated HA, are compared in [[collagen-stimulator-types-explained]]; read about PN in [[rejuran-pn-polynucleotide-explained]].

Do exosomes help skin and what did the studies measure

Human studies measured hydration, elasticity, wrinkles and pores and reported short-term improvement, but most were not randomized and followed people for only 2 to 12 weeks. [1][3] The table below summarizes the studies we could open, with the limits of each.

A 2026 systematic review of 19 human studies found that most were not randomized, had between 3 and 95 participants, followed them for 2 to 12 weeks, and mostly had a moderate to high risk of bias. [1]

Another review covered 21 studies and concluded that skin became more elastic and hydrated and wrinkles shallower, but its authors list as limits that some studies were small and relied on cell or animal experiments, and that larger trials with longer follow-up are needed before this can be confirmed. [2]

The good safety reports mostly concern products applied to the skin surface, while off-label injection has individual reports of risk. [1] Because follow-up was short, there is no standard figure for how long any effect lasts. [1]

A result measured by an instrument or photograph does not mean everyone sees the same. If you wonder which skin booster suits which skin, read [[skin-booster-which-for-which-skin]].

What are the risks of injecting exosomes into the skin

Injecting exosomes into the skin is off-label, and case reports describe tissue death from lack of blood supply, long-lasting inflamed lumps and scars. [1][4][5] The 2026 systematic review advises avoiding off-label injection and calls for tighter regulation of injectable products. [1]

A 2025 case report describes a 38-year-old man who had ulcerated lesions and dusky skin on both cheeks three days after exosomes were injected into the skin for acne scars. The doctor diagnosed tissue death from lack of blood supply; the scabs fell off by themselves within two weeks, but depressed scars and dark marks remained and lasers helped only a little. [4] This is a single case, so it cannot show how often it happens. [4]

A 2025 case series from South Korea describes four women aged 31 to 42 who were injected outside medical supervision, for example in a beauty salon or a clinic that was not a dermatology clinic. All four had lasting redness, lumps, granulomatous inflammation and scars; they were treated with steroids, lasers or surgical removal, and none recovered completely. [5]

The author of the four cases suggests possible causes, such as a delayed allergic reaction to animal or plant components and contaminants such as endotoxin, but this was not confirmed with a tissue sample. [5]

If an open sore, unusual dark skin or a hard red lump that does not settle appears after a procedure, go back to the doctor who did it or to a dermatologist at once, and you can report it to the Thai FDA hotline 1556. [8]

Is exosome approved: the status that can be checked

The Thai FDA said it has never approved a medical device that uses exosome technology or stem cell components, and the US FDA says there are no approved exosome products. [7][8] This section was checked on 12 October 2026.

Thailand: on 14 July 2023 the Deputy Secretary-General of the Thai FDA said that, after checking products registered as medical devices, it has never approved a medical device that uses exosome technology or stem cell components, and has never approved advertising of this technology, including advertising for use as a facial injection. [8] The statement concerns medical devices for facial injection, not products applied to the skin, and it is dated, so check the current status with the Thai FDA.

United States: on 6 December 2019 the FDA announced that patients in Nebraska had serious adverse events after treatment with unapproved products marketed as containing exosomes, and said that at that time there were no FDA-approved exosome products. [7] A 2026 review reports that the FDA has sent warning letters saying exosome products promoted with regenerative or tissue-repair claims may be unapproved drugs and unlicensed biologics. [6]

South Korea: the author of the 2025 case series says exosome products are mostly approved and sold as cosmetics for application to the skin, without approval for injection in most countries, including South Korea. [5]

So the word exosome on a label or in an advertisement is not proof that it is approved for injection. The Thai FDA advises checking the registration number and the advertising permit number, reading the label and directions, and photographing the product, label and leaflet as evidence. [8]

What to ask a doctor before choosing exosome

Ask whether the product is meant to be applied or injected, whether it has a registration number and an advertising permit number, who is to inject it, and what the plan is if something goes wrong; injections must be done by a licensed doctor. [7][8] The US FDA advises asking whether the FDA has reviewed the treatment and, if it is a clinical trial, asking for the IND number and reading the consent form before signing. [7] It also warns that it has no oversight of treatments done in other countries. [7]

The list below is a starting set of questions; the right answers for you depend on your skin, your health history and the product the clinic really uses.

• Is the product a cosmetic to apply or a medical device to inject? Ask to see the box, label, registration number and advertising permit number. [8]
• If it is to be injected, is there a Thai FDA document that allows injection, and who is to inject it? [5][8]
• Where do the exosomes come from (human cells, plants or something else), and has the product been tested for contaminants? [5][6]
• How do your allergies, raised scars and skin conditions affect the decision?
• If an open sore, dark skin or a hard red lump appears afterwards, what is the follow-up and treatment plan? [4][5]
