Microneedling with exosomes – what is it?

Microneedling with exosomes has received increasing attention in aesthetic skin care. The treatment combines traditional microneedling with a product that contains or is marketed as containing exosomes.

Exosomes are very small particles produced by cells and used as part of communication between different cells. Research into their possible use in skin rejuvenation, scars, pigmentation, and hair loss is promising, but the field is still relatively new and there are important questions regarding product contents, quality, standardization, and long-term safety.

What are exosomes?

Exosomes are a type of very small extracellular vesicles. They are surrounded by a membrane and can transport various biological substances between cells, including proteins, lipids, and nucleic acids such as RNA.

They are naturally formed by many different types of cells and are part of the body's communication system between cells.

Exosomes are therefore not the same thing as stem cells. They are not living cells and cannot divide in the same way as a cell. However, the contents of exosomes can affect how recipient cells behave.

What does microneedling with exosomes involve?

In regular microneedling, thin needles create a large number of controlled microchannels in the skin. This triggers a local repair process and is used, among other things, with a focus on skin texture, scars, and fine lines.

In microneedling with exosomes, the needling treatment is combined with an exosome-based product, often by applying the product in connection with or after the actual microneedling treatment.

One reason the combination has become popular is that microneedling temporarily affects the skin barrier. This has made the method interesting as a way to combine mechanical stimulation with topically applied biologically active products.

However, this does not mean that just any product should be applied to newly treated skin. As we describe in our guide on serum during microneedling, the product's formulation, intended use, and hygienic quality need to be assessed separately.

What could exosomes do in the skin?

Interest in exosomes is based on the fact that they can contain biological signaling molecules that affect communication between cells.

In laboratory and animal studies, exosomes from different cell sources have been linked to processes such as:

• cell communication,
• tissue repair,
• inflammatory processes,
• formation and remodeling of the extracellular matrix,
• and signaling that may affect collagen production.

However, it is important to distinguish between biological mechanisms observed in laboratory settings and documented clinical results in humans.

Just because a mechanism appears promising does not automatically mean that all exosome products have the same effect or that the results from one specific product can be transferred to another.

What does the research say about microneedling and exosomes?

Research is still limited but growing rapidly.

A systematic review published in 2026 examined studies in which microneedling was combined with exosomes in dermatology. Eight studies with a total of 171 participants were included in the final analysis.

The studies included, among other things:

• skin aging and skin rejuvenation,
• hyperpigmentation and melasma,
• enlarged pores,
• acne and atrophic scars,
• and androgenetic hair loss.

Several of the studies reported improvements in, for example, skin texture, wrinkles, elasticity, pigmentation, or hair parameters. But the studies were small – from only a few participants up to around 60 – and the follow-up periods were often short.

The researchers behind the review therefore concluded that the results are promising but that larger studies, better standardization, and longer follow-up are still needed before the treatment's effectiveness and long-term safety can be established.

Is microneedling with exosomes better than regular microneedling?

It is not yet possible to say in general.

Some smaller studies have shown better results when exosome products were combined with microneedling compared with control treatments, but the research base is still too limited and heterogeneous to establish that the combination is generally superior to regular microneedling.

An important limitation is also that different studies use different:

• exosome sources,
• production methods,
• concentrations,
• microneedling devices,
• needle depths,
• treatment intervals,
• and ways of measuring results.

This makes it difficult to compare the results directly and even more difficult to say that all treatments marketed as "exosome microneedling" are equivalent.

Not all exosome products are the same

This is perhaps the most important part to understand.

Exosomes can come from different cell types and biological sources. In addition, the methods for isolating, purifying, concentrating, characterizing, and storing extracellular vesicles can differ greatly between manufacturers.

Scientific reviews have identified a lack of standardization as one of the biggest challenges in the field.

The fact that a product is marketed with the word "exosomes" therefore does not automatically tell you:

• where the vesicles come from,
• how they were isolated,
• what concentration the product contains,
• how the contents were verified,
• how stable the product is,
• or what clinical research exists on that specific product.

This is an important difference compared with simply assessing a regular cosmetic ingredient based on its name.

Are exosomes the same thing as stem cells?

No.

Stem cells are living cells that, among other things, have the ability to divide and develop into other cell types.

Exosomes, on the other hand, are small membrane-enclosed vesicles produced and released by cells. They can carry proteins, lipids, and genetic material but are not themselves cells.

Exosomes can be produced from cell cultures where, for example, mesenchymal stem cells are used as the source, which is likely one reason why the concepts are sometimes confused in marketing. But an exosome and a stem cell are biologically two completely different things.

Microneedling with exosomes compared with PRP

Exosomes and PRP are also two different types of biological treatments.

PRP, platelet-rich plasma, is produced from the patient's own blood. The blood is centrifuged to create a plasma fraction with a higher concentration of platelets.

Exosome products, on the other hand, consist of extracellular vesicles or preparations marketed based on containing such vesicles. They therefore do not have to come from the patient's own blood.

This also means that questions regarding source, production, purification, and quality control become particularly important for exosome products.

If you want to read more about the other method, we have a separate guide about microneedling and PRP.

Are exosomes the same thing as PDRN?

No. Exosomes and PDRN are completely different types of biological material.

PDRN, polydeoxyribonucleotide, consists of fragments of DNA. Exosomes, on the other hand, are membrane-enclosed extracellular vesicles that can carry several different types of biological material.

Both occur in modern aesthetic skin care and regenerative medicine, which means the terms sometimes appear together, but they should not be used as synonyms.

Are there risks with exosomes and microneedling?

Yes. There are both risks associated with the microneedling treatment itself and uncertainties regarding the exosome products used.

Microneedling can, among other things, cause temporary:

• redness,
• swelling,
• tenderness,
• irritation,
• and minor pinpoint bleeding.

There is also a risk of infection, pigment changes, and other complications if the treatment is performed incorrectly or if hygiene routines are inadequate.

When an additional product is applied to skin whose barrier has been penetrated, the question of the product's quality, sterility, contents, and intended use is added.

You can read more about the general risks in our guide on risks with microneedling.

Are exosome products approved?

The rules depend on what type of product it is and in which country it is sold or used.

In the United States, the FDA has explicitly warned against the marketing of unapproved exosome products and stated that there are no FDA-approved exosome products for the treatment of diseases or medical conditions.

This is U.S. legislation and should not automatically be transferred to the rules in Sweden or the EU, but the agency's warnings illustrate why the product's origin, documentation, and regulatory status need to be checked carefully.

More information is available in the FDA's consumer information on exosome products.

Can you do microneedling with exosomes at home?

This is not something you should improvise with at home.

Regular microneedling already requires careful hygiene and the right technique. When a biologically active product is also applied on or in close connection with newly treated skin, the product's documentation, quality, and intended use become even more important.

Therefore, do not use a product solely because it is marketed online as an "exosome serum" or "exosome ampoule." Check what the product actually contains, who manufactured it, how the contents were verified, and what it is intended to be used for.

What should you check before a treatment?

If you are considering a professional treatment with exosomes, it is reasonable to ask the practitioner about:

• the exact product being used,
• where the product comes from,
• what type of exosomes or extracellular vesicles it is claimed to contain,
• how the product was manufactured and quality controlled,
• what documentation exists for the intended use,
• how the product is stored,
• and what clinical research exists on that specific product.

A well-known marketing name is not in itself proof that the product is clinically documented.

Which skin concerns have been studied?

Exosomes together with microneedling have been studied in smaller studies for several different aesthetic and dermatological areas.

This includes, among other things, skin aging, wrinkles, pigmentation, pores, scars, and hair loss.

However, it is still too early to say that the treatment is established for all of these areas of use. For some areas, there are only very small studies or short follow-up periods.

If, for example, you are interested in pigmentation, you can also read our established guide on microneedling for pigmentation spots and melasma.

Summary

Microneedling with exosomes is a new and rapidly growing area within aesthetic dermatology, but the research is still at an early stage.

• Exosomes are small extracellular vesicles that transport biological signaling substances between cells.
• They are not the same thing as stem cells.
• Microneedling with exosomes has been studied for, among other things, skin rejuvenation, pigmentation, scars, and hair loss.
• Early clinical studies show promising results, but they are still few and relatively small.
• There is still insufficient data on long-term safety and efficacy.
• Exosome products can differ greatly in terms of source, manufacturing, and documentation.
• PRP, PDRN, and exosomes are three different types of biological material and should not be confused with each other.

It is therefore most reasonable to view microneedling with exosomes as an interesting area of research rather than as a treatment where all effects have already been established.

Frequently asked questions about microneedling with exosomes

What are exosomes?

Exosomes are very small extracellular vesicles produced by cells and can transport, among other things, proteins, lipids, and nucleic acids between cells. They play a role in communication between different cells.

How are exosomes used together with microneedling?

In some treatments, an exosome-based product is applied in connection with or after microneedling. Microneedling temporarily affects the skin barrier, which is one reason why the combination has been studied. However, the product's intended use, quality, and hygienic properties need to be assessed separately.

Does microneedling with exosomes work better than regular microneedling?

Early and relatively small studies have reported promising results, but the body of research is still too limited to establish that microneedling with exosomes is generally better than regular microneedling.

Are exosomes the same thing as stem cells?

No. Stem cells are living cells that can divide. Exosomes are small membrane-enclosed vesicles released by cells and can transport biological material between cells.

What is the difference between exosomes and PRP?

PRP is produced from the patient's own blood and contains a concentrated amount of platelets. Exosome products contain or are marketed as containing extracellular vesicles from a biological source. They are therefore two different types of treatments.

Is microneedling with exosomes safe?

Small clinical studies have reported relatively limited short-term side effects, but there is still insufficient data on long-term safety. In addition, exosome products vary greatly in terms of source, manufacturing, and documentation, which makes product quality especially important.
