Exosome Therapy With Microneedling: How the Device and the Product Fit

Microneedling is a device step: a pen with fine needles that punctures the skin surface. The exosome product is applied afterward. Studies have tested the pairing, with preliminary results.

For the FDA the two are separate. Some devices are cleared for specific uses. No exosome product is approved.

The device step

Under federal rules a microneedling device for aesthetic use is a device that uses needles to puncture the skin mechanically for aesthetic purposes. It is class II, with special controls. (21 CFR 878.4430)

The FDA's 510(k) letter K241400 describes one cleared system: a pen handpiece, a sterile single-use needle cartridge and accessories, for prescription use by trained health care professionals in a clinical setting. (FDA 510(k) letter K241400)

The product step

The product is a separate item. The same regulation says its classification does not include devices intended for delivering topical products such as cosmetics, drugs or biologics through the skin. We read this as meaning that the device clearance does not cover the product. No exosome product is FDA approved. (FDA notice, December 6, 2019)

A review of microneedling safety advised caution when the device is combined with products not intended to be applied with microneedles. (PMID 34448760)

What studies of the pairing show

A 2026 systematic review of microneedling with exosomes found 8 studies, with 3 to 60 participants each, and asked for more evidence on safety and effect, with longer follow-up. Some of the included studies were on other conditions. (PMID 42027180)

In a randomized split-face trial of 60 adults, a topical extracellular vesicle product after radiofrequency microneedling was linked with a larger improvement in a wrinkle score at week 12 than the device alone. The trial was unblinded and short. (PMID 42635327)

What to ask the clinic

Which device do you use, and what is it cleared for?
Which exosome product goes on the skin, and who makes it?
Who performs the treatment, and what is their license?
How is the needle cartridge handled between patients?
What are the aftercare steps, in writing?

Do not combine a consumer product with needling at home. See the label guide for why we say so.

Quick answers

Is microneedling FDA approved?

The FDA has cleared specific microneedling devices for specific uses, which is a different step from approval. Ask which device a clinic uses and what it is cleared for.

Does FDA clearance of the device cover the exosomes?

No. The regulation that classifies these devices does not include devices intended for delivering cosmetics, drugs or biologics through the skin.
