Where it fits in your suite

Practices place the high-load concentrate in the same finishing step as the standard concentrate, applied topically once the device work is complete.

  1. After microneedling

    Applied topically once the microneedling pass is complete.

  2. After fractional laser

    Applied topically as the closing step of a fractional laser session.

  3. After RF microneedling

    Applied topically after radiofrequency microneedling, as the final step of the session.

This describes where practices place it in a session, not what it does. Whether and how it is used is the licensed practitioner's decision.

What sets it apart

  • Qualified partner manufacturer

    Manufactured by a qualified partner manufacturer and shipped in the manufacturer's labeled packaging.

    Shipped frozen on cold chain. Stored at -20°C long term and 4°C once thawed, per the manufacturer's handling instructions.

  • Lot traceability

    Every vial carries its lot number, which ties it to that lot's certificate of analysis.

A scientific review of exosome concentration in published research

Laboratory studies consistently report that the amount of extracellular vesicle (exosome) material applied changes how cells respond [1, 2]. Studies often express that amount as a particle count, such as vesicles per cell [2], the same kind of figure the manufacturer states on each vial's label.

  • Cell studies

    What the research shows

    Human skin fibroblasts exposed to more mesenchymal stem cell exosome material proliferated and migrated more, and secreted more type I and III collagen and elastin, in a dose-dependent way [3, 4]. In a study of vesicles from 12 cell sources, given at 20 to 200,000 vesicles per cell, dose shaped the response more than the source did [2].

    Where research is heading

    Researchers are now mapping how vesicle amount and cell source work together, with distinct cellular response profiles observed across the concentration range [2].

  • Animal studies

    What the research shows

    A systematic review of 39 animal studies found that vesicles from stem cells sped skin closure and re-epithelialization in a dose-dependent manner [5].

    Where research is heading

    A review of 64 preclinical studies describes the field moving toward potency-based dosing, which measures the active cargo a preparation carries [1]. International guidelines set out complementary methods for characterizing vesicles, from particle counts to marker profiles [6].

  • Human studies

    What the research shows

    A 2026 systematic review of 16 studies with 503 participants found that most facial studies reported improvement in at least one skin quality measure, and none reported a serious adverse event [7].

    Where research is heading

    Clinical research in aesthetics is building quickly: 16 studies with 503 participants met the criteria for the 2026 review, with facial skin quality as a leading focus [7].

This review summarizes the published research literature on exosome material. The catalog gives the manufacturer's particle count for each MSC exosome format, the same metric researchers report, so practices can compare formats on the scientific terms the literature uses. How much material is used in a session is the licensed practitioner's decision.

What's in the vial

The high-load concentrate carries MSC-derived exosomes with amino acids in normal saline. Each 1.0 mL vial contains approximately 3 trillion microvesicles and each 5.0 mL vial approximately 15 trillion, as stated by the manufacturer, three times the load of the MSC Exosome Concentrate.

Vesicles are characterized by particle count and size, with a certificate of analysis issued for every lot and available on request.

Manufactured by a qualified partner manufacturer and shipped in the manufacturer's labeled packaging.

A practice comparing the two concentrates can read the particle counts on each lot's certificate of analysis side by side.

Frequently asked questions

How does the high-load concentrate differ from the MSC Exosome Concentrate?
It carries three times the microvesicle load per vial, as stated by the manufacturer, with amino acids in normal saline. Each lot's certificate of analysis reports its particle count, so the two can be compared lot to lot.
What documentation ships with an order?
Every vial carries its lot number, and a Certificate of Analysis is issued for every lot and provided on request. Practices with their own documentation requirements should raise them at account setup so we can confirm what we are able to supply before a first order ships.
How should this material be handled on arrival?
Check the temperature indicator included with the shipment before the vials go into storage, and move them to their storage condition promptly. If the indicator reads outside range, contact us before use rather than storing the shipment. Storage and handling conditions follow the manufacturer's handling instructions, which ship with each order.
Who can open a wholesale account?
NPI-verified licensed practitioners. Verification happens before pricing is released, and professional licensure is confirmed for the destination state before a first order ships.
What is the regulatory status of this material?
No exosome product has been approved by the FDA for administration to humans. Material is supplied for topical aesthetic use in clinics and for medical, molecular biology and biochemistry research applications, and is not a tissue product as defined by FDA guidelines. Whether and how it is used in a given session is the licensed practitioner's decision.
