What's in the vial
Luxir+ is a concentrated formulation of the Luxir MSC exosome platform. Each 1.0 mL vial contains approximately 3 trillion microvesicles, three times the baseline density of Luxir, suspended in normal saline with high-potency amino acids.
The amino acid matrix supports vesicle stability during handling and reconstitution. Vesicles are characterized by NanoSight NTA and dSTORM imaging with lot-specific documentation.
Same cGMP manufacturing pipeline and single-donor perinatal MSC source as Luxir; batch traceability from cell bank through fill-finish.
Because the concentration step changes vesicle density rather than the source material, Luxir+ and Luxir are comparable lot to lot on the same measurements. A practice evaluating the two can read NanoSight NTA particle counts, dSTORM imaging, HPLC and RNA quantification from each product's Certificate of Analysis and compare them directly, rather than reasoning across two different characterization methods.

Where practitioners use Luxir+
- Topical cosmetic use where higher microvesicle loading is preferred
- Multi-area topical use after procedures
- Laboratory research requiring higher exosome density per volume

How every lot is tested
Each lot of exosome material is documented by a certificate of analysis that covers three stages, from the tissue donor to the finished vial. The tests are listed here; the acceptance criteria and results are shared with verified practices on request.
Donor screening
The placental tissue donor is screened before any cells are banked.
- Microbial testing with strain typing
- HIV-1 and HIV-2, by antibody and nucleic acid testing
- Hepatitis B, by core antibody, surface antigen and nucleic acid testing
- Hepatitis C, by antibody and nucleic acid testing
- HTLV I and II
- Syphilis
- West Nile virus
- Cytomegalovirus
- Risk assessment for Zika, Ebola, malaria, Chagas disease and CJD
Cell bank safety
The master cell bank is tested for contamination and adventitious agents.
- Sterility by membrane filtration

A certificate of analysis is issued for every lot and provided on request. Requests are reviewed for NPI-verified practices in the practitioner portal.
Regulatory & handling
Cold-chain shipped frozen. Stored at −20°C long term and 4°C once thawed, per the manufacturer's handling instructions. Supplied for topical aesthetic use by licensed practitioners, as labeled by the manufacturer, and for laboratory and IND-authorized clinical research. Not sold for injection, infusion or any other route into the body, and not intended to diagnose, treat, cure or prevent any disease. The higher loading is a property of the supplied material; the amount used in a session is the licensed practitioner’s decision.
Frequently asked questions
- How does Luxir+ differ from Luxir?
- Luxir+ carries three times the baseline microvesicle load of Luxir in the same normal-saline presentation. It is characterized the same way, by NanoSight NTA, dSTORM, HPLC and RNA quantification, so the two can be compared lot to lot on the same measurements.
- 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.
