Formula 1900
A single-use lyophilized powder in a sealed glass vial, reconstituted at the point of treatment and applied topically for the appearance of smoother, more radiant-looking skin.
For professional topical use only · Not for injection
The Product
Every box contains a single vial and a single dose. There is no larger format, no multi-use bottle waiting in a refrigerator between clients, and nothing to portion out by eye.
The powder is freeze-dried and sealed under a crimped cap. Dry, it holds at ambient temperature — no refrigeration, no cold-chain shipping, no inspecting a courier’s ice pack on arrival. Water is what makes an exosome preparation delicate, so the water is taken out at the factory and added back by you, at the last possible moment.
The directions are on a brushed stainless steel card seated in the tray beside the vial. Paper leaflets leave with the packaging. A steel card tends to stay on the counter.
Inside the Vial
Lyophilization removes water from the formulation and leaves a stable cake of powder behind. That is what allows a sealed vial to sit at ambient temperature rather than in a freezer. The freeze-drying and filling are performed in the United States.
The powder is reconstituted with 3 mL of sterile water or saline immediately before application, so the product is prepared fresh for each treatment rather than sitting pre-mixed on a shelf.
Each vial states its content on the label: 190 billion exosomes, alongside a short, fully disclosed ingredient list of sugars and buffer salts. Nothing undisclosed, nothing proprietary-by-omission.
Formula 1900 is a cosmetic product for topical use. It is not intended to diagnose, treat, cure or prevent any disease, and no therapeutic or medical benefit is claimed.
The Science
Exosomes are extracellular vesicles — particles roughly 50 to 150 nanometres across, released by cells, carrying lipids, proteins and nucleic acids. They are one of the ways cells pass material to one another.
Most exosome cosmetics use natural vesicles, collected from mesenchymal stem cells, plants or milk. What you get is whatever the donor material happened to produce that day. Formula 1900 takes the other route: engineered extracellular vesicles, produced by a defined, characterized HEK293 cell line under a quality system built to cGMP expectations.
That is why the ingredient list names them exactly — r-Human Embryonic Kidney 293 Cell Extracellular Vesicles — rather than calling them a complex, a blend or a proprietary matrix. A defined cell line is a specification you can hold a batch against.
The vesicles are produced on a proprietary engineered-vesicle platform by our development partner, using a high-yield producer cell line that is the subject of an international patent application. Purification has been developed and validated across multiple batches at production scale.
This describes how the ingredient is produced and tested. It is not a claim of therapeutic or medical benefit. Formula 1900 is a cosmetic product for professional topical use.

Questions
Skincare professionals. Formula 1900 is labelled for professional topical use, supplied to licensed practitioners and authorized distributors, and it assumes the person opening the box knows what they are doing. Read the steel card in full before the first vial.
No, and this is the one answer we would ask you not to skim. Formula 1900 is a topical cosmetic and is labelled not for injection. It goes on the surface of intact skin. Nothing about the format, the packaging or the price changes that.
190 billion engineered extracellular vesicles produced by a defined HEK293 cell line, in a base of sugars and buffer salts — mannitol, trehalose, sodium chloride, sodium phosphate dibasic, potassium phosphate monobasic and potassium chloride. That is the complete list. There is no proprietary complex hiding at the end of it.
A defined, characterized cell line rather than pooled donor material; batch testing for particle count, identity, purity and sterility; and a single-dose presentation that lets you use the whole vial rather than guessing how long an opened bottle stays good. It is a deliberately expensive way to make a cosmetic ingredient, and the alternative is not knowing what is in the bottle.
No. The sealed vial sits at ambient temperature, which is the entire point of the freeze-dried format. Once reconstituted it is intended for immediate single use.
3 mL of sterile water or saline. Swirl gently — do not shake hard — until the cake has fully dissolved, then apply.
No. Each vial is one dose for one client. Anything left after a treatment should be discarded, not stored for later. A reconstituted vial has no preservative system and is not intended to sit.
Yes. Each batch is characterized for particle count, morphology, surface-marker identity, purity and residual DNA, and is tested for sterility, mycoplasma and endotoxin before release.
Formula 1900 is lyophilized and filled in the United States from domestic and imported ingredients, and distributed by US ExoTech LLC of Lewes, Delaware. Freeze-drying is the step that determines whether the powder is stable and viable, and it is done here.
Unopened, undamaged boxes can be returned within 14 days of delivery. Once a vial is opened we cannot take it back, for reasons we hope are obvious.
Company
US ExoTech was formed to bring one product to the United States. Not a range, not a regimen — a single vial, held to a single standard.
This is a loud category. It is crowded with language that runs well ahead of the evidence behind it. We have taken the opposite position, and we think it is the more confident one. Formula 1900 is a cosmetic product. We describe it as a cosmetic product. Everything else we have to say is on the label.
What is in the box is the argument: 190 billion exosomes, lyophilized to a powder that keeps at room temperature, sealed in a single-use glass vial and reconstituted by a professional at the moment of treatment. No refrigeration, no decanting, no second dose. Each box carries a stainless steel instruction card, because a product used on someone else’s face should arrive with its protocol attached.
The exosome science comes from a specialist engineered-vesicle laboratory that has worked on this platform for years. The standard of presentation is ours.
01
We make a single thing. There is no good version and better version, no tiered formula. Everything we know went into this vial.
02
Supplied to licensed practitioners and authorized distributors. Applied topically, to intact skin, and never injected.
03
Every figure on this page appears on the carton. We would rather be quotable than impressive.
