The Science
Why most CBD cream doesn’t work
The CBD never gets through your skin. Droplet size is the reason, and the milligrams on the label have nothing to do with it.
What is nano CBD?
Nano CBD is CBD carried in droplets small enough to pass through skin. The droplets measure in nanometres rather than micrometres.
CBD is an oil. Your body is mostly water. Oil and water separate, and that separation is where the absorption problem starts.
In a standard topical, the CBD sits inside large oil droplets. Nano-emulsification forces the mixture through high-pressure homogenisation, which shears those droplets down and holds them dispersed in a water-compatible suspension.
Standard CBD
2,000–5,000 nm
Too large for the skin barrier
InstaRx nano
20–50 nm
Passes between the cells
Smaller droplets change two things. They fit through gaps that stopped the larger ones. And they expose far more surface area, so more of the CBD contacts tissue instead of sitting buried inside an oil droplet.
The CBD molecule does not shrink. Molecule size is fixed by chemistry, and any brand claiming otherwise is describing something that cannot happen. What shrinks is the droplet carrying the molecule.
Why doesn’t my CBD cream work?
Because the CBD stayed on the surface. Your stratum corneum is a dense lipid barrier built to keep foreign substances out, and standard CBD droplets are too large to cross it.
Most people describe the same thing: a cooling or tingling sensation, then nothing. That sensation comes from menthol or camphor acting on surface nerve receptors. It arrives within seconds and feels like the product working. It is not the CBD.
When the delivery system cannot cross the barrier, the number on the label stops mattering. A 5,000 mg cream that will not absorb delivers less than a 500 mg cream that will.
| Standard CBD | Nano-emulsified | |
|---|---|---|
| Droplet scale | Thousands of nanometres | Tens of nanometres |
| On the skin | Stays on the surface | Passes into the skin layers |
| In water | Separates | Stays dispersed |
| Surface area | Low | High |
| What the label tells you | How much is in the jar | How much is in the jar |
How to check any CBD brand in four steps
These work on every brand, including this one. Run them before you buy anything.
-
Find the Certificate of Analysis
A COA is third-party lab testing of one production batch. It should be published on the product page, and it should name the lab and the person who signed off.
Walk away if: there is no COA, the lab is unnamed, or there is no batch number.
-
Compare measured CBD to the label
The COA lists what the lab actually measured. Check it against the number on the front of the jar. Independent testing of the CBD market has repeatedly found products holding less CBD than they advertise.
Walk away if: the measured figure comes in under the label claim, or total CBD is missing from the certificate.
-
Read the THC line
Hemp products have to stay under 0.3% THC. There is still a difference between under the limit and not detected at all. Look for a figure in milligrams, not only a percentage.
Walk away if: THC appears only as a percentage with no absolute number.
-
Check the batch date
A certificate covers one batch, not the product line forever. Cannabinoids degrade. A certificate from three years ago says little about the jar shipping today.
Walk away if: the COA has no date, or the same date survives every restock.
Our results against those four steps
Both topicals went to Infinite Chemical Analysis Labs in Jackson, Michigan. Samples were collected 29 December 2025 and the certificates were issued 5 January 2026. Every figure below appears on the published documents.

Both products measured above their label claim. THC came back at 0.000 mg per package, meaning the instrument found none at its detection threshold rather than finding some amount under the legal limit.
The full certificates are linked on each product page. Check the arithmetic yourself.
Questions
Is nano CBD better, or is it a marketing word?
The process is used across pharmaceuticals and food science to improve absorption of compounds that do not dissolve in water. The mechanism holds up. The claim is where brands go wrong, because plenty of products carry the word nano without publishing anything that backs it. Ask for documentation, from us or anyone else.
Will it show up on a drug test?
Nano processing changes droplet size, not which cannabinoids are present. What matters is the THC content of the product itself. Both InstaRx topicals returned total THC of 0.000 mg per package on third-party testing. No company can promise you the result of someone else’s drug test, so if your job depends on it, read the certificate and talk to your employer first.
How fast does it work?
Most people report feeling the topicals within minutes of application. Onset depends on the delivery system far more than the milligram count, and it varies with the person, the spot you apply it to, and what is causing the pain.
Why does a 5,000 mg cream cost less than yours?
Milligrams are cheap. Raw CBD isolate costs very little, so printing a big number on a label costs a manufacturer almost nothing. Nano-emulsification needs specific processing equipment, and testing every batch is a recurring bill. The price reflects the delivery system and the testing, not the headline number.
Is CBD cream legal?
Hemp-derived CBD under 0.3% THC by dry weight is federally legal in the United States under the 2018 Farm Bill. State rules still vary, so check where you live.
Broad spectrum or isolate?
Isolate is CBD on its own. Broad spectrum keeps other hemp compounds and removes THC. Full spectrum keeps everything, including trace THC. Our topicals tested with CBD as the dominant cannabinoid plus a small amount of CBDV, with every THC variant non-detect.
