About these notes
Nota Cutis explains product specifications and published research. Study summaries do not provide personal medical advice.
How we compare
We use manufacturer pages, device documentation and official regulatory records where available. Conflicting figures and unconfirmed model matches are identified in the device notes. Recommendations describe practical priorities, rather than clinical superiority.
Research links
A shared wavelength is a reason to read a study, not proof that a particular product was tested in it.
Method
We do not measure devices ourselves. Reported output figures can use different test conditions and cannot be treated as a controlled lab comparison. How to read specifications.
Corrections
We correct records when new source information changes a figure. Prices keep their check dates and markets. Follow the current device manual.
