Journal / Safety
The limits, stated before the sale.
Who should not do this, what a normal response looks like, what to stop for, and why a cartridge is sterile exactly once. These entries exist to talk some readers out of a purchase, which is the only thing that makes the rest of it worth reading.
Giving this its own subject rather than a paragraph at the foot of a product page is deliberate. A list of exclusions printed under a buy button is not a warning, it is a formality, and it is read by nobody who needed it.
Two things here get argued with more than the rest. That a cartridge is a single use part and no amount of alcohol changes that, and that some people should not use a device like this at all, whatever their skin looks like. Both are inconvenient. Neither is negotiable, and both are cheaper to learn on this page than on your face.
