Storage is the least glamorous topic in a med spa and one of the few where a quiet failure can cost you money, compromise patient safety, and create a compliance problem all at the same time — without ever announcing itself. Improperly stored product doesn't look wrong. It sits in the fridge appearing perfectly normal, gets drawn up, gets injected, and the only way you find out something went wrong is through results or a safety issue, long after a thermometer and a log could have caught it. The handling rules are tedious and absolutely worth getting right, because the alternative is a problem you discover too late to prevent.
This is general education for owners, not medical advice. Follow each manufacturer's storage and handling instructions and your own protocols.
