It’s Super Sterile
Botox is manufactured in a state-of-the art facility, under the strictest quality and safety standards. Every vial is filled and sealed in a completely sterile environment. The air in the room is filtered and changes in excess of 200 times an hour and only a relatively small number of highly-trained technicians are permitted to enter. And when they do enter, they are covered from head to toe in a specially-designed sterile suit. Even the water used to wash the inside of the vials before they are filled is purified to “Water for Injection” standard.
