2. The 1930s Freckle removing machine from Hell
This machine is the nightmare you have when you really hate yourself. Developed in the 1930s by Italian physician M. Matarasso, this Frankensteinian machine used carbon dioxide in the form of dry ice to freeze freckles. The only thing that would make this machine scarier is if it had electrical bolts zapping everything in tarnation. But despite its fearsome visage, this freckle-freezing gizmo was fairly innocuous. The dry ice was shaped into a pencil and used to briefly touched each freckle. After a week or so, the freckles dropped off.
Over time, this scary-looking machine has morphed into more sophisticated methods to remove freckles, and many of these methods still use carbon dioxide. This includes laser treatments that use carbon dioxide beams to remove age spots, freckles or scars.
Who knew this machine wasn’t so hellish after all?
