I am interested in these dermarollers but at the same time also worried about safety and hygiene.
Many of the cheap ones are made in China. What if they are contaminated with bacteria or viruses?
And since they are made of plastic can you even use medical disinfectants which contain alcohol to clean them?
You needed to be able to use stuff on them which kills bacteria and viruses to be really safe.
What I also read is that needles longer than 0.2 mm are too dangerous. But many of the rollers have much longer needles.
The longer the needles the more damage you cause to the skin. This seems risky to me. But 0.2mm on the other hand might
not be effective enough. It's really tricky.
