I'm not sure if People overseas can see this.
Apparently, if you put your cosmetics in the freezer for 24 hours, it kills off all the bacteria that lives in your makeup.
Some stuff they mentioned, which I knew about, but half of the time, I was sitting there thinking your just saying that to make People who are hell bent against germs rush out and buy replacements.
To their credit, they did mention not to use testers in the shop, that goes without saying, what condition some people leave them in is disgusting!
Surely, if you sanitize things regularly and don't let other People use your liquid things you should be ok right?
