Why can't you keep reusing false eyelashes past 4 or so uses?

You can wear them, they just will soon get worn out and stuff.

Not only do they not last and stay in tact very long - its unhygenic to wear them for more than their suggested use. Everytime you wear them they are being exposed to bacteria, dirt, grime, makeup, etc. Its the same with anything else…such as makeup. Your supposed to replace it over a certain period of time because of bacteria.

if you love wearing false lashes but dont have the money to keep buying pairs, on ebay you can get 60 pairs for $10 US, pretty good :)

Well no you dont have to just throw them away you can reuse them as long as you keep them in good and clean condition. the best thing to do is always alpy it on with a pair of twezers and remove them carefully making sure the shape is still how it was when you first bought it. if you want a wacky sort of look then yeah put muscara on but that means your lashes wont last long. best thing is to do is just have the lashes n no extra muscara make sure you dont put etra eyeliner over it either get black adhesive or the clear one wich once dries out there is no need to cover with eyeliner. when taking off the tray make sure you dont peal it off as it will not have that curvy eye shape so make sue u sort of slide it down with the side of your thumb keeping it the shape it should be and i agree with one of the comments already up there jus buy a pack of 10 at once from ebay, it’s really cheap.
