Is it bad to use tester makeup?

like in beauty stores or counters where they have tester lipstick, lipgloss, mascara, etc.Is it bad to use tester makeup?
only if it hasn't been used. I don't try on anything - hats, gloves, makeup. People are disgusting.Is it bad to use tester makeup?
It is only bad to use tester makeup when you use the applicator that comes with the bottle. For example, using the supplied lipgloss stick that comes with the lipgloss that is open for testing. Try using the provided q-tips and cotton balls to apply the makeup. If they are none available, it's not worth it!
personally i wouldn't use them at all. someone may have double dipped but there is always germs from ppl touching. it like grocery store samples if they get coughed on or something to that nature or even touched at the sides when others got their samples. GROSS.
heres the scoop oils and corn starch and so on provide the food for bacteria your own make-up is bad after a short period of time check the packages for warnings and dont share make-up with anyone
They always have clean, one use makeup applicators, use those!
tester lipstick/gloss are made to be used individually..how stupid are you..
Can you say where it has been, who used it and what was on their fingers/face when they dabbled in it? I wouldn't use it!!
