Eye liner - ? months





I know mostly everything except eyeliner. So how much is it?How long can you keep eyeliner for?
i read 6 months somewhere. because it's near your eyes, it gets lots of bacteria on it, which is why you have to throw it away.How long can you keep eyeliner for?
liguid same as mascara pencil till its gone
i not sure, im guessing tho if you use it every day, when you run out that is about how long you should keep it. i am thinking 8 - 10 months....maybe not quite?
my eyeliner is probably a few years old....but that doesn't mean it SHOULD be. lol
You should keep it until it runs out. Thats what i do. I mean it can't clump up, it cant dry out, and it doesn't change colors. It depends what brand you get, i usually get Maybelline, it works ok, but its cheaper than the others. So...it can usually be $3.00 or $7.00
7-8 months.....im sure of that and lipgloss 4 months :D
i don't keep mine for more than 4 months.


but i'm sure you can keep it for up to 8.
