When to throw ur old make-up

have you seen any lady throwing away her favorite lipstic/make-up??
As a tendency or love for our favourite lipstic/eye shadow..we continue to use untill it gets completely finished..without giving importance to its expiry..

Be careful! Most beauty products don't have an expiration date, but they do go bad. Periodically purge your medicine cabinet, your bag or wherever else you have makeup tucked away. Here's when to can it:

Mascara
Can it after 3-6 months
It's especially important to change mascara often (even if you have some left). Air can push bacteria into the tube and cause an eye infection.
Eyeliner
Can it after 6 months
Even if you sharpen your eyeliner every week to keep it fresh, bacteria can still grow around the tip. You'll know it's there when the pencil starts to crumble as you're sharpening it.
Foundation
Can it after 6 months
Water-based formulas last a few weeks longer than oil-based ones.
Eye Shadow
Can it after 9-12 months
Old shadows get chalky and difficult to apply.
Blush
Can it after 1-2 years
If your blush breaks, throw it out right away -- and don't salvage the chunks -- they'll be difficult to blend and will look caked on.

Lip Color
Can it after 2 years
