1. Mascara - 2 to 3 months.

Unfortunately mascara is the first to go, and often the most commonly overlooked. Don't wait for that sucker to dry out!

2. Lip Gloss - 12 months.

Lip gloss lasts a noteably shorter amount of time than lipstick, as you constantly dip the used brush back into the product to be sealed up.

3. Concealer - 18 months.

Concealer has a much longer shelf life than expected, but let's be real - that will be used up much faster than needed.

4. Eyeshadow - 2 years.

Luckily you have time to give each shade its chance to shine!

5. Lipstick - 2 years.

Should it last that long, two years actually seems like a very fair lifespan for a product used on your mouth.

6. Eyeliner - 4 to 6 months.

This shouldn't surprise anyone. Any product getting shoved towards your waterline has gone through a lot.

Highlighter - 2 years

Let your shimmer shine long-time!

8. Blush - 2 years.

Don't worry about running out when you get too pale this winter - this guy is here to stay for a while.

9. Bronzer - 2 years.

You've got just as long to rock a contour, and that sounds like good news to me.

10. Brushes (cleaned) - multiple times per week!.

Find the time. Do it. No excuses. Your skin will thank you!
