How many MAC Cosmetics [1] products do you have in your possession? If it's hard for you to recall the total number, but easy for you to rattle off a minimum of 10 essential shades, there's a good chance that you are under the MAC spell.

As you know by now, the product hoarding [2] is just the beginning. From experiencing the extreme high that comes with nabbing the last Ruby Woo to the extreme low of missing out on RiRi Woo, we break down 16 signs you've got it bad when it comes to the revolutionary cosmetics brand.

You know your "Ruby Woo" from "Perfect Score."

And own both to ensure you're "red-y" for anything.

If possible, you try to keep a few backups on hand.
