Excuse us for a moment, but we're about to make a profound beauty declaration: life's too short to live it without a lip color you love. In honor of this deep, philosophical truth, we give you four reasons to buy lipstick today.

1. It's a mood enhancer-both shopping for it, and subsequently, wearing it.

Ah, retail therapy-the best kind there is. We don't have the scientific studies to back up this claim, but we're pretty sure trying on new lipstick releases endorphins. Just try not to smile once you've found your perfect pink. Somehow all memories of that hellish 3-hour meeting simply melts away when you dash out of a store with a crisp, new shopping bag in hand.

2. It costs less than the leather jacket you've been eyeing.

Sometimes having champagne taste on a beer budget poses a bit of challenge. We like to think lipstick is the solution to this problem. That jacket you've been lusting after could do serious damage to your bank account if you ever pull the trigger. But, like we already established, a girl's got to shop. That Maybelline Color Sensational Vivids lipstick can be yours for less than what you spent on the salad you had for lunch (and it will be so much more satisfying).

3. It will be flattering even when your skinny jeans fail you.

It's a sad fact of life, but sometimes those skinny jeans that make your derriere look divine just don't slide on as easily as they should. Fortunately, the same is not true for your favorite red lipstick. A good lip color is one absolute you can always rely on.

4. It's an instant confidence booster.

Okay, maybe we're the only ones who have ever swiped on Giorgio Armani Rouge Ecstasy in 503 Diva to tackle our long list of household chores, but there's still no denying that putting on a pretty shade of lipstick instantly gives you the I can do anything attitude. (And if it doesn't, you're not wearing the right lipstick.)
