looking in mirrorAdmit it. When it comes to your beauty routine, you're not perfect. For years, we've been hearing what we should and shouldn't do to our skin, our hair, and our nails in the name of primping, but for some reason, sometimes it feels good to be bad.

In the long run, our beauty sins will probably come back to bite us in the ass, but what can we say -- some of us are solution people, as opposed to a preventative ones.

Here are 7 deadly beauty sins. You know you've committed at least one.

1. Sleeping with makeup on. You've had a few drinks and you really don't feel like going through your entire night-time routine. No biggie. We've all been there. But sleeping in makeup frequently can cause fine lines, thanks to the free radicals you're exposing your skin to. And also, it can clog pores and cause acne. No thanks.

2. Heat styling. Some of us aren't born with wash-and-go hair, and it's a bummer, because we really have no choice but to break out the hairdryer or flat iron from time to time (or, um, every day). Again, once in a while isn't the end of the world, but when it becomes a daily thing, you're going to see the effects on your hair. (AKA, it's going to look fried.)

3. Tanning. Nothing makes skin glow and seemingly clear up acne like the sunshine. But too much sun exposure will result in wrinkles -- and while a few wrinkles can be distinguished looking in a DVF-kind of way, nobody wants to look like a leather bag.

4. Not drinking 8 glasses of water a day. Seriously, does anybody do this?

5. Exposing your skin to super hot water. Nothing feels quite like a scorching hot shower in the freezing months of winter, but when you cleanse your face with water that's too hot, you're not only drying it out, you might burst a capillary or two. Not cute.

6. Sleeping with hair pulled back. No one likes to wake up with a mouthful of hair, but movements you make in the middle of the night may cause hair to break if it's secured into a ponytail or bun.

7. Over-exfoliating. Exfoliating your face can make your complexion seem brighter and perhaps a bit dewy, but there is such a thing as too much of a good thing. When you exfoliate skin too much (IE, every day), you run the risk of both drying it out and making it super-sensitive.
