In beauty as in life, sinful deeds get done. But unlike life, when we might act on a wicked impulse with the most atrocious results, beauty sins are much easier to correct. Here are 10 beauty sins, from the innocently bungling to the outright jarring. Think of them as gentle ‑- and not so gentle ‑- reminders of what not to do. Ever.

Reprehensibly Dark Lip Liner

If friends are asking you how you enjoyed your hot cocoa and you didn't have hot cocoa, you're probably wearing lip liner that's too dark. Stop it. You look silly. Go find a lip pencil that matches your lip color.

Scandalously Sleeping with Your Makeup

Don't cheat on your face. Because your skin is rich in its own natural oils, gets coated with a daily blend of environmental debris and suffocates under makeup, you've got to wash your face every night or your pores will suffer.

Shamefully Trying to Hide Your Skin Color

Sorry, but you won't look like you have a honeyed and sultry tan if your foundation's too dark ‑- you'll just look dirty. And you won't appear porcelain skinned if your foundation is too light ‑- you'll just look like a ghoul. So gals, please, choose your foundation in good, clear light and blend it onto your skin carefully.
