Sure, you may have already planned your outfit and found the perfect sexy-yet-romantic hairstyle and sultry-yet-sweet makeup look for Valentine's Day, but there's a pretty important element you do not want to forget: soft, kissable lips.

Let's face it: who wants to smooch someone with a dry, flaky mouth? And in winter, that's exactly what most of us have -- but we can fix it. Just follow this step-by-step guide:

First, you need to exfoliate your lips to get rid of the flakes. You could use a lip scrub product to do the job, or for a more MacGyver approach, just gently brush your lips with a wet toothbrush, or check out this video.

After exfoliating, apply a super-rich lip balm to seal in moisture. You can use the classic Vaseline, or any of these awesome balms.

A few nights of that routine and your lips should be in good shape (it also helps to keep a lip balm on hand during the day so you don't lick your lips -- that just dries them out more). Now on to the fun stuff: what kind of lip style you want. (This quiz can help if you're unsure.) Basically you need to decide if you want to use a plumper, lip gloss, lipstick or just go au naturale. Check out the pros and cons below:

Lip plumper

Pros: Full, pillowy lips he just has to kiss.

Lip gloss
