You'd be surprised what the world of science has figured out when it comes to romance. One minute, science is launching Neil Armstrong across the void to walk on the moon. The next, it's telling you exactly how to land your fantasy date. Contrary to popular belief, love and attraction is less like a romance novel, and a whole lot more like a psychology journal. Here's what science says is working behind the scenes when Cupid's arrow strikes.



Your lips
Forget about flaunting your curves for a minute. Results from a study at Manchester University found that lips are a woman's most attractive physical attribute. When you think about how much ladies like Angelina Jolie and Scarlett Johansson are lusted after, it's tough to argue against it. For extra credit, pink and red lipstick were found to hold a man's attention even longer. When in doubt, go red—it's a classic and it works.

Strong eye contact


Forget that saying about the eyes being the window to the soul, because they're also the door to keeping a lover's attention. Turns out your pupils dilate a little more when you're attracted to someone. The kicker? People are apparently super attracted to dilated pupils. Lesson learned: never miss an opportunity to fixate your eyes at your intended bae.


Pearly whites


Research suggests that straight, white teeth are more attractive, and it's safe to assume that most folks don't prefer yellow, rotting teeth. We shouldn't even have to tell you this, but brush, floss, and visit your dentist regularly. You'd be surprised how many people don't maintain dental hygiene. It's one of those subconscious signals of health and fertility that evolution so craftily tucked into our DNA to help us survive. Thanks, evolution — now pay for our Invisalign!


Smiling like an emoji

When we say smiling like an emoji, we're talking about the happy-face kind, not the inappropriate-but-well-timed eggplant. One study suggests that men are significantly more attracted to women who smile. It's not like you'll be reeling them in with a grimace.

A higher-pitched voice

High-pitched voices are apparently sexier. Researchers suggest it's because higher voices suggest a smaller body size, which our society deems more attractive. We all know the truth: helium fetish. While we're on the topic, keep in mind that cigarettes won't help your cause as they have a tendency to deepen your voice (and yellow your teeth. And, you know, cause cancer)
