Lips are, of course, essential for eating and speaking. And whistling. And kissing. And we’d look pretty silly without them.

But if you think that’s all there is to say—and know—about human lips, you’re in for a big surprise. Just take a look at our list of 15  Interesting facts about lips:

Your lips can help you choose a mate.

It’s hard to kiss without lips, and some scientists believe that kissing plays a key role in mate selection. It seems that locking lips brings potential mates close enough that they exchange biological information—via sniffing another’s pheromones. Women are believed to prefer the scent of men whose immune systems differ from their own—and pheromones may be a key to this determination.

Men tend to suffer from mouth cancer more than women.

Women usually use lip balms to protect their lips. This way, their lips stay hydrated and they protect their lips from the UV rays.

Our lips lose their plumpness over the years.

The collagen production around the body decreases with age. Collagen is a vital protein for the body and it helps the cells to regenerate. Another duty of collagen is it gives lips their shape. As we age, lips begin to lose their plumpness.

Science claims that kissing allows a biological information exchange and lets you take in the pheromones of your partner.

This biological transfer occurs at the back of our brains. Kissing is known to have a significant effect on choosing a partner.

Your lips are unique.

Many animal species have lips, of course. But only human lips have such a distinct border between the pinkish, reddish parts and the surrounding skin, according to LiveScience. Scientists call this the “vermilion border.”

Your lips can say something about your sexuality.

Hard to believe, but recent research links the shape of a woman’s lips with her ability to achieve orgasm. Specifically, a Scottish psychologist named Stuart Brody found that women with a prominent tubercle of the upper lip are better able to achieve vaginal orgasm. Who knew?

Bigger is generally better.

When it comes to attracting the opposite sex, big lips are better, the BBC reported. That is, at least where a woman’s lips are concerned. But women seem to prefer men with medium-sized lips, a University of Louisville psychologist told the BBC in 2003.

Your lips aren’t the world’s biggest.

Unless you’re Kristina Rei, that is. The young Russian woman is said to have the world’s biggest lips, and no wonder. She underwent multiple silicone injections, all part of an effort to make her lips like those of Jessica Rabbit of the hit 1988 movie Who Framed Roger Rabbit? Did she succeed? See for yourself.

Lips haven’t always been used for kissing.

“Kissing was very restricted up until very recently to areas of Asia—Southeast Asia mainly—and Europe until the conquests in the 1500s,” Dr. Vaughn Bryant, professor of anthropology at Texas A&M University, said in a written statement. “No one in the New World kissed, no one in Oceania kissed, the Eskimos didn’t kiss, people in sub-Saharan Africa didn’t kiss.” According to Bryant, kissing started in India and spread slowly after soldiers under the command of Alexander the Great brought the custom home with them.

The ability to whistle is related to the ''orbicularis oris'' muscle around your upper lip.

Lips are formed by the muscles around the area. Whistling or kissing happens by the movement of those muscles.

According to some sociologists, red lips are easily associated with vaginas

An experiment done in France found that men tend to find women with red lips more attractive. The reason behind this is that the red lips recall a vagina in a man's subconscious.

Lips can be paralyzed as well.

Lips can be paralyzed in a phenomenon known as "Bell Palsy." This is caused by damaged nerves around the facial area. The people who suffer from this disease have hard time controlling their facial muscles. However, this is a temporary situation.

It takes many muscles to pucker up.

To pucker up for a kiss - or to play that trumpet - you have to contract your orbicularis oris. Scientists used to think the orbicularis oris was a single sphincter muscle inside the lips. But now we know it’s actually a complex of four muscles.

Red lips can make you rich.

Some have said that lipstick makes women more attractive to men because it makes the lips look more like the vagina’s labia. Hmm. But one thing that seems clear is that wearing red lipstick can pay off for women. In a recent study from France, sociologists showed that waitresses who wear red lipstick earn bigger tips—though only from male customers. Waitresses’ red lipstick had no effect on the generosity of female customers. 

Blood gives your lips their reddish hue.

The skin of the lips is thinner than skin elsewhere on the body, consisting of three to five cellular layers instead of up to 16. Thinner skin means it’s easier to see the blood vessels underneath. Of course, this effect is more pronounced in people with light-colored skin.
