Todd tested the lip sensitivity of 23 people using a range of 1.5 centimetre diameter perspex discs with grooves cut into their surface. The distance between the grooves ranged from 0.25 millimetres to 3.5 millimetres. They found that the lower lip was more sensitive than the upper lip at detecting the grooves.
When scientists list the top areas of the body in terms of sensitivity, the lips and fingertips are often ranked as the areas with the highest concentrations of receptor cells [source: Society for Neuroscience]. This sensitivity is also connected to the brain.
As mentioned above, lips are extremely fragile because they do not have any sweat glands or sebaceous glands and only produce a small amount of melanin. The best way to protect them is to regularly use a lip balm with SPF. Summer or winter, you should always have one with you!
The infraorbital branch of the maxillary division of the trigeminal nerve (cranial nerve V2) supplies the upper lip. The mental nerve derived from the mandibular division of the trigeminal nerve (cranial nerve V3) allows for sensation from the lower lip.
Why Do You Get Swollen Lips After You Kiss Someone? When you kiss someone, your lips touch and press against their lips. This can cause your lips to swell up as a reaction to the pressure, and an increase in blood flow within the lips.
Some believe that kissing with tongue is a natural evolutionary progression that aids in mate choice. Others, citing cultures where kissing with tongue is not only absent but looked down upon, believe making out is a specific learned behavior that's gained popularity due to media consumption and globalization.
Lips are composed of a complex of muscles known as orbicularis oris. It's the orbicularis oris contracting that gives us the ability to play the trumpet, whistle or kiss.
They are visible because the lips have one of the thinnest layers of skin on the body. 2. They are the most sensitive part on your body-they have over 1 million nerve endings.
No, you should never pick or peel the dead skin off your lips because you could accidentally peel off too much and cause damage that will take a long time to heal. Careful exfoliation is a much safer way to remove dead skin from the lips.
The Blessed Cupid's Bow
As well as having a voluptuous look, the most attractive lips often also feature a striking cupid's bow, which catches the eye due to its sharp points.
“Generally, your natural lip shade is the same colour as your nipple. If you are using this method to search for a nude lipstick, it will give your the perfect nude lip for your skin tone.” Since the nipple/lip hack has made the TikTok rounds, there's been a reported spike in “nipple shade” lipsticks.
"The sensation on the lips is not universal," says Todd. "The sensation on a person's bottom lip is actually much greater than on the top lip." Sensory receptors in our skin are essential for enabling the brain to control our body's movement.
The lips and tongue contain a huge number of nerve endings, which trigger signals to the receptors in the brain. This is what causes the lip sensitivity you experience when having a smooch.

Severely chapped lips may take longer to heal, but the average time is two to three weeks to recover completely. If you treat chapped lips as soon as you notice a problem, your lips will heal much faster and you can avoid potential complications like infection.
Nerve damage
If the lips are exposed to extreme heat or cold, are sunburnt, or come into contact with a toxic substance such as bleach, it may damage the nerves and lead to tingling, numbness, and pain.
The trend involves lifting the lips with Steri-Strips and then providing a significant plumping effect using dermal filler to over-emphasise the Cupid's bow.
Depends on the guy. Usually, thicker lips are better for kissing, as they are fuller, and it typically feels better to press your lips to lips that are full. Also, often time thicker lips makes for better…. I'm gonna say it……
While some people may have naturally thin lips, they can also be a sign of ageing, sun exposure or a result from smoking. As you get older the collagen in your lips breaks down and the muscles tire, leaving your lips looking and feeling thinner.
Less Than 5% of People Have This Rare Lip Shape #anatomy Cupid's bow lips, named after the bow-like shape that resembles Cupid's bow and arrow, are characterized by a distinct and alluring lip shape. These lips have a well-defined curve on the upper lip, creating a natural indentation in the center.
Kiss someone when you feel ready, regardless of how old you are. Around ages 12-15, people often start having their first kiss. Don't feel pressured by other people your age kissing people, and don't rush into kissing someone if you are apprehensive. You'll know intuitively when the time feels right.
Electric impulses bounce between the brain, lips, tongue and skin, which can lead to the feeling of being on a natural “high” because of a potent cocktail of chemical messengers involved. A passionate kiss acts like a drug, causing us to crave the other person thanks to a neurotransmitter called dopamine.
Adrenaline Is Unleashed
"The heart rate goes up, muscle tension increases, our breathing rate speeds up, and blood flows to our internal organs." It's why you might feel "weak in the knees." But this feeling also plays a role in assessing your chemistry.
