The upper lip should be slightly larger than the lower lip with a gentle curve that peaks at what's called cupid's bow. The hinge of the upper lip comes in the form of the central
On frontal view, the ideal upper lip: lower lip ratio is 1:1.6. The vertical height of the upper lip should be less than that of the lower lip.
The golden ratio as it applies to the lips means that for optimal beauty, the following lip characteristics should all be as close to this ratio as possible: The bottom lip should be 1.618 times larger than the top lip. The top lip should protrude 1.618 times more forward than the bottom lip (as seen from a side view).
The Golden Ratio. If we follow the Phi Ratio of Beauty, otherwise known as the “Golden Ratio” of 1.618, the perfect lips would be 1.618 times larger than the top lip and 1.618 times wider than the width of the nose. If you're determined to accentuate your lips, you may find it helpful to keep these proportions in mind.
Based on their results, a pair of “average lips” has measurements of 7.8mm for the upper lip at the midline and 12.2mm for the lower lip. This gives an upper to lower lip ratio of 1:1.56.
Lips can become swollen if fluid builds up in the skin tissue or if there is underlying inflammation. This causes them to appear larger than usual. Swollen lips have a range of causes, which vary from normal to potentially dangerous.
As you age, your body's production of collagen starts to slow down, which leads to sagging and reduction of volume in areas of your face, like your cheeks and your lips. Hyaluronic acid production also slows down.
The study polled over 1,000 people in 35 countries. Of those polled, 60% said they found a symmetrical, 1:1 top to bottom ratio the most attractive lip (think Scarlett Johansson). The next highest-rated, according to the poll, was a larger bottom lip compared to the top lip (like those rocked by Kylie Jenner).
Full Lips
Full lips are the most common of shapes and are typically defined by lips that are equally plump on the top and bottom. This shape is easy to accentuate and looks great with bold lipstick looks.
Whereas the rest of the face may not show signs of getting older until patients reach their late 20s to 30s, lips can begin to lose important volume starting in the late teens. As the process continues and the mouth loses collagen, the lips can begin to flatten out and appear much thinner in just a few short years.
Generally, an “underbite” is what tends to occur when the lower lip sticks out further than the top, which can cause the lip to jut out slightly. Other common misalignments a dentist can identify include overbites, crossbites and open bites.
M shaped lips refers to the top lip that resembles the letter “M,” and is the most difficult lip shape to treat. This is because the muscles on the upper lip curls inferiorly and the anatomy can be challenging to release.
According to Dr Marisa Coen in her essay for The Science of Relationships, fuller lips have long been desired by women because, as evolutionary psychology suggests, they signify strong mating potential. “Facial features serve as a cue of attractiveness,” explains Coen.
In the study, which was published in the Journal of Cranio-Maxillofacial Surgery, more than 60% of respondents chose the 1:1 ratio between the upper and lower lip as the most attractive shape.
Researchers showed men photos of women, some wearing lipstick and some without and they found that shades of red lipstick captivated men the longest, 7.3 out of the first 10 seconds. And pink lip color was just behind that with 6.7 seconds out of the first 10. Fuller lips were also found to attract the eye for longer.
Heart-shaped lips are similar to Cupid's Bow lips, as the top lip has a defined dip. The subtle difference is in the bottom lip. Heart-shaped lips have a bottom lip that is fuller towards the middle and thinner at the sides.
The Russian technique is a group of techniques that basically achieve height on a lip. This means the pink of the lip is raised higher on the top lip and gives the illusion shortening the philtrum. Equally the bottom lip drops lower giving a deeper 'v' shaped curve toward the chin.
Another new lip filler trend is Cherry Lips. This technique adds more volume to the middle areas of the lips to create a unique cherry-like shape. The added volume makes the lips resemble a pair of cherries hanging horizontally from the corners of the lips, which is where this lip filler trend gets its name.
A Cupid's bow is where the upper lip comes to two distinct points toward the center of the mouth. This looks a bit like the double-pointed bow that Cupid is often depicted holding. Most people have some sort of Cupid's bow, though some are more pronounced than others.
If your lips are uneven, it may be due to your facial muscles being underdeveloped or weak. This could be the result of a condition such as Lyme disease, or it could be present from birth.
A surgical procedure offers the most significant results. For lips, this procedure is known as a lip lift. A lip lift involves making an incision and reshaping the lips to alter their look. In the case of asymmetrical lips, the surgeon can help you achieve a more even, symmetrical appearance.
Understanding Aging Makes Beauty Timeless
Figure 1: In guys, the maximum upper lip thickness is reached around age 16, whereas it maximizes at 14 in girls; however, it begins to thin in both sexes after age 16.
Based on what these online people said, we now know that the most attractive faces are those with a lower lip that's about twice as big as the upper lip; and an overall lip size of about 9.6 percent of the total area of the lower third of the face.
According to Ryan Neinstein, M.D., a plastic surgeon in New York City, our lips are made up of blood vessels, which become dilated during kissing.
