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.
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.
1. 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.
What's in a pout? Well, quite a lot, as it turns out that full and sumptuous lips are the most preferable lip shape of them all - but according to a global study, there's one key trait that distinguishes the perfect pouts from their equally plump, yet sub-par, counterparts.
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).
1. Angelina Jolie. She has, without a doubt, the sexiest pout in the history of lips. In fact, there are online tutorials for women on how to get lips like her.
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.
A natural-looking lip enhancement can balance other facial features, bringing your face into better harmony. Changing your lips' size and proportion can make surrounding features like a prominent nose or jawline look smaller, creating a more feminine appearance.
Thin top and bottom lips
Women with thin lips—think Kirsten Dunst—tend to be loners and rather timid, according to Haner. Their introverted personality also means that they are self-reliant; they are OK with being alone and are perfectly content with the idea of being independent.
The possible science behind it
It is thought that females desire fuller lips because it signifies strong mating and maternal potential. Basically, the research indicates that we are more likely to be more affectionate towards an adult with softer, childlike features such as jutting cheeks or plumper lips.
Cupid is the rarest of all lip forms. Cupid has a powerful, youthful appearance, and is very prominent in pre-adolescent females. Due to the natural growth process in a female's lips, the fullness of the lips fill in the middle first, then the sides.
Conclusion: Lips tended to shorten in length and widen with age, resulting in a thinner and longer appearance. With regard to physiological parameters, there were important age-related changes in hydration and lip color.
Cupid or Cupid's Bow is the rarest of all lip shapes.
Cupid's Bow on lips is usually very prominent in pre-adolescent girls. As an individual grows old, the fullness of the lips fills in the middle first.
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.
Shape and size of the lips are different in ethnic groups and have a lot of diversity. Thin lips are seen at European Caucasian, thick or very thick lips are seen in black people and combina- tional lips are usually seen in Orientals. The middle lips are the most common type with average size of 8-10 mm [13].
According to a survey done by the Insider among over ten thousand people from 35 countries; the majority of participants picked the most symmetric and full lips over others. The study also indices that pouting lower lip is almost as attractive as having full lips.
Studies have also shown that Caucasian women were found to have thinner lips than Asians, with the smallest upper lip height and volume.
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.
Thin Lips
If both your upper and lower lips are not so full, you likely fall under this category.
Lip serum, lip plumper gloss, lip plumping powder and lip plumping balm all basically rely on one of three primary methods to deliver temporary lip volume: They irritate your lips, they use a circulatory stimulant, or they trap moisture in your lips to make them swell.
Augmenting your lips with dermal filler would make them appear fuller and likely help change the proportion of your face. Your nose shape wouldn't change but fuller lips could help balance your features.
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.
Most people have some sort of Cupid's bow, though some are more pronounced than others. Because of corrective surgery, people born with a cleft lip may have one side of the bow look more pronounced than the other, and people who have lip fillers may not have as pronounced of a bow.
So, eyes are definitely an asset to consider. Lipstick and lip gloss were made for a reason, you know. Guys do like to look at women's lips, especially if they look thick and youthful. Acne is never sexy, ladies.
