As it turns out, lips with a 53.5 percent increase in surface area from the original image with a 1 to 2 ratio of upper to lower lip that make up about 10 percent of the lower third of the face were deemed to be the most attractive, according to the results.
In the subjective assessments, a lip proportion of 1 to 1.6 (upper lip to lower lip) was rated as most attractive: average score of 4.21 out of a possible 5. The 1:1.6 proportion is widely accepted as the "golden ratio" for beautiful lips.
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.
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.
What are the most attractive lip shapes? 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.
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.
Some studies actually saw that big lips contribute to a great extent to our attractiveness level. Why? It's all about the symmetry of course. As you might be aware, the more symmetrical your face is, the more attractive you will appear to other people.
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.
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.
Full lips are the most common of shapes and are typically defined by lips that are equally plump on the top and bottom.
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.
Earlier explorers from the University of Rochester in New York have already scientifically confirmed that women in red attracts men's attention most of all.
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. This changes the shape of the lips, and the cupid's bow becomes less defined.
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.
No. They may get smaller with age, but not grow. As an adolescent reaches puberty, their lips may widen to match the growth of their jawbone, but the tissue will often soften and recede with age. Which is why rejuvenation of the lips is so popular with those in their middle ages.
Lip fillers for men are becoming increasingly common, with one news outlet reporting the “rise of the macho mouth” and a 74% increase in male patients requesting dermal fillers between 2015-2016. While men don't always want to feel more feminine, they can appreciate how great a fuller lip can look.
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.
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.
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.
According to experts, the best way to identify your lip type is by looking at a vanity mirror. If your top lip is more voluminous than your lower lip, it is a top-heavy lip type. Once you identify this, find ways to accentuate your bottom lip and balance the symmetry.
Research indicates that red lips are universally appealing, possibly due to a perceived association with sexual arousal. Highly attractive women were perceived as even more attractive in red.
