The width of the lips should be about 40% of the width of the lower face and generally equal to the distance between the medial limbi. The width-to-height ratio of the face is typically 3:4, with an oval-shaped face being the aesthetic ideal.
Surprisingly, the research revealed that the participants preferred lips where the lower part was twice as big as the upper lip. They also found that the 'perfect' lips were 50 per cent larger than a the regular woman's natural lip size and took up roughly 10 per cent of the lower part of a woman's face.
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).
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.
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.
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).
Science has found that the most attractive lip shape has an upper-to-lower lip ratio of 1:2. Lips are most desirable in different shapes and forms for different people – 60% of people prefer a 1:1 ratio where the lips are completely symmetrical and evenly full.
He is looking at your lips
If his gaze keeps slipping down to your lips while he's talking to you, it's a sign that he is admiring you, fantasising about you and might even want to start a stable, long-term relationship with you," says Madan.
Full lips have long been desired by women because they signify youth and femininity. Evolutionary psychology also suggests that women with a full pout are often associated with a strong mating potential. One of the most visible signs of ageing is a pair of thin and flat lips.
First impressions count, especially when it comes to the laws of attraction. And as shallow as it might be, research reveals the facial feature men find most attractive on a woman: her lips. So when you meet someone new and notice his eyes, he's actually looking at your lips.
It's a common misconception that dermal filler is going to dramatically change your appearance with the very first treatment. In actual fact, 1ml of dermal filler is just enough to create a very subtle result that clients can then build upon over time (if that's your goal).
The average lip width was 50.98 ± 3.74 mm. The upper vermilion height was significantly lower than the lower vermilion height (5.9 ± 1.62 vs 11.15 ± 1.88 mm, P < 0.01). The lip obliquity angle was found to be 1.01° ± 0.73°.
The imaginary line from the base of the nose to the point of the chin was described by researchers from Kinkkale University in Turkey who recommended that ideally the upper lip should project 3.5mm and the lower lip 2 mm in front of that line.
Thin lips can be attractive, depending on the individual's preferences and facial features. They are often associated with a youthful and innocent appearance. They can also give the face a delicate, romantic look. Preferred by those looking for subtlety in their beauty.
The Differences Between Male and Female Lips
Men's lips tend to be thinner than women's lips, with fuller, plumper lips being associated with a more feminine look. The distance between the opening of the mouth and the base of the nose is usually longer in men, causing the male lip to appear “flatter” and thinner.
The person with bigger lips can kiss deep or passionate or lightly etc & it will have a specific silkiness that smaller lips don't have. I also find though that bigger lips can lead to messier or wetter kisses. Smaller lip kisses are firmer since there's less lip to make contact with & catch your kiss.
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. This can also lead to wrinkles around the lips.
When you're attracted to someone, your mouth produces extra saliva, Wood says. In response, he might quickly lick his lips or press them together.
Men also tended to look at a woman's chest and hip regions if they were showing romantic interest, which Bahns noted aligns with previous research that says this is due to men's evolutionary focus on women's ability to reproduce.
"We lick our lips in anticipation when we see something we desire," she says. That anticipation might even be making him feel uneasy. "When we get nervous, our saliva glands stop secreting, and our mouths get dry—leading to lip-licking," says body-language expert Patti Wood.
Full lips are the most common of shapes and are typically defined by lips that are equally plump on the top and bottom.
Heart-shaped lips
Heart-shaped lips are one of the most desired types of lips among makeup lovers. Pop star Taylor Swift is known for this romantic lip shape, which is identified by a well-defined Cupid's bow.
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.
Macrocheilia is defined as excessive lip size. Various ethnic groups share the characteristic of larger lips, including African-American and Asian (Fig. 11.21).
