The philium is the predominant lip shape feature that is often highlighted or outlined by lip makeup. The upper lip points or philium have ten distinct shapes and what they say about you is as unique as your personality.
The lip shape is defined by the lower and upper vermillion border of the lips. The vermillion border is the borderline separating the skin of the face below the nose and the vermillion zone of the upper lip. The shape of the upper vermillion lip border was found to have distinctive types, which are:
1. Twin peaks (V shape) – Creative
2. Uneven peaks – Sensitive
3. Cantilever bridge (flat line between peaks) – Inquisitive
4. Suspension bridge (U shape) – Outgoing
5. Double convex (two rounded peaks) – Flirtatious
6. Butterfly (softer V peaks)- Kind
7. Dome (single curve) – Outspoken
8. Flying bird (outer edge of peak tapers to corner) – Nurturing
9. Flat (no points) – Logical
In a study of lip shapes and genetic markers, researchers applied the method of high-resolution 3D imaging to test the potential genetic associations of lip and other facial variations. The researchers hoped to be able to predict genetic variations by facial shapes. This study was the first to provide strong evidence that the human gene rs642961 affects normal facial shape variation, which can be seen in individuals who have more protrusive and thicker lips. The human gene rs642961 is the same gene responsible for the cleft lip shape, which is often corrected by reconstructive cosmetic surgery.
