Understanding Canthal Tilt: Positive vs Negative Palpebral Angles

Canthal tilt describes the angle formed by drawing a line from the medial canthus (inner eye corner) to the lateral canthus (outer eye corner) relative to the horizontal pupillary line.

Canthal tilt is the angle between the inner and outer corners of the eye. A positive tilt (+2° to +6°) is associated with youthfulness and vitality, while negative or neutral tilts create different aesthetic perceptions. Full guide coming soon.

⚖️ SAGITTAL BILATERAL

Bilateral Facial Symmetry: What 68 Landmark Points Reveal

Evolutionary biologists note that bilateral symmetry is one of the strongest cues in mate selection, signaling developmental stability and immune fitness.

Bilateral symmetry is one of the strongest cues in facial attractiveness. High-harmony faces typically show under 2.5% lateral variance across the sagittal midline. Full guide coming soon.

📐 MANDIBULAR RAMUS

Mandibular Cephalometry: Defining the Ideal Gonial Angle

The gonial angle (the angle formed between the posterior border of the mandibular ramus and the inferior border of the mandibular body) determines jawline sharpness and neck-to-jaw transition.

The gonial angle determines jawline sharpness. Ideal range is 118°–124° for masculine definition and 122°–128° for feminine curves. Full guide coming soon.

💎 ZYGOMATIC ARCH

Bizygomatic Prominence & The Compact Midface Ratio

High cheekbones create the coveted aesthetic "ogee curve" of the midface, framing the eyes and providing natural structural support to preventing midface descent.

High cheekbones create the "ogee curve" of the midface. A compact midface ratio approaching 1:1 is scored higher for perceived youthfulness. Full guide coming soon.
