Jawline
The jawline defines the lower face contour from ear to chin. Its angle, width, and definition strongly influence face shape classification and perceived masculinity or femininity in AI facial analysis.
Chin
Chin projection, width, and shape define the lower face terminus. Pointed chins characterise heart faces; wide chins suggest square or triangle shapes; recessed chins affect profile balance.
Skin Quality
Skin texture, tone evenness, and luminosity influence perceived age and vitality in AI analysis. While not a geometric landmark, skin signals feed youthful-energy scoring and overall impression.
FAQ — Neck & Jaw-Neck Transition
What is a defined jaw-neck line?
A sharp transition from jaw to neck with minimal submental fullness, typically associated with a cervicomental angle near 90–105 degrees.
Does neck skin affect age estimation?
Yes. Neck laxity, horizontal lines, and submental fullness are age signals often weighted in AI models.
Can posture improve neck appearance in photos?
Slightly extending the neck and aligning the chin forward creates a cleaner jaw-neck line in portraits.
