Korean Attractiveness Test (2026)

Lower-Face Width (V-line geometry)

Lower-face width below cheekbone width — the V-line — is the most cited single trait in Korean aesthetic-medicine literature. The metric reads zygion-to-gonion ratio; the score is sensitive to chin-down camera angle.

Face Length-to-Width Ratio (Small Face)

The 'small face' (소얼굴) ratio — face proportionally smaller relative to head — is a recurring reference in Korean beauty studies. The metric uses face-bound to head-bound ratio when both are visible in frame; otherwise it falls back to face length-to-width with a different weighting.

Midface Ratio

Korean aesthetic references favor a shorter midface (philtrum-to-eyeline distance proportionally smaller). The audit reads this as a higher midface ratio score; the metric is photo-angle-sensitive in the same way the V-line metric is.

Eye Spacing & Aperture

Korean beauty literature describes a preference for wider-set, larger-aperture eyes. Our metric reads interpupillary distance normalized by face width — the score is intrinsic to geometry, not influenced by makeup.

Skin Quality (texture + tone uniformity)

Korean beauty discourse emphasises 'glass skin' (유리 피부) — uniform tone, smooth texture, even reflectance. Our skin-quality metric reads exactly this profile. Soft window light reads truer than ring-light, which often introduces uniform highlight that fakes the reading.

Top-band scores against this reference indicate the photo aligns closely with multiple Korean aesthetic markers simultaneously — V-line geometry, small-face ratio, even skin reading. This is a high-conformance reading; it does not mean a higher absolute attractiveness score, only a closer alignment to one specific cultural framework.

High-band scores indicate alignment on most Korean aesthetic markers but a drag on one — often the lower-face width metric, which is sensitive to camera angle. A retake with the chin tucked slightly inward typically lifts this metric several points without any structural change.

Mid-band scores often reflect a non-Korean photo angle (camera below chin, head tilted, ring-light front) rather than divergence from the reference geometry. The audit retake guidance focuses on framing and lighting, not on features.

Low-band scores against the Korean reference are not a 'low attractiveness' reading — they indicate the photo geometry diverges from this one specific cultural framework. Different cultural references would yield different score patterns on the same photo.
