Eyelid Crease Formation Quiz

Foundational understanding. Focuses on puffiness, crease stability, repeatability, and the difference between a temporary fold and a naturally returning crease.

Tests whether you understood skin tension lines, mechanotransduction, controlled repetition, and why real crease stability depends on consistent mechanical input.

Deep mechanical reasoning. Covers inverse folding, structural memory, fold footprint, cumulative adaptation, and why autonomous crease return is different from surface-only cosmetic folding.
