IU (Lee Ji-eun) vs Jennifer Lopez

IU's facial proportions are consistently cited as near-ideal — upper, midface, and lower thirds in the golden proportion. This is her most consistently cited structural halo.

While proportionally excellent, her overall feature scale is small, which in some Western PSL frameworks rates slightly lower than larger-featured phenotypes at the same proportional quality.

Clear positive canthal tilt — approximately +3–5°. Consistent across decades.

Minor suspected procedure history but significantly less than peers. Current face maintains high structural integrity.
