What are the anatomical and aesthetic differences between permanent dipliner and eyeliner?

Permanent Dipliner, also known as lash line effect, is applied as a very thin line only within the lowest lash line, filling in any lash gaps; a wing is never extended outwards. The aim is not to create a made-up look, but to make lashes appear fuller, eyes more defined, and the gaze deeper, all while looking completely natural. In permanent eyeliner, a thicker line is drawn above the lash line on the upper eyelid, and a distinct “wing” is extended upwards from the outer corner of the eye; this is a full-faced look and is applied to those who are willing to wear eyeliner constantly in their daily lives.
