how is this different from a regular lip liner?Updated an hour ago

Trace It's sculpted, slanted tip has two working sides: a precision tip for sharp borders and a flat side for filling in, softening, or diffusing color. Trace It can line, contour, fill, and blur, all with a single tool. It's engineered with LineLock™ Precision Wear Technology to help grip the lip line and hold its shape, so definition doesn't shrink, feather, or settle into lip lines over time.
