When considering a lip lift, understanding lip types is crucial. "Curtain lips" are thin, tight, and dense, resembling how a curtain moves straight up when pulled.

These lips have more tooth show but limited red lip enhancement. A simple lip lift may not suffice, often requiring additional procedures like a VY plasty.

In contrast, "Carpet lips" are fuller and softer, similar to a rolling-out carpet. These lips respond well to lip lifts, increasing both the Vermilion height and tooth show, making them ideal candidates for a straightforward procedure.
