In this tutorial I am going to show you how to make human lips. The reasoning for making it is that I have noticed a lot of people are having trouble making lips. They have a very complex form; both the upper and lower lip feature very complex curves that bend on the 3 axis. This causes another issue that makes modelling lips harder; the skin and the lips meet and intertwine in a very complex way thus making it very difficult to model the end of one and the beginning of the other. This might be an issue when making a very high detailed model (when you use ZBrush or Mudbox) and you end up adding details to the wrong part.
