Which ones? ; )
But seriously, this is a [Googleable question](https://www.google.com/search?q=What+are+lips+made+of). They are mostly skin, mucosal membrane, fat, muscle, connective tissues, and other things.
Any time you can make something move, you’re using a muscle to do it. And everyone has a bit of fat pretty much everywhere on them. And you need connective tissues such as tendons and ligaments to connect all that together.
