How to rotate a certain area of a mesh (character lip)?

I want to make a character bites her lower lips. DAZ3d Genesis has no easy way to do it. So I want to sculpt it on blender.
But I can't find any tutorial showing how to rotate certain area of mesh (a lip).
How to do it?

I would rotate it in modelling.
Select one or more rows of faces on the lip, and then rotate with proportional editing enabled with a radius of maybe 2 cm, and set to connected only.
Blender is more powerful and stable, but perhaps you should consider learning Hexagon as well. It is designed to work with Daz Studio (easy import and export) and it works great at making small morph changes like you are describing.
Things to note: maker sure your model is zeored out when you send it over and back or strange things happen. Also, pay attention to the names as everything must stay the same for the morph to apply to the model when re-imported.
First, you can use FACS expression dials like Mouth / Jaw Open, Mouth Roll, Press, Purse, Shrug, Up / Down, etc.... or manipulate Lip sub-nodes under Lower Face Rig to easily get a "bite lip" expression. (like ss1)
Well, making it in Blender is doable but will be cumbersome, especially for the case of manipulating Lips (as well as Jaw, mouth cavity moving... etc.) no matter with Edit or Sculpt mode... because making such a "bite lower lip" is not a simple "lip rotation"....you need to do it with Mask while having to make other partial parts "staying" or "moving" naturally with this expression. Then after importing back to DS, you may also have to check rigging, corrective morphs as well... blah blah blah.
So better get to know FACS first of all, then try to well use them... At least you may dial some expressions first, fine-tune them in Blender and import delta back...rather than doing all from scratch. Then you'll get much better results, as well as pretty efficiently for sure.
Hemmm... I'll try.
