How to "un-tuck" lower lip? (photos)

I received great feedback on my other question, but I would like to ask in a bit more detail what I'm looking to do with my lips. The bottom lip seems very "tucked in", almost quivering. Note how the border beneath my lower lip seems to disappear towards the center and isnt that normal 'U' shape. Now note the 'M' shaped upper lip. For the upper lip I would like a more conservative augmentation, simply to straighten out the line created where the lips meet. I attached an edited before and after.
