What can I do to my lower face to make it more angular and v shaped and more structured? (Photo)

You could try filler first. If you want more dramatic results, you will need jaw surgery to actually change your anatomy. Liposuction is not an option. You have a beautiful face now and I suggest leaving it alone.

Dear amandasilvat,
it is hard to tell for sure without an examination. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

Each individuals persons facial appearance is almost exclusively derived based on bone structure. Soft tissues tend to be very consistent from person to person and the differences between each unique person‘s facial appearance with the exception of facial aging is bone structure.Soft tissue manipulation is not addressing the primary problem and can have some positive effects but to properly change facial structure should be done by addressing the primary bone structure.
You can try Massinger Botox if you want. perhaps you may like the outcome.
I think your facial structures are good and overall attractive so I would not mess with that too much in regards to permanent and irreversible treatments..
Best,
