Is Chin Reduction Possible Without Touching the Bone- Tissue Only?

I do not like my chin at all. It sticks out and when I smile it makes me look like a whitch. By playing with the skin it seems as if if the skin/chin fat or whatever was tightened it would look better (I desire a more straight up and down chin instead of a chin that is a bump). Is there anyway fat or excess skin can be removed from my chin to achieve this (without shaving the bone).
