How to Get a Bigger, More Masculine Face?

I am a man with a very small face. I look like a little kid in pictures, due to the actual size of the whole face, it is narrow and thin. I believe a small face is due to a deficient lower jaw. I really do not wish to get jaw implants due to bone erosion etc. I have considered stuff like PMMA injections into the jaw to make my face bigger and manlier, what are the alternatives to jaw implants? I only want alternatives that will bring a huge noticeable change in terms of size of the face.
