Hi I'm a 22 year old guy. I've watched Youtube videos of doctors using filler for male facial sculpting and seems to have very good results for a little bit of filler. Is it possible to attain the same results but using fat grafting? I'm not looking to change the shape or size of my jawline or chin but rather make it more defined. Specifically is it possible to make the masseter area sharper / have the skin wrap around the masseter much clearly?
