Will widening the jaw help me achieve more masculine features?

What makes you think that you don’t look masculine enough? You certainly look like a man. It’s not always about the appearance. What represents masculinity of an individual is mostly about certainty and the behavior of an individual. Of course, if you desire to have a more square jaw, it can be created for you. There are a lot of different fillers which can be used just for such a reason and this way you can decide if this is something that you like and something that you wanted it. I hope this helps and good luck from New York City Plastic Surgery.
