Will Weight Loss Alter The Look Of My Chin Implant?

I had a chin augmentation surgery (with a button chin implant) to enhance my femininity. However, I still think my chin is not pointy enough on my frontal view. I’m planning to go through a rigorous weight loss program (losing 30+ lbs), and I wonder the following: a) could there be any fat tissue between the chin implant and the skin, and b) if so, can the fat tissue be reduced after a significant weight loss? Thank you.
