Neck and slight jawline lipo back in 2011 at 30 y.o. bc of genetic issues - now I have this bulge - what can I do? (Photo)

This bulge is excess skin and sits like this bc of the lipo (I had a fuller face in my 20s) and it slightly sags. It's only be an issue on the right side and is prominent in certain lighting, movements / positioning and people have commented that it looks like I have something in my mouth when I do not. I know that bc of my mom's face that I will need a neck lift at some point bc of skin laxity, but I am only 40 and want to know what I can do to minimize this before then.
