[Face] Will just one type of contour (cheekbones) cause sagging skin and a double chin??

I'm a man in my early 20s. I've been having a complex about my cheekbones since I was young, so I'm thinking about getting surgery these days, and I 'm worried about sagging weight. Even now, I hear people say I'm warm, but I do n't know much because I feel like I'm going to be bad for no reason, but please give me some advice, everyone! If I don't do 3 types of contouring and only do cheekbones, will I lose less weight?
