You can't lose weight from one area, it's impossible without medical procedures. You have to lose it all over. You can use gua sha to help lymph drainage and some people find that helps their face looks slimmer
not really possible to lose face weight specifically without losing weight in other places since there aren't any work outs for your face (as ash said), but you can help by debloating your face, if you just look up techniques to help face bloating that might help
Guys off topic, but do ya'll have a routine to lose face fat
