Can mewing widen my face?

I am currently 20yo, ive noticed from old pics (18yo) that Ive recently gained more vertical facial growth making my face look thinner nar my jaw look less squared, ive had a pretty decent facial structure overall considering that ive never practiced mewing, my question is can mewing reverse vertical growth and widen my maxilla/jaw at this age? I’d appreciate advices on how to go about mewing and what can I realistically expect, thank you!
