I am self conscious of my profile at times when I am laughing or smiling too hard- I feel as though my chin disappears into my neck (yes the picture I attached is a bit exaggerated but you can see what I mean). I am a rather petite girl so I should not have too much fat under my chin, yet I feel like I do? Would chin filler or jaw filler enhance my lack of facial structure/reduce the appearance of a "double chin"?
