I was browsing in this forum and I heard about chin tucks, I heard that chin tucks everyday could help with jaw and chin projection by raising the hyoid bone and fix posture. So if it true it would be very good for me because my jaw and chin are just a little bit recessed they would look good if they were projected a little bit forward. Does what I said is true? Are chin tucks cope or not? Can chin tucks push the jaw area forward? How do chin tucks fix posture?
