Im 17, my jawline is terrible. Ive started to do those chin tucks and neck curls shit you see on tik tok, but like idk if its cope or not. Anyone got any tips or anything i genuinely need help so bad. Ima get mouth tape soon, as ive noticed i sleep with my mouth open a lot. Thing is im pretty fit and go to the gym regularly, so idk if losing fat is the move. Ill do mostly anything to fix it (no peps or anything), so if anyone got some actual proven methods it would help. My chin is also very recessed, so that is a problem too. Any help would be appreciated.
