How can I fix my Submental Cervical Angle?

[deformedTG]

My submental cervical angle is terrible

~ 135 degrees (measured this shit on faceiqlabs so it’s very inaccurate, it read my clavicle as my neck but it wasn’t too far off in the picture I took though)

One of my worst features by far lmfao

Not to hate but one google will probably tell you. Maybe look thru more populated forums for a guide but that’s about all I know
