While genetics and posture play a role in the “double chin” area, strengthening the underlying neck and jaw muscles can significantly improve skin firmness and facial contour.
1. The Rule of Thumb

Place a fist under your chin. Press your jaw down into the fist while using your neck muscles to resist the movement.
2. Tight-Lipped Smile

Tuck your lips over your teeth and stretch into a wide “toothless grin.” Feel the pull along the jawline.
3. The Tongue Trick

Tilt head back slightly. Stick your tongue out and try to reach toward your nose as far as comfortably possible.
4. Kiss Me (Neck Lift)

Tilt head toward the ceiling and pucker your lips. Imagine pulling your chin toward the sky.
