How to get a sharper jawline: 7 steps.

Why jaw definition changes

How defined your jaw looks depends on bone structure, facial fat and soft tissue. You cannot change bone with a routine, but you can change the rest. Research on facial adiposity links leaner faces to healthier-looking ratings (Coetzee et al., 2009), and a JAMA Dermatology study found facial exercise improved cheek fullness over 20 weeks (Alam et al., 2018).

The 7 steps

1. Measure first. Scan your face in Hexum to get your jawline score, gonial angle and baseline Overall Score.
2. Get leaner. A modest, steady calorie deficit with high protein is the main lever for facial definition.
3. Sleep 7 to 9 hours. Poor sleep makes faces look puffier and more tired (Axelsson et al., 2010).
4. Fix posture. Pull your chin back and keep your head level. Forward head posture hides the jaw.
5. Control sodium and alcohol to cut day-to-day puffiness.
6. Do 10 minutes of facial work daily, as in our facial exercise guide.
7. Rescan weekly in identical lighting and compare your jawline score.

Do it with Hexum

Hexum builds steps 1 to 7 into a daily protocol of about 38 minutes. Hexum users average a +35% improvement in Overall Score from first scan to week 6.^*
