If you have a double chin and you're not overweight — read this. There's a muscle in the back of your neck called the SCM. When it gets locked from looking at your phone all day, it pushes your head forward. That compresses all the tissue under your chin into a pouch. It looks like fat but it's actually just bunched up tissue from bad posture. Hizoo's four kneading nodes plus 42° heat releases that SCM. Your head goes back. The tissue under your chin stops bunching. The double chin goes away without losing a single pound.
Not enough history yet to show a trend.
