Chin Straps / Jaw Slimming Bands
Elastic compression leaves an indentation that fades in under an hour. Worn overnight it can push the mandible into a retruded position.

Verdict — cope
The mechanism does not hold. Your time is better spent elsewhere.
Evidence grade D
Nobody has demonstrated this works. Note that this grades the evidence, not the danger — read the verdict for that.
Mechanism
Sustained elastic pressure temporarily displaces interstitial fluid from submental tissue. It applies no force capable of changing bone, and no mechanism reduces adipose tissue through external compression.

The full read
Spot-reduction of fat by compression is not a thing — the fat is not squeezed anywhere, and the visible tightening is oedema redistribution that reverses on standing. The real concern is directional: a strap that pulls the mandible up and back loads the temporomandibular joint in retrusion for eight hours a night, which is the opposite of the position most jaw pain protocols aim for. Submental fullness that survives leanness is usually a platysma or a hyoid-position issue, and those have real consultations attached, not a €12 band.
