Bone structure
Face Slapping / 'Slap Facials'
Bonesmashing's softer sibling. The flush is inflammation, and the underlying claim — that impact builds facial bone — is the same wrong one.
Also called: slapping facial · face slap massage
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
Repeated impact causes vasodilation and low-grade inflammatory oedema. Bone adapts to sustained functional loading, not to percussive trauma, so no osteogenic pathway is engaged.

The full read
Sold as a circulation treatment, it inherits the failure of bonesmashing: the mechanism people imagine (microtrauma → bone remodelling) describes load-bearing compression over years, not slapping. What it does deliver is a genuine post-inflammatory flush that photographs well for an hour. Repeated over months, chronic low-grade inflammation is associated with pigmentation in darker skin types and does no favours to a compromised barrier.
