The controversy has resurfaced in France in recent weeks. The American streamer Clavicular made a stop in Paris, where he was completely ignored by the Parisian women he approached on the street. He became famous for his "bone-smashing" method, which consists of hitting one's face, especially the jaw and cheekbones, with a hard object, sometimes a hammer, to "sculpt" more "square," more "masculine" features. His rationale is based on bone healing, which he completely misuses. Those who practice this often rely on a misinterpretation of the ability of bones to remodel themselves under certain mechanical stresses, a real phenomenon, but one that doesn't apply in this way to the facial bones of adults. Behind the pseudo-scientific vocabulary, doctors are sounding the alarm.
“From an anatomical point of view, not much is happening, nothing at all in fact, that’s the problem.”, explains to Science and Future Dr. Serge Ketoff, maxillofacial surgeon and stomatologist, practicing in Paris. “It has no effect on bone growth.”
