Facepulling is superior only in a situation where mouth size & head posture don't allow the tongue to comfortably push the palate with solid amount of mechanical force all day long. Once proper posterior tongue posture is possible, facepulling becomes redundant, except in the case where you tend to mouthbreathe on your sleep and want to keep making progress through the nights.
You think? Damn, I hope so, now a month and a half in serious mewing I can more confidently say that I can keep the posterior without much problems. But for real tho, as much as dangerous and ridiculous belt facepulling(considering we are at the topic of facepulling) came to be, it yields the best results I have seen, not only the maxilla comes forward and widens significantly with it, but it also goes up, like a lot. That asian dude and the other user in the forum which did it, widened their skull and shortened their face a lot, it was impressive, excluding the massive assymetry for which you dont even need a trained eye to notice, but no one addressed it, which it would be cool if that problem gets solved. Not that I dont see that tongue and chewing do it too, but like 2-3 millimeters if at all and havent seen by most people.
That slope I am talking about, I came to remember I saw in the lookism forum to be called ante face, however, they were talking about natural ante faces, like for example Andre 3000, he has significant ante face. Like, how does that even form, I mean by people of color I have seen it to be a natural thing and most have it, but by caucasians its not something that is usually seen and if seen its not much, but this mewing thing really causes it. The maxilla comes forward, the mandible comes forward a bit more and bam, the forehead misses it and stays back, but why, will originally the forehead be more forward if the maxilla was originally more forward, is everything really that connected? How does the bone grow for this to happen, I would be happy to have us a topic on that.
