In an attempt to reconcile the doubters with the believers, I hope everyone will hear me out. Please see my threads from a few days ago to see that I'm both financially and emotionally invested in giving this treatment a shot myself.
I don't think yayapapaya is necessarily being a troll. He/she is a big skeptic about the whole dermarolling thing, even while still doing it themselves, and I think that's justified.
Numberguy (OP), while certainly coming across as sincere and helpful, has indeed attempted to benefit from the claimed success of this treatment. But I don't think that's wrong. His results are extraordinary and I don't personally fault him for selling the details about the treatment.
The facts are: we have a few studies that provide our scientific evidence. A skeptic could argue those were financially backed, because... well... at least the Indian study is demonstrably financially backed.
Reasonable skepticism should be both encouraged and is rational. I don't think it's insane to think that this particular treatment might not be as effective as everyone would like to believe.
And I'm a believer, for better or worse. But I'm also a realist. So I think we should all consider claims both for and against this new treatment with a grain of salt.
