I'm really debating getting this device! I've watched about a million videos on it. I guess I still have some questions about it. For example, the protocol calls for once every two weeks. But isn't this kind of like a form of needling where you would only want to do it once every 4 weeks? Especially because its deeper than 0.5mm? Somebody shed some light on this for me if you can, I don't want to disrupt my collagen cycle.
