So now with watching this video, I'm still not really a fan of the machine. Not that I may feel pain, but I could buy something more fun, maybe. With that said, is it the suction that makes the injector important for the products used? If thats the case, why not consume the glutathione? Some skin care is better consumed vs applied and vise versa. I try to be conservative when purchasing tools. So I don't have equipment i never use.
