He may be onto something and as mentioned in my previous post there are more groups involved in this study than just Dr Cot, lending greater credence to this research. I feel it has real potential.
I know many of us having been waiting for years some even decades for a cure and we've gotten jaded due to all the disappointment we've experienced, so you're right to be skeptical, but it's also good to keep an open-mind since you never know when they might actually succeed.
And the other benefit here is that it'll be used for skin regeneration. Those types of discoveries tend to be the best, when they're working on a cure for one ailment but then realize that it can be used to treat other diseases/disorders as well.
