Firegoat Rolls, they are a great way to remove discolouration, its best to use them after PE, if you hve been pumping or any type of extreme PE, then they work.
For more long term colour, you could try a skin peel, but its risky. There is a lot of information online about that, and we will make a thread here to explain how its done. It removes a layer almost like a snake shedding. But try some FGR for now, and see if that helps.
