There was a recent post on this and someone recommended pentosan polysulfate cream. I can’t find this in a cream form on the web. Perhaps someone else could give it a try. About a year ago, someone posted here that he had excellent results with an over the counter cream marketed for skin discoloration. Unfortunately, I did not note the product name and I was unable to find the post. I have a particularly bad case of discoloration. The last time I stopped doing PE it took 6 months to disappear.
