Canucker~~I am in almost the exact same position as you--only Accutane worked years ago, and now with trying for family not able to take any medications.
I'm in the preliminary stages, but I found something that's working quite well. It's a product line called Dermalogica. I use the Anti-Bacteria Wash on problem spots, and then they have a calming wash for the rest of my face. I've used it now for about two weeks and my face is completely clear and back to normal.
I know there are several places to purchase in Hong Kong, but I bought mine from back home. If you do a Search of Dermalogica on here, it brings up a thread someone wrote a couple months ago with several suggestions of places to purchase.
Good luck to you and if you choose to try it, I hope it works as well for you as it did for me.
