Hi Tarka,
I've also got ppp, tried various tablets and cream from the derm nothing has worked only suffered side affects and flare ups,
Since the end of August I decided just to use Dermol cream, my ppp is slowly clearing and I've had no flare ups, so keping fingers crossed especially for the next 3 weeks as I'm off on hols tomorrow,
Good luck with anything you try and let me know if you find anything that helps please, was going to try natural honey next if I get another flare just got to work out how to keep feet covered

Regards Maria
