i don't get here very often, so i'm hoping that you figured out how to use the VE and have seen a end to your PD. in the chance you haven't, you can't use too much VE. just put the VE dirrectly on your skin. around your mouth , nose, eyes. where ever your having the problem. everytime i would want to scratch, or rub my face i would put some on. after it's gone away,if a bump, that may, or may not be PD appears just put some more on and it's gone before it can get started again. please email me let me know how it works for you and if you have any questions. cmercier@wbcable.net
