Oh Silver, you're going to look fantastic in that dress! I love Honey's suggestion of Lucidity for you. Definitely check it out, I've used a similar product and it's very user-friendly!
Dial soap is horrible for your face!!! Good ditto on the Cetaphil, I've used it for a couple of years now and have been pleased. It comes in a regular (blue label) and sensitive skin (green label) formulation.
You WON a dermotologist peel? Silly girl, go on and make the appointment
Of course, tell them about your skin issues up front in case they recommend something other than a peel in your situation (and of course apply the peel credit to the treatment they suggest!)
