I was told no after shave or anything before treatments. It does interfere and could possibly cause problems. I used Aquaphor and pure aloe during treatments and came out mostly OK except for a few cracked skin areas and oozing of gunk . This cleared up a coupls of weeks later.

Since posting this. UPMC, Pittsburgh, Oct 2011 until Jan. I averaged about 2 to 3 surgeries a week there. w Can't have jaw made as bone is deteroriating steaily that is left in jaw. Mersa is to blame. Feeding tube . Had trach for 4mos. Got it out April.
