The only reason I could see water hurting would be if it prevents or slows the lotion/creme from being absorbed into the skin.

Otherwise, I wouldn't see any issue but I'm no RO. Definitely something to check out with your doctor.

On the original question, I used aquaphor 2x per day and I didn't have terrible issues with my neck. I also made sure to stop using abrasive/drying soaps and face washes. I purchased cetaphil bar soap and used that throughout treatment.
