@gailmarienewton - my experience with Aquaphor was like putting petroleum jelly on your body. Since I had a double mastectomy I used a camisole to protect my clothing, but in the end that camisole was stained from the jelly, but I had no skin discoloration I have a medium tone to my skin so not sure if my skin tone masked any skin discoloration. But I used the Aquaphor religiously to prevent any possible skin issues. With the Aquaphor - a little goes a long way. I bought the larger item and could have definitely gotten by with a much smaller item. I also had 15 treatments - once a day for 3 weeks. I continued using the Aquaphor a short time after treatment ended - but I still have a lot of Aquaphor left.
