I bought this after trying pretty much everything else known to mankind to help with my daughter's horrific diaper rash. I was told by numerous people including our Ped. that this was the best stuff. Well maybe my daughter is resilient to zinc oxide, the active ingredient, but it didn't work that well on here. Yes it kept wetness away from her skin and it did leave a good layer on her for protection, but it did not get rid of her rash. I used it until there was nothing left and she still had a rash. The only thing it did was help with the rash getting worse, but it did not heal it like I thought. Performance It helped make the rash worse and it did keep wetness off her skin but it did not really help her diaper rash like I expected. My daughter does have very sensitive skin though.
