I am an avid user of Desitin diaper rash cream, have been for years since I started working at a daycare. However, the original formula had that awful fish smell to it, which I put up with because it worked so well. Now, they have a new version out, the Desitin Creamy, which is a bit less thick than the original, and has no fish smell!!
Let me tell you, I am in love. I use this for everything, not just diaper rash, hence why I entered it in this category. I use it on my baby's fat rolls ro prevent chafing (hee hee); I use it on my thighs to heal chafing after running; there are so many uses for it, and all without that icky fishy smell! I did rate it a little low in the fragrance/oil free category simply because it does contain mineral oil and petrolatum, which some people do not like to put on their babies.
I highly recommend Desitin Creamy to anyone who is looking for a diaper rash ointment.
