Pinxav....some may have heard of it some may have not but it's been around since before Desitin...and it works almost instantly.... I buy it at Wal-Mart and such....a lot of times you have to go over to the pharmacy and just ask them for it because it's OTC but they don't always put on the shelf...best diaper rash product by far....and I have tried them all and all the others ended up in the trash...
