My son has the same thing. It is dry skin. He has excema. Hydrocortizone cream did not work for him. But I started using unscented everything. The best baby wash is Aveno extra creamy baby wash, it is wonderful and started helping his skin right away. I also use the Aveno baby lotion or Eucerin calming cream. I like the Aveno better though because it is not greasy. I use it all the time now instead of regular baby lotion and he very rarely breaks out in a rash anymore, usually only if he is exposed to something that irritates his skin.
