At 20 months my son broke out in a horrible horrible rash, I think a combination of teething, wind, and allergies. I went home and put Lanolin cream on it and it was gone the next day. That was after 3 days of trying vasoline and Aquaphor, with absolutely no improvement. Its a little hard because its so thick, but if you massage the tube (to warm it) it gets a lot thinner like aquaphor--i was definitely glad I tried it.
I've been dealing with a horrible cold/sinus thing started getting dry red chapped skin under my nose, put some of that on it and it cleared up have kept it on and haven't had any problems since.
