Desitin is so thick, you don't really need to apply everyday unless the tear stain is really awful. For Linus, who gets into EVERYTHING, I usually apply every four days or so when his skin acts up and it sticks in there pretty good. Also, in terms of the powder of the face, I sometimes dust just a little over the Desitin to take away the sticky texture so no dirt gets stuck on it and have never had any problems using it. It also immediately improved the cosmetic look of the tear stains on white faces, which is a nice benefit. Here's a pic of Linus after his Desitin treatment...looks like he's ready for the beach!
