Besides using Aquaphor for chafing, I've found three other things this stuff can be used for, which is a good thing, since I have a few sample sized ones and a large bottle at home.
1) Removes eye makeup - If you're wearing something else that is hard to rub off before running (primer makes it darn difficult/impossible), a little bit of Aquaphor makes it come right off.
2) Moisturizes lips - When I forget my chapstick and don't want to be running with dry lips, this scentless stuff does the trick.
3) Helps dry knees - Often, my knee gets incredibly dry at this one small spot. If I have the Aquaphor out for one of the other uses, I usually remember to use it for this purpose.
There you have it! So next time you get a little sample of this stuff in your running goodie bags, know that it will come to good use!!
