Diaper-Rash Cream
Standard use: Clearing up rashes and redness on your baby's bottom.

Surprise use: Protecting yourself from sunburn.

Desitin contains about 20 percent zinc oxide, which is also a nonirritating physical sunblock, says Mantione. But as moms know, this paste goes on white and doesn't absorb into the skin, so it's best used when you've run out of sunscreen and don't mind looking like an ’80s lifeguard.
