While some of my research suggests using baby oil to create a "wet look" eye shadow, I found it collected in my eye lid crease almost immediately. But if you're trying to create a high-fashion look for a photo shoot or other quickie event, it'll work in a pinch. Check out this DIY tutorial to see for yourself.

If you want to completely scrap your eye shadow, you can turn it into nail polish just by adding clear nail polish to the powder. I recommend mixing the polish and the shadow outside of the bottle and storing it in an airtight container, so you don't use an entire bottle of clear nail polish on one eye shadow color. We tried mixing our own polishes over at Beauty Riot -- click to see what crazy colors we came up with.

Problem: The nail polish color that you just have to have on your toes right now is locked away in a bottle that won't budge.

Solution: Rubber Band

If you're having trouble opening a nail polish bottle, wrap rubber bands around the top for a better grip. If this doesn't loosen it, try dabbing some nail polish remover around the brush handle.

Problem: I've never gotten to the bottom of a nail polish bottle, so my nail polish collection just keeps growing over the years. The only time I throw a bottle away is when it becomes clumpy and coagulated, making it impossible to smoothly lacquer over my nails.

Solution: Nail Polish Thinner/Remover

The next time your favorite nail polish goes all cottage cheese on you, try adding nail polish thinner. You can pick it up at Sally Beauty Supply for $4.29.

The quick fix? Add in a little nail polish remover. Keep in mind that the high water content of the remover will cause polish to separate over a long period of time, but if you're planning on tossing it soon anyway, it's a good temporary solution.

Problem: On a hot summer day, your makeup tends to slide right off your face. The same thing can happen to makeup that's been left sitting out in the sun.

Solution: A New Container

If your lipstick has been rendered un-wearable by the elements, scoop it out of its container and transfer it to a small pot, like this or this from The Container Store. This also applies if you, like me, like to get every last drop out of that $34 lipstick, but the product is too far down in the tube. Use a toothpick or q-tip to scoop it out.
