Because beauty products aren't always cheap, I like to get the most I can out of them. When I discovered this trick, I knew I had to share it with all of you.

Urban Decay Primer Potion ($15) is one of those cult-favorite products that people run through fairly quickly. But a few value-oriented makeup addicts have figured out a way to get the most out of the product. When the wand seems to have run out of product, they use an old knife to slice open the packaging, then scoop the primer into a different container. As you can see, there's a ton of product that you wouldn't be able to reach otherwise, effectively doubling the life span of this product.

It's surprisingly easy to do. Check out this guide to doing it yourself and enjoy the "extra" product you scoop out.
