With the high cost of cosmetics, I have discovered a way to use ALL of your lipstick! When the tube gets flat on the top, I use a plastic cuticle tool to dig out the remaining lipstick.
There is a lot of lipstick left after it becomes level with the container. Just use a sponge tip brush and you will get many more uses.
My tip is for being able to use the last of lipstick tubes. You take a pill box that is labeled for the days of the week. Then you dig out the last remnants of the tubes of lipstick and you put one color per compartment.
If you're running low on lipstick, or looking for another shade, but hating those big-bucks prices, try applying foundation and a little moisturizer, lip balm, or cocoa butter onto your lips before adding your lipstick.
Save money on lipstick by using the lip color pencil to outline your lips, then use it to fill in the lips with the pencil. The color stays.
