Taking care of your makeup is fundamental. Why not carry out a weekly audit of your products? Take out anything that is broken or is missing a cap. Remember, you can decanter liquid foundation into a fresh container. The same, with creams and lipsticks; just transfer them into smaller containers. Place cap-less pencils in a zip-top plastic bag. Sadly, broken powder-blushes and press-powder are irreparable, and should be thrown away. A weekly routine is far easier than monthly / yearly overhauls.
