This weekend, I have vowed to go through my makeup and throw out the stuff I never use. How long does makeup last? I have some eye shadows and lip glosses for a while, no idea when I got them. How do I know if they have gone bad? I have a really nice closet in my bathroom that has a lot of shelves. So I am thinking I am going to arrange my products on the shelves. Does anyone have any recommendations for containers and other organizational items I can use to transform my makeup and skincare closet?
