I've been collecting makeup for at least a solid 5 years. Perhaps longer but that's at least the amount of time I've been making beauty my job. I experiment a lot with various products and I have more than any one person needs, but that collection tour is for another day. Today, we're going through the small part of my stash which is currently at my vanity.
I try to go through this about once a month to rotate products I've tried, tested and shared my feedback on. Unless of course it's something I've absolutely loved and I can't part with it yet. I get a lot of questions about where those things go and the answer is that if it's something I love and want to keep, it's either in my vanity or in my makeup cabinet. If it doesn't work for me, it's given to friends. I love that my friends can come over and "shop" from my cabinets :)
