When it comes to impulse beauty purchases, what's your biggest weakness?
For me, it's lip balms that have a unique fragrance/flavor. They're usually inexpensive, so I'm prone to impulse-purchases without giving them much thought. I'm also a sucker for a unique nail polish. If I spot something new at the drugstore that catches my eye and I don't think I have anything else like it in my stash, it usually ends up in my basket.
