If you're talking about makeup, then I spend a lot but it lasts for over a year most of the time. If I'm in need of new makeup products I can spend $200 in an hour, but I only buy again after a year. As for facial washes, astringents, lotions, and other beauty creams, I spend about $100 per month on those. It's quite expensive actually now that I've computed it. But I have to have good skin right? And I do use products that aren't very expensive, so it's okay. I think the most expensive items I've purchased are acne medicine and acne treatments at my dermatologist. I spend over $100 on acne products/treatments per month!
