So I have done a few bad makeup science experiments before with my own nude lipsticks, foundations, eyeshadows, liquid lipsticks, and highlighters, but I wanted to think bigger this time, and go outside of my own makeup box to see what insights on Sephora I could get by melting one of every lipstick they carry in their store. So we melted 603 lipsticks from 20 different brands, and made 500 to send to you all!
