I’ve got 3 types of UDPP and what I love about Sin is that it’s so versatile. It can be worn along as a long-lasting eye brightening shadow and it just looks so fresh and pretty (provided you don’t overdo it). Even better, using it under shadows like MAC Tempting (beautiful in the pan but less so when applied) really brings out the beauty that is usually lost when these types of shadows are applied. Great product. And I might be weird, but I like my old Genie bottle with the bent doe-foot. Seems to dry out far less quickly than in the squeeze tube.
