Girly Girl Moment #1
I LOVE Urban Decay Eye Shadow Primer Potion. Here's why...your shadow really does stay on all day (barring a bout of "ugly crying"...in that case, nothing is gonna keep your makeup on, but in my experience, when "ugly crying" you simply don't care about makeup).
I have used this product for 2 years and have found that in the long run it saves me money. It transforms my cheap eyeshadow into a long lasting higher end version. I've used other primers only to find them cakey and weird. Primer Potion is smooth and for lack of a better word, it really is potion-esque.
I get mine at Ulta (where sometimes you can find a 2 pack at a better rate), and Sephora.com sells it too.
