Now I know everyone loves Urban Decay Primer Potion, and its popularity prompted Urban Decay to introduce a new formulation in a champagne color - Sin. It a tinted, shimmy version of their regular primer potion. Most have said that Sin works best with shimmery frosty based shadows. Urban Decays claims with this product that it:
"Urban Decay Eyeshadow Primer Potion - Sin combines incredible staying power with a shimmering champagne hue that complements almost any eyeshadow. This two-in-one beauty miracle can be worn alone to give eyes just a hint of tint for when you're in a hurry or in need of that "no makeup" look."
"It also makes a great highlighter: apply from lash line to crease and then apply your shadow on the lid only."
