Greed-y for Urban Decay Primer Potions

Different eye shadow primers work according to personal preference and need. What is effective for one person may not necessarily be the answer for another. Personally, I consistently obtain great results from Urban Decay's Primer Potion range. Not only are they fantastic crease preventing and long wear bases, but they can be used on their own to add a quick wash of colour on the eye that will stay put. 

Urban Decay has certainly covered all their bases (pun completely intended) with the newest addition to the Primer Potion range-Greed. It is a true yellow gold metallic that has a surprising amount of pigment. It is very light reflective and the perfect companion for brown toned smokey eyes. It makes browns appear richer and magnifies any shimmer in layered shadows.

What is your favourite eye shadow primer? Do you prefer primers or cream shadows as bases?
