These Were the 15 Hottest New Beauty Products of 2015

The product: Urban Decay x Gwen Stefani Eye Shadow Palette ($58)

Why we want it: Gwen Stefani was one of the first celebrities to support Urban Decay nearly 20 years ago, and her love for the brand has been rewarded! This collaboration palette features 15 gorgeous shades — 12 of them new — that Gwen helped create, because the colors she wanted were missing from her current makeup stash.
