Hourglass Vol. 4 Ambient Lighting Edit Palette ($80.00 for 0.29 oz.) is a new, limited edition holiday offering that contains four existing shades and two new, exclusive shades (Filtered Bronze Light and Luminous Glow). The powders performed consistently with other Hourglass powders, so those who enjoy these palettes will likely enjoy this one, too, if the included shades work for your skin tone.
The palette contains $10.51 worth of Ambient Lighting Powder, $5.13 worth of Ambient Lighting Bronzer, $20.27 worth of Ambient Lighting Blush, and $9.50 worth of Metallic Strobe Lighting Powder for a total value of $45.41. If you expect to use most of the powders but don't usually finish products or often travel, it might be "worth" it to you, though typically palettes like these offer more for your money (since you are buying in "bulk" in a way) or else aren't nearly so drastic in the difference between value and price.
I bought this to try the formula of the powders before buying a full size. The face powder, bronzer and highlighters are very beautiful on the skin. But I don't really like the formula of the blushes. These powders are sheer and buildable with microshimmer. The shimmer isn't too visible applying the bronzer and the bronzer is buildable but the blushes are a bit too sheer. Because of the large amounts of shimmer in the blush I find it hard to get a good application. The blushes end up too shimmery on my cheeks before I'm able to build up the pigment. I like most of the powders but I wouldn't repurchase this or larger single blushes.
