Hourglass Diffused Light Ambient Lighting Powder ($45.00 for 0.35 oz.) is described as a “soft, warm pale yellow powder.” It’s a pale, pale white with subtle yellow undertones and a barely-there sheen. This one didn’t have any sparkle or shimmer. I’m not an expert on finishing powders, as I’ve only tried a dozen or so on the market, but you can see my past reviews, which may be helpful. From what I’ve tried, I felt like MAC’s Sheer Mystery Powder may have been the most similar in terms of feel, look, and composition (pressed, soft, no sparkle), but I wouldn’t say they’re dupes for each other.
