Some products which I think I do not use as much as I should are the Face Of Australia Mineral Therapy Illuminator in Angel Mist and Angel Blush. I do believe these are similar to the Becca Shimmering Skin Perfector's, but y'know, cheaper, at $14.95 rather than an approximate $65. The only minus I have on these are the packaging. As you can see, the liquid comes in a squeeze tube bottle, which gets very messy and annoying fast. That's probably why I don't use them much. If they came in bottles with a pump or something my rating for these would skyrocket.
As you can see in the pictures, a little bit of product really goes a long way so these will last me forever. The liquid also has not broken me out or messed around after a long day of wear. They do come in two other shades: a pinker version of Angel Blush, Angel Flame, and a golden-topaz one called Angel Glow. I did have Angel Glow when I was doing my photo shoots, but I found that it was too pigmented and strong for light skin and in turn would work amazingly on medium-tan to deep skin tones for a lovely bronze glow.
Overall, I really like these iluminators, even though I do prefer powder highlighters over liquid.
