If I'm honest I only bought the for the palette exclusive 'Incandescent light' as it is so gorgeous as a highlighter for the tops of the cheek bone and under the eye brow. It is the most natural highlighter for this purpose I have ever come across.
I didn't think I was going to like or use the other two shades 'dim light' and 'radiant light' but after talking to a girl at Mecca i decided to give them a shot.
Apparently dim light is good to use all of the face as a settling powder, personally I do not think it is good enough to use as a setting powder therefore I only ever use it on my cupids bow to define my lips and I do believe it does it nice job of this.
I do use radiant light over the top of my bonzer and I think it gives my skin a more natural glow which I love, it is extremely subtile so good for every day to day wear and harsh lights.
Overall I don't think i'd buy the palette again as I really only use incandescent light and I wish they would release it individually.
I did ALOT of reviews on this before adding it to my list. It took a Youtube vid from the amazing Wayne Goss to convince me I needed this in my life. It is expensive so I wanted to do my research first to see how it's best applied ect. Knowing abit about photography and how to use light to accentuate angles I was intrigued to see how these work. These powders give a beautiful, subtle glow to the skin. So finely milled they glad on the skin and with out feeling like an extra layer has been added. This palette essentially makes your face look like it is glowing from within. I use each of the individual powder for different area's of the face.
Tips: Dim light to set foundation, Radiant light as bronzer/ blush and Incandescent Light highlighting.
