Bronzer is my bff. It puts life into my face. It helps conceal the fact that my foundation is too light. Once in a blue moon it sculpts the ish out of my face. If you're being creative, it also serves as a great transition color. Let's here all about Nars' Laguna bronzer.
The Bad: It's not as pigmented as I like and I prefer a bit warmer of a bronzer. I just got this because I gave into the cult hype.
The Good: Since it's not crazy pigmented, it blends great and is buildable. I can see this being a great contour color if I could ever bother.
Overall, I say trial size is best to see what purpose this color can give you.
