The formula of this is really soft and buttery, and it applies nicely with a brush. However, it is just too light for me to use as a highlighter with my medium skintone. I am currently using it as a browbone highlight, since I don't like a shimmer or frost there - I will never run out!
I've also seen others use this as an underage setting powder for concealer, and I find it horrendous for that purpose. With a brush, it emphasizes pores I didn't even know I had there, and with a damp Beauty Blender, it looks cakey and powdery.
I do think this is a good quality product for fair - light skintones, but if you are deeper, it might not work.
