Josie Maran illuminato
I have both products and they are great! You can use either product to highlight the planes of the face by forming a "C" shape from above the eyebrow to the tops of the cheeks just below the eyes. You can use either product to brighten up the eyes by putting them in the tear duct, under the arch of the brow, and by forming wiskers on the outer corners of the eyes (be sure to blend)
For my own use, I typically use High Beam to highlight the planes of my face over a sheer tinted moisturizer. I use Josie Maran underneath heavier makeup to brighten it up, or I will cut it with some foundation for an all over radiance.
Hope this helps!
