OK, So highlighting your browbone is important, right? .. Yep, I think so too!
So, I have a few different eyeshadows I use as a highlighter, but I always come back to one in particular..
Rimmel Mono Eyeshadow [#244] In Moonstone.
I LOVE this shadow, It is a shimmering white shade, Acts as the perfect highligh, and reflects the light nicely. This is available in most make up stores for around £2.99. I highly reccomend it! I have been using this for a long time, and it lasts ages.
