My favourite makeup product is a good highlighter, I love the dimension and glow it adds to the face. Recently I picked up the 'Strobe & Glow Highlight Kit' by MUA.
This cute little compact consist of a pearly gold powder highlight, and a strobing cream located underneath the powder. The strobing cream is more subtle so when applied to any areas of the face that catch that light such as your cheekbones, it gives a nice sheen rather than an iridescent highlight, which the powder gives. If you want full on blinding highlight apply the powder on top of the cream, it's very dramatic and not for everyone, but it certainly makes your cheekbones pop! I actually find this method increases the longevity of the highlight.
The only con for me is that it is on the pale side, I usually blend it out a little just so it isn't too intense and frosty. So if you have darker skin I would probably suggest staying clear of this one.
At £5 however, it's so no big loss for your bank balance so it's always worth a try and as always the product is linked below:
