When I first starting doing make up I had never heard of contouring or highlighting and we were just happy with a bit of blusher but over the last few years it's a big deal. I am not the best at giving myself cheekbones and have always thought of myself as having a moon face but a good contour pallete can really help with this.

The first one I ever bought was the Maybelline master sculpt one and that to me is one of the best around. It comes with a little brush which I did use at the start but after some practice it's better with a different brush. A perfect tip for contour is smile and put a pen on the lower cheek bone at an angle and use your brush to go along side the pen for a perfect line and then blend ( I use a blending sponge to blend but I'm sure the brush would work as well)I found this hack on you tube and find it works a treat and it works perfectly with the Maybelline.
The collection one is pretty similar to the Maybelline but you get more product and it's £3.99. So a much better budget buy.
For highlighting I love the radiance palette from Revolution.. I do love a revolution palette and this one is so good for highlighting.
It comes in 3 shades so there is 3 looks in one with this one wheather you want a more bronzed look when you have a tan or for more of a normal highlighted finish. I find they all work on my skin but there are a few variations of this palette or definitely worth a try next time you are in a larger Superdrug store.
I said earlier that a good bronzer can make an effective contour I find this really is a good tip to know just in case you don't have a contour palette or just want to have a go before commitment. It's all about trial and error and there are many tutorials on the internet that will show you just where to apply but the pen hack is definitely one to try.
You also don't have to spend a fortune on brushes. I find the Primark ones are excellent and as good as the Real Technique ones.
