(also, please excuse my blotchy skin- my final exam is tomorrow! The stress is not doing my skin any favours)
If you've been looking for a really affordable drugstore product to contour your face with then Collection Shimmer Shades is a product that should be on your radar. There are four shades, all of which I'm going to describe in relation to my skin tone- there's a very light contour (perfect on very pale skin), a medium contour (perfect for a more dramatic contour on pale skin), a dark contour (unwearable as such for me, but great for me as an eye shadow) and a peach blush which is gorgeous used with the contour shades or alone.
I have fallen in love with two of the shades, the lightest contour and the peach blush! Together they work absolutely perfectly to shape my face whilst still being really subtle. I think as my skin gets a little bit more colour over the summer I can start wearing the medium contour shade more often. At the moment it looks a little bit stark if I wear it during the day but is great when buffed out to look more subtle and worn in the evenings. I can't make the darkest contour shade work on my skin, but I've worn this on my eyelids a few times and with a primer it lasts all day. On my cheeks I can apply the contour and blush in the morning and when I get home in the evening it's still going strong on my cheeks. The longevity of the product is fantastic!
Also, because there's a choice of shades it makes it perfect for a rage of skintones, so if you're not as pale as me don't worry! The medium contour is likely to work well for you (it isn't at all orange!) and if you're a lot less pale then the darkest contour might just be perfect for you! You could then use the lightest or medium contours as base colours for your eye lids. All in all, I think it's a really great product because it will work for so many people in a lot of different ways.
