That's a really good question. I don't contour. I have high cheek bones and find contouring makes them look worse. I use blusher or bronzer instead. I suppose you need to see which part of your face needs defining, if any.
Start of light and little, make sure you work out your face shape, dont just go on any tutorials you see as it can look wrong if you dont have the same shaped face… i prefer not to contour using creamy products i like to use powder. I find a light bronzer that is matte no shimmer and a white setting powder stops you looking like you have a dirty face🥰🌹
