What is contouring makeup that makes a big face look smaller?

For us Koreans, the ideal is a face that looks small and smooth, right?

I have a round face too, so I'm very interested in contouring makeup, but I usually just use blush to touch up the angular parts of my face and apply a little bit next to my nose.

Is there a way to do contouring makeup better?

I was watching Park Na-rae on *I Live Alone* before, and wow, she puts so much effort into contouring and takes a long time doing her makeup.

I only know how to roughly apply dark blush.

Please tell me how to do this well so I don't look like I have a big face.
