I'm curious about how to contour.

I've never tried contouring.

I don't know how to do makeup well, so even when I do, I just apply BB cream, draw my eyebrows, and put on lipstick.

It seems like people who are good at makeup can make it possible to achieve plastic surgery with it.

I want to try a makeup look that adds shading to my face without going overboard.

My jaw is a bit angular, so I've always envied oval-shaped faces. Is it possible to make my face look slimmer with makeup? I've never done it before, so I don't even know which brand to buy.

Please recommend some makeup products for contouring.
