Please recommend a contouring product that is perfect for cool-toned skin!

I have bright, cool-toned skin, around shade 17 to 19.

I have a complex about always looking wide and chubby because my skin tone is light and my features are indistinct.

So, the part I put the most effort into when doing my makeup is contouring.

I still haven't found a contouring product that looks natural and doesn't look artificial.

I use the Etude Single Shadow in Lady Earl Grey the most because it looks so natural and pretty, just like a real shadow.

Since it is a product designed as an eyeshadow, I found it inconvenient to use on wider areas of the face like the jawline.

Are there any products specifically designed for contouring that look as natural as real shadows on cool-toned skin?

Cool-toned Unpa members, please give me lots of recommendations 🙏
