Products that are multi-use blush/contour/eyeshadow? Is it a trend or actually a good technique

Downloaded Xiaohongshu for makeup tips and noticed that a lot of creators doing "clean makeup" tutorials using the same product as an all over face product (contour, blush, eyeshadow). I love the look it achieves, and it seems to my alley as a makeup minimalist.

The one I see recommended most is this duo blush/highlighter palette from Red Chamber but I'm unfamiliar w the brand and the videos seem to be sponsored so just wanted to crowd source some thoughts about this technique and any products you like for this application style. Image attached!
