This isn't technically a review, but you can see how NARS's new Orgasm X blush builds and blends, and how it differs from original Orgasm blush. This goes on pretty soft and sheer for how intense it looks in the pan, but it definitely layers, and using a firmer, denser brush also deposits much more color than the soft Les Merveilleuses LADUREE one I used.
(Full products listed in the Youtube description box.)
To be 100% fair, it's not a huge difference between the two once they are on, and if you own the original and love it already, you probably won't need or want Orgasm X.
I might prefer Orgasm X a little more though, since it amps up the coral-red heat of the original but is slightly lower on the chunky gold pearl which can sometimes not sit quite right on lighter skins (too yellow) and amp up texture (dryness, fine lines, pores).
This way of applying it across the inner cheek area and across the bridge of the nose was a fun way for me to try the blush while also trying an e-girl inspired look. But I probably wouldn't recommend it if you are concerned with highlighting texture around the face. If you're going to be photographed or seen only from a distance, it's great. Up close, it WILL magnify every pore. And I mean - every - pore.
If you're not a fan of that, stick with dusting this high along the cheekbones. It even works great as a softer take on blush contouring or draping, 70s/80s style, because of the reddened undertones.
