I fell for the hype OP. It's very heavy and that just isn't something I enjoy so I do regret buying it as I can't bear the greasy rich feeling on my skin- even at night. Also quite a few things in it I'm not a fan of such as silicone, shea butter, essential oils (they break me out).
It's true that it leaves a glow but to be honest I can't see that it's anything you couldn't achieve by using something like the Becca backlight filter or mixing some strobe cream in to your usual moisturiser, anything very rich will give some sort of glow.

Not a fan of caroline hirons but she covers it quite well in the above, I think, and i agree with her on this.
