I feel like glowy is diffused light as opposed to looking oily. Mainly on the cheeks, nose, clavicle, etc. Higher blur but not in an uncanny way.
There seem to be more and more multi products coming out. I know there is a pen style one that has eyeliner, eyebrow liner (basically the same lol) and mascara I think. I would imagine that and some cream products for eyes, lips, and cheeks would make things super easy!
1000%. I am seeing it pop up more and more on my feeds.
