Mature creepy eyelids?! I am offended! 
This is actually pretty tempting. The Urban Decay eyeshadow primers appear to be more or less “the standard” (or maybe they just send out a ton of PR samples to YouTubers), get that and the Laura Mercier translucent powder and you’re halfway to being a beauty guru 
I’ve only used the Milani eyeshadow primer myself… (plus things that aren’t sold as eyeshadow primer, like my concealer, a normal full face putty primer, and the ColourPop white gel eyeliner pencil - definitely my fav out of those 3, wear purple eyeshadow without looking like you lost a fight!)
