I wasn't sure where i should post this but yeah... any who

i recently bought udpp and not even 2 hours in it's started creasing! so that was a bust... but my question is am i putting it wrong?

EVERYONE has their own way of putting on their make up so here's mine...
AND NOTE: that if i am putting the primer on wrong please tell me cuz it looks disgusting! lol

1st: moisturize
2nd: studio tech on my eyes (as for concealer) and other red spots on my face *190
3rd: mineralized satin finish foundation (all over, except for eyes) *187
4th: urban decay primer potion (on eyes)*194
5th: select sheer pressed powder (all over except for eyes)*129

for 6th and 7th depending on what look i want for my eyes and blush

do i put the udpp before any foundation ? im sooo confused please help me!
