Foundation - Help!

[lyssymac]

Help! Suggestions!! 
I am having major separation with my foundations lately and need some suggestions of others to try. I’m very oily in my t-zone! 
I use the milk grip primer and a setting spray. 

Current foundations: milk stick foundation, Bobby Brown stick foundation

I've been using the Smashbox 24-hour hydration foundation for years and I love it. It's not meant for oily skin specifically, but it's a good quality foundation that won't separate after long wear - I've gone up to 11 hours. Even though I'm oily, I don't like mattifying foundations because I hate the dull finish. To combat the oiliness, I use an oil-control primer and setting spray. The combo of hydrating foundation over mattifying primer and setting spray leaves me not too matte to the point of looking dull.

I use the Urban Decay De-Slick Oil-Control Makeup Setting Spray 4 oz/ 118 mL and an old tube of the Urban Decay De-Slick Primer
