PLS HELP !!!! Why does my Bare Minerals Matte foundation and MAC studio finish not last throughout the day ?

I have to reapply them throughout the day...also my face is oily


How do I make them last throughout the day ???


I put the MAC studio finish concealer under neath my eyes to help conceal dark circles...the inner corner of my eye is oily too.





If you didn't already know Bare Minerals Matte is a powder foundation....and it's suppose to hide oily skin...but mines doesn't last a long time...i don't know what i am doing wrong.PLS HELP !!!! Why does my Bare Minerals Matte foundation and MAC studio finish not last throughout the day ?
Do you wear primer?





Primer is a must to keep any makeup on your face and to keep from running off.





It also helps with evening out your makeup better. (:





Go to sephora and tell them your skin type and what kind of primer they recommend.PLS HELP !!!! Why does my Bare Minerals Matte foundation and MAC studio finish not last throughout the day ?
