HI, I came across this extensive blog on Best Products for Oily Skin - Long Lasting Foundation, Primer, Powder & Eye Makeup . I think you would really find it helpful - check it out!

Here's another article on 12 Best Products for Oily Skin.

thank you :) ill read up on it right now !

One of the best I have found is Bare Minerals.  It is made from all natural minerals (no additives) and does not add oil to your face.  Be sure to get the "Original."  It is a powder you apply with a brush, and it is a great foundation with good coverage. 

Also Pur Minerals is good.  It, too, is made from natural minerals (no additives) and is a baked fomula; so it is not a powder.  It is comparable to Bare Minerals, just not a loose powder.

I recently bought the new smashbox 15 hour studio skin foundation and it really controls my oil throughout the day! It dries to a matte finish and rather quickly. I have really big pores in my t-zone too. I only have to blot about once a day. Before I bought the smashbox foundation, I was using ysl teint resist which is still one of my favorites but it does make me oily faster and have to blot 3/4 times a day. If you do decide to buy the smashbox foundation, it is better for people with yellow undertone because the foundation is quite yellow. I apply it with my beauty blender.

Have had terribly oily skin for years, and awful acne. Heard that primer was the solution--couldn't find one that worked (tried at least half a dozen). Tried several toners and other stuff, none worked. MAC ProLongwear foundation and Blot powder have really helped my skin look less oily throughout the day! I highly recommend.
