I have super oily skin, not just around my T zone but my whole face. I am on my 4th repurchase of this product and it is phenomenal.
Setting my makeup with this powder allows it to say on longer than it would when using other powders.

To combat a bit of a white cast I just lightly go over my face with a powder of my skin tone and ta-da long lasting make up!

I use this in conjuction with the All Abut Matt setting spay.
