What really amazed me is when I forgot to put powder on one day and I could't tell if I had or not. It turns out that I did forget to put powder on that day but I didn't feel the need to apply it once I realized I had forgotten it. My face stayed pretty much shine free for most of the day and the foundation didn't go anywhere. I can honestly say that I would feel completely comfortable not even using powder with this foundation.
Like I have previously mentioned, this foundation keeps me mostly or completely matte throughout the day. This is the best product I've come across for controlling oil on my face. You do have to be careful because it can cling to dry patches and can look cakey if you aren't careful. I apply this foundation with my beauty blender and I don't ever have a problem with it looking too heavy on my skin.
I know this foundation is $36 but I think it's totally worth it. I highly recommend this foundation to anyone that tends to get oily skin throughout the day. I wouldn't recommend this to normal or drier skin types because it can look heavy and cling to dry patches. If you are thinking about picking it up, please do.
