I have extremely oily skin, like foundation does not stay on at work. I noticed a huge difference when using this. It didn't make me dry, but helped get the natural oils to an acceptable level. I totally recommend it.
I have combination skin, but it gets oily very often! For me, it leaves my skin a little dry so I follow up with a moisturizer. My mom has oily skin and she uses the 'Mask of Magnaminty' which is also available at LUSH.
