This powder does really well in absorbing the oil, especially for my skin (oily/combo) around the T-zone area. I used it on the last step of my makeup and didn't look oily. I do keep it around and use it when the afternoon hits just to touch up. Also, it's very convenient and you're able to put it in your bag.
I've also tried using it to control my oily hair but use it at your own risk bc it made my hair feel kind of crunchy. It did make the oil in my hair disappear but my hair consistency/feeling didn't feel to good
