I like Guerlain, but it's pricey. For a cheaper option, I like L'Oreal True Match and Maybelline Dream Matte powders. Another good one is Jane Iredale.
Ok thanks. I will look around and make a discussion.
I always felt like powder and foundation aged me...I'm lucky enough to get away with the "freshly scrubbed" look. I try to fix my skin from the inside: poached salmon and blueberries almost every day seems to help a lot!
