I've been using this colorless and odorless powder on myself and my clients for years. This powder is a staple in most professional makeup artists' kits.
I use this to lightly set my under eyes and other places where I concealed or highlighted. You can also bake or cook your makeup with this powder, too. There is no flashback in pictures, so it's perfect for photography and it doesn't add any color like most other powders do.
Added benefit it's pretty inexpensive!
I get my powder at www.naimies.com/ in LA or you can get it here:
