I have rosacea myself. I poked around the internet and found lots of people with rosacea who used mineral foundation, so I decided to give it a try. Now I will NEVER use any other kind! I highly recommend your mom give it a try. The coverage is amazing, yet you don't feel (or look) like you've got makeup caked on. That's what I had to do with other foundations to get enough coverage for the redness is literally cake it on! But not with the crushed minerals. There are several brands of mineral makeup, including Bare Minerals and Jane Iredale. There are places that will custom blend colors if you need it, but most people don't (I'm told by the people who do the blending...) You can buy mineral makeup, including Bare Minerals and Jane Iredale online, but I was nervous to do that because I wanted to get the proper shade. BareMinerals offers an introductory kit with two different shades so they say you can't make a mistake chosing the wrong color. Good luck! If you have any questions about mineral makeup, ask me, and I'll tell ya what I know!
