Laura Mercier Minerl Foundation Powder - Rave Review

Laura Mercier Mineral Powder SPF 15 Classic Beige

This review comes with a story that may have to have a part 2.  When my mom was visiting she ran out of her powder and I ran out of my mascara, so we went to Sephora.  I told her she has to try this Laura Mercier Mineral Foundation.  I have read so many excellent reviews on it, especially for women with mature skin.  We found the perfect shade and she was sold.
Now I am giving this mineral foundation RAVE reviews because since my mom has been wearing this, she has been complimented over and over on how young she's been looking, how beautiful her makeup is, and women asking her what she uses on her face.  She says it looks like she got a mini face lift when she puts it on.  Now a mini-face lift, that is a rave review from her.  
My mom is in her 50's.  This foundation last all day for her, which is great because they are in the restaurant business,  long hours, stress, and heat and it looks perfect.  Her pores are minimized and it doesn't settle in any lines, it smooths them out.
So, this is why there has to be a part 2.  I have to try it out next to tell you what it looks like on someone in there 30's, maybe it will make me look younger too.
Have you tried this foundation?  What is your favorite mineral foundation?
