Personally I have never cared for their moisturizer as I have dry skin and it just didn't do the job, but I used to love their foundation (back in the days when I wore foundation!). It's weird, the older I get the less makeup I actually use and the better I think I look. If you have dry skin, I would encourage you to look into the cream vs. powder options (i.e., blush, eye shadow). These have made a huge difference for me. Although I do have to say, mineral makeup isn't drying the way some other powdered make-up is.
Good luck! Going to the make-up counter is so fun, especially when the person is really knowledgeable. I also think every woman deserves to treat herself to something really fabulous.
