There's one Dr. Murad product I really love, and only use under foundation on days when I really want to minimize the wrinkles (I am 58). It's this wonderful Essential-C cream, and it feels like silk when you put it on--and it really does give my skin a lovely and youthful boost. BUT, it's 80 dollars. It lasts, though, for about 3 months (used about 3-4 times per week). It's really wonderful, and I agree with the other respondent about Perricone products--nothing!!
