Well, Clinique has entered the mineral makeup fray with their Superbalanced Makeup, which has identical packaging to my Smashbox fave. And it's $34.50 for 18g, versus the Smashbox, which is $59 for 21g, so it's quite a bit cheaper. My friend Shelly, a girl who knows her makeup and a fellow mineral makeup devotee (she got me into bare minerals to begin with), tried this and really likes it.
Here's the thing: the Smashbox version has all sorts of vitamins and antioxidants in it, and supposedly reduces the appearance of wrinkles. And I feel like it really works! My skin responds really well to it. And I feel like my skin really glows after I use it. So I'm not sure if the Clinique version will do the same thing or not. But at that much of a price difference, I think I'm going to try it once I run out of Smashbox. If anyone has used the Clinique version, or if you've used both Clinique and Smashbox, let me know what you think!
