I've been using the regular Smashbox Photo Finish Primer for about 10 years and it's the best primer I've ever found. When I saw that this one was also supposed to fix dark spots I was really excited! As a primer it worked pretty well although not as good as the regular primer. As for the dark spots I guess I haven't been using it long enough to see a change. I think once I finish this one I will probably just save a few bucks and stick with the original though because as a primer it just works better.
