i've tried her drying potion, complexion corrector, and aerosole mist -
products were ok, but the price kept me from reordering. the complexion corrector was the most expensive at $75, but it worked, i just couldn't use it long term because it changed the texture of my skin in the spot i was using it.
i've used perricone as well and i didn't get the results i expected. for me murad products worked much better. the things that worked for me from perricone was the advice on omega3s. i eat salmon a couple of times a week and a handful of walnuts or almonds daily. along with my normal regime, my skin stays looking pretty good.
