Thanks so much for sharing this :)  I tried a sample of the Renewal serum before but now I'm motivated to get the full size, etc. from her..  I remember her recommending layering both serums for maximum benefit.  Serums are one of the best ways to prevent accelerated aging, esp. layered underneath a broadspectrum sunscreen during the day.  I hope you'll also reveal your favorite products that you use for your lovely hair and even your natural makeup.  I love your site here!
