I began using the Anti-Age Regimen on my face and neck in February 2011 and added the Anti-Age Renewing Serum shortly thereafter. I found that my neck needed more time to adjust to the active ingredients, so I started a little slower on that area and used as tolerated. After four weeks, I started seeing results! After six weeks, I had a "WOW" moment. I couldn't believe the changes in my skin. I immediately took pictures to share my results. I am so excited!
