I purchased your product about 3 weeks ago after a visit to a spa where they used the vitamin c serum on face. I also purchased the AOX moisturizer from your site and I have to say that they are superior than all products I have purchased at any pharmacy or cosmetic counter. My skin feels and looks wonderful just like after a spa treatment. I am so satisfied with the results that I had to share my observation. People have commented on my skin. I have referred many friends to your products and site. Thank you.- K. Anderson
