After spending a week in Hawaii all of my "liver spots", which I had carefully bleached off all year, returned with a vengence. I went to a day spa to get a pedicure during a 3-day break in California on the way back from Hawaii to my home in Maryland. My face was driving me so crazy that I asked them what they would recommend for these brown spots. They recommended several products in a line called Christina. They have a high concentration of Vitamin C. Then then told me that, if this did not work, I would be looking at Obagi (big bucks). Well after 30 days on the Christina Day Serum and Night Serum, I can't believe the difference. Almost no liver spots! The down side. It's hard to find the products. The day spa is called La Bella and they have a web site from which you can order. I could not find another way to get them. Just thought I would pass this along as I have tried many things that did not work and were expensive and this line was cheaper than Obagi and you do not have to use like 12 products.
