VERY expensive but the best serum I have ever used. I am having chemotherapy and this has gone a long way to keep my skin from being destroyed. So effective--I thought the price was outrageous, but I have used La Mer products for a long time and know they work so decided to upgrade for my illness. Wow was it worth it. My assistant at work says I look years younger, and she did not even know I was using the cream. And that is with the chemotherapy! Cant wait until it is over. I bought the eye cream too and it is excellent also.
