I think this is the best hyaluronic serum. I've been using it for over 10 years and it works wonderfully on my sensitive skin. I've been tempted to switch to Dr. Barbara Sturm to just try it out, but the price difference is huge and I love the minimum ingredients in the Cellex-C product. So I've decided to stick with what I know works for a reasonable price.
