I have been using the serums for over two months. I love the smell, the feel and the way my skin looks afterwards. Use this in conjunction with the day and night cream, you also will see amazing results. I have always taken care of my skin but unfortunately used top of the line products with what else, chemicals. I am looking to age gracefully not artificially. 60% of what goes on our skin is absorbed!! There are also long term effects from all the chemicals that you will see as you age. Oh, and I do like the roller ball applicator on the eye serum. It feels so cool. Just work with it ladies it is the best way to apply in my opinion.
