I have pretty sensitive skin and was a little leery about trying this product for fear that it would make my skin red and dry. I have been using the product for 10 days and am very pleased with the results so far. I have only been using the serum at night and used it every other night for the first four days. The serum goes on easily and absorbs quickly. I have been using it on my face, neck, chest and the back of my right hand. I have a lot of freckles all over so I am using the serum on one hand to see if there is a noticeable difference. As of right now they look about the same. I love the way my skin feels since I have been using this product and I can really see a difference in the moisture level and the smoothness of my skin, especially on my face. If definitely feels softer and more supple. I have just started using the serum twice a day and am looking forward to even better results. The product does have subtle scent (smells like green tea to me) but the scent goes away after the serum is absorbed into the skin. I normally prefer unscented products, but I did not find this one offensive. I would definitely recommend this product.
