This serum is wonderful, I immediately felt the tightening effect on my face. It looked like my fine lines and wrinkles were vanishing before my eyes. And that was only the first application. After using this serum on my face for 2 months I look younger and my face is more hydrated than every before. I will continue using this bottle and buy more. I love the way it smells and deserves more than 5 stars. I would like to disclose that I received this item at discount in exchange for my honest and unbiased review.
