I have loved using this N°7 Advanced Retinol 1.5% Complex Night Concentrate. In just a little over a week, I'm already starting to see some results, but nothing dramatic. My skin has been feeling softer and it appears a little smoother, and looks healthier. It's easy to use, is gentle, and doesn't irritate my skin at all. It absorbs quickly, isn't greasy, it's very lightweight, and only takes two small pumps of cream for each use. I definitely recommend giving it a try.
