Loving this stuff! It goes on light, not greasy or heavy and I can feel it tingle right away. I'm already noticing fine lines diminishing (I'm only 39 so I don't have a ton) and my skin is brighter and smoother after a week of use. A little goes a long way, I expect this bottle to last for a while. It's also supposed to help with sun damage and this year, I'm getting a lot of sun. Bonus!
