Im in love with this product. I have very sensitive skin and a lot of freckels and sun spots. In 3 days I noticed my skin more bright and uniform. It also makes my skin feeling moisturized (just a light sensation) and Soft. Unlikely other seruns I had used, it doesn't smell bad as iron and doesn't make my skin sensitive: actually it improve my skin barrier. But it feels a little stick, so I rather use this serum on evening. I totally recommend
