I love this serum. It absorbs quickly and does not leave my skin feeling greasy or oily. I still use my moisturizer with this. A little bit does go a long way. I use a few drops and I am good to go. This seems like it will last a long time because honestly, it doesn't take much. My skin feels hydrated and refreshed. My skin overall looks brighter and more even. I received this product in exchange for my honest and unbiased review. My opinions and experiences are completely my own.
