This is a great product that WORKS and is a terrific value - as are most BC products. It contains active Vitamin C - so it you are sensitive use caution.
This is a great facial serum containing 20% vitamin C. The packaging is a small, white glass vial with a eye dropper dispenser. I use this night and day before my moisturizer. It seems to help my skin hold in moisture as well as smooth out fine lines and wrinkles. I was using 5-6 drops for each application but have since upped it to about 10 which I think is the perfect amount. This serum has also helped improve the clarity of my skin which I think is a big bonus. The ONLY thing that I think is negative about this is the smell if you don't get it off your hands before going to bed. If I don't wash my hands after using this, my hand smells like I put it in a bag of cat food in the morning. I chalk that up to the amount of vitamin C in the product and the fact that it's oxidizing overnight on my hand when I don't get it washed off.
