I adore this vitamin C serum. It goes on like silk and absorbs quickly. My skin has a nice bright glow after I use it, and i feel confident that it is protecting my skin and providing the best nourishment from any vitamin C serum available. Since my skin tends toward oily, the 20% works best for me

I have been using Obagi Vit. C serum for 26 years. I have tried other Vit. C serums and NOTHING compares. You will immediately see the brightness once applied to the skin. A little goes a long way. I use 1 drop on my forehead, 2 drops each cheek and 1 drop on the chin press into the skin.
