I'm so happy to come across with your product. I have used so many products that don't work for my knuckles, but immediately I started using this revive oil with the set, I began to see changes and right now my dark knuckles are fading away, I am coming in a short time to post my knuckles, thank you HNB your product is a life saver I can go out now without hiding my hands. You're the best.
