Just my experience
I was hopeful when l was looking for a non evasive treatment for Dupuytrens Contracture. A cream to help with the skin cords that form on the hands. As a musician l use my ring and pinky finger a lot. Based on the dozens of five star reviews l gave it a try. I was surprised to not find any reviews on Trust Pilot. That alone is kind of a red flag. After 2 months, twice daily l really had minimal results. Still had pain opening and closing my hand especially in the morning. Mobility in my fingers did not improve. First time l bought it living in Canada and with the exchange cost around $70. The next one l got a discount. Would have been worth it with results but sorry to say l didn't experience any of them. I started using a hand moisturizer with vitamins and it's about the same result. Softer hands but not much actual improvement. Nobody wanted it to work more than l.
