Review (4/5): it does work
This stuff actually works. It's 30% dmso, and I think that the recommended strength of 70% probably works even better. I started out with tiny amounts on my knuckles, in case I had a skin reaction, which I did not. In fact, this product made my skin nice and soft. The rose scent is nice and strong enough to cover up any other icky smell that the dmso might have. I had to smear a lot more on my knees before I could taste anything. It's kind of metallic tasting.
I think this is a good dmso starter product, if you want to try it but are a little nervous about it. The 30% strength takes the edge off the pain in my knuckles, and when this is gone, I'm going to try something a little stronger.
