It works.
It is the first time I used it on a minor burn. I put it in almost right away. The burn hurt quite a bit for a couple of hours, then dwindled to minor pain until a few hours later it didn't hurt at all unless it got bumped. Even that evening when I took a shower the little bit of warm water that got on it it barely hurt. So far I'm very pleased and I guess more times will tell if the story is the same. The picture shows what it looked like by evening.
