I've just started using mederma, Yesterday 1st day went well applied it right after my shower. But today 2nd day as soon as I applied it. It started itching like crazy. I couldn't stand it so I actually rinsed the area with warm water. It's upsetting I spent all that money on something I'm not able to use. The itching is unbearable.  My scar is very fresh due to surgery I don't know if that plays a role. However I have reapplied the gel and rubbed it in for a minute or so seems like this time thw itching is a whole lot less.
