I do not frequently use a curling iron, rare actually, so lesson learned to wear sleeves when using one. My lack of experience resulted in a burn on my shoulder. It blistered, and I did not take note to care for it properly until I felt it be popped/opened later that morning. I knew I was in trouble for a scar since the blister opened. I had experienced a popped burn blister years ago and used Mederma, but that did nothing for it. I researched, found Scar Smart, and took a chance. I tried their Scar Smart sheets too, but I found their gel more practical for where the popped blister was located since I carry bags on my shoulders daily and that was not conducive for the sheets. I waited till the popped burn blister was dry, then I followed the directions every day from May 4th (the first picture) until beginning of August. I also kept the scar covered or under sunscreen when I was outside. I am so happy with the results! I reduced to using the gel once a day, every other day, in August, but I'm going to start back up 2 times a day to see if it can go lighter even more. I highly, highly recommend this product. And to wear sleeves when using a curling iron!
