Long periods underwater or exposure to running water can make the scabs or softened new skin fall off. This prolongs the healing process. Immersion in cold water for more than a minute or two slows down blood flow, which in turn slows down scar healing.
Recently I was unfortunate to have an accident in China. After surgery it looked as though someone had stitched my wound as they would a flour-sack. Following the directions I applied Scarfade and after the first month noticed dramatically reduced redness and the scar was beginning to smooth. After the 2ndmonth 80% of the scar was as smooth as the surrounding tissue and kept improving while using the product. What’s also remarkable about the product is how little needs to be applied to the area and how long it lasts.
