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.
After some time using the gel I found the product was a gem. I really, really am a happy camper!! I am very pleased with the product and I have noticed favorable results after such a short time using the gel on obvious parts of my body.
