I had endoscopic surgery that left me with four, dime-sized scars across my stomach. I researched which scar treatment would work best and these scar strips were recommended. I put the scar strips on as soon as my scabs were gone and it seems to be working well. It has been a little over a month, but my scars are soft and smooth. One of the scars was originally puckered from the stitches and now it is smooth and level as the rest of my skin. The scars are still bright pink but the box recommends wearing the strips for six to eight weeks so I still have a little time to go.
