I found Hy-Tape while searching for something to protect a scar I have while on a three week tropical vaction. I had surgery and was told I needed to keep my scar out of the sun for one year or it would get very dark purple. My scar is 13 inches, from sternum to pubic bone, so it was either find a way to protect it or no bikinis for me....Hy-Tape solved my problem! For three weeks in the beautiful South Pacific, every morning I carefully applied the tape to the length of my scar and it was 100% protected. It stayed on in water and the hot humid weather and didn't cause any irritation even with three weeks of use everyday. (I should add that my scar was 6 months old at the time). This tape is awesome! I highly recommend it for sensitive skin.
