My son began using DrySee® bandages 24 hours after he had surgery earlier this year. His favorite part about the bandage was that once it was on there, he never had to worry about it because it did its job. The last bandage he used, we left it on for three days, and in that three day period, he swam twice and took two showers and it never leaked. Of course if it did get wet, I would’ve known to change it! I knew it had not leaked because the outer line on the bandage was not dark- and when I took it off, it was as dry as can be apart from where the antibacterial ointment was. From a medical standpoint, I know that wounds can become infected very easily if they are wet. Because of that, the bandage provided me with a peace of mind knowing if I needed to switch the bandage out.
