After a shower and gentle soap cleaning I do 2 things that has helped me. First , I use a portable hair dryer to dry the stoma area. Then after I apply the apparatus I use Hy-Tape ( very skin sensitive, and friendly, but sticks really well) . I use this as a supplement to the barrier and put a piece about 2 inches long at the top, bottom and sides of the flange. I play tennis 3-4 days/ week, I shower 3-4 times / week and live in Hawaii witth 80+ temp. My device last 6-7 days.
