I used to have occasional seepage into a small diameter around my stoma when I was using the wafers that you have to cut with scissors to size. It caused perpetual irritation to my skin because my stoma used to change shape constantly, and the hole I had cut would sometimes be too big.
I then tried the ConvaTec Natura SUR-FIT moldable skin barrier instead. You stretch it out, and after it's around your stoma, it then shrinks back a little to ensure a snug (but not too tight) fit. What a game-changer for me. There are no jagged edges, no fussing with scissors, and the opening always fits perfectly. Nowadays, when I do a bag change, there is only a slightly more pinkish hue around the immediate stoma area, but that is caused by the Eakin Cohesive seal that I use before applying the skin barrier (flange).
I can easily go a week or more without a bag change, even with frequent showering. Everything dries quickly, and the adhesives don't bother my skin. The only thing that ever irritated my skin was the output from leakage, which was resolved.
As individuals, we all have different needs for our stoma care, and I hope you can find your perfect solution. Yes, it can be as confusing as heck in the beginning, but there is no problem that can't be solved... eventually. Let your body be your guide—it will tell you what it likes and doesn't like. For example, my husband's skin is uber sensitive to every chemical, so if he had a stoma, he might be bothered by the actual adhesives themselves.
