If I get irritated here and there underneath my appliance, from repeat leaking, I’ve used a dusting of stomahesive powder, blow off any excess, then dab with non sting skin prep…for more diffuse areas I’ve used the ultra thin duoderm, that someone suggested on the skin around the stoma, then put the appliance on. If I have an itchy rash, like from moisture, I treat it like a fungal issue, and dust on some Desitin powder, blow off excess and dab it with skin prep before putting on the appliance

Your main goal is finding a pouching system that works better and doesn’t leak. Is your stoma high enough above the skin or closer to skin level? If it’s closer to skin level, barrier rings and a convex flange may help. I have an ileostomy with more liquid stool. I use Brava barrier rings and they are awesome. I also try and eat more binding foods to firm things up a bit, but when all else fails I do use Imodium.
