I have been changing my dad's ileostomy since 2017. Recently I tried something different that helps very well. So i put the powder around my dad's stoma, before I put the ileostomy bag on my dad's stoma, I put vaseline or aquaphor around the ring of the ileostomy bag wafer. After that I put the ileostomy bag on top of the stoma and voila!!! Its extra protection!!! And it helps my dad's stoma not get as many wounds as it did before.
Vaseline is magical! Hope this can help the ostomates out there if you need extra protection.
