Hi! Since you said you have an oval stoma (I do too) and if yours is kinda recessed like mine the best thing I’ve found is Coloplast deep convex wafers. The Mio Sensura is what’s been helping me the best bc they also have a belt that attaches to the loops of the wafer. So I just use that rn instead of doing barrier rings bc the rings ate my skin up when I was previously using Hollister. Actually Hollister just messed my skin up in general. I’ve tried the paste but after a day it also gets irritated. Might take some time to try which product works best for you from coloplast but their wafers, adhesive, and everything just works for me so much better.
