You're getting some good advice, which is what this forum is so good at. Bottom line is if you have skin irritation caused by a your skin coming into contact with your output.......it's no biggie. Just put some stoma powder on it when you change your barrier to keep it dry and your skin will heal itself. One time irritations are easy for you body to overcome. But if you continue to experience leakage and your skin continues to get exposed to your output..........that's a whole new ballgame.
Something to note is that a properly applied (and functioning) barrier should work the same whether your output is solid or liquid. It should keep your output off your skin and not leak. People with urostomies are basically peeing into their bag, and they keep their urine from contacting their skin via their barriers. So if you get seepage with a more liquid output..........you may have an issue with how you're applying your barrier. Not an issue I'm guessing with your more solid output........so no need to change anything.......but something to note for the future if you need to be on meds longer or your diet causes a more liquid output.
