The purpose of this exploratory study is to obtain preliminary data on peristomal and non-peristomal skin barrier characterisation in people living with a stoma. The main questions it aims to answer are:
* Is there a difference/similarity in skin barrier characterisation of peristomal and non-peristomal skin in people living with a stoma?
* Is there a difference/similarity in peristomal skin barrier function of different stoma types (colostomy, ileostomy and urostomy)?
* Does a stoma type/function, influence skin barrier characterisation of peristomal skin?
Participants will:
* Attend a 1-hour study appointment
* Undergo non-invasive skin procedures
