What is Convexity?
Convexity is the outward curving of the baseplate or skin barrier.1,2 The wafer curves outwards towards the skin.3 Different convexities manage the irregularities of a stoma.4 and apply a uniform pressure to the immediate peristomal skin, improving the projection of the stoma for drainage.5
Convexity also helps maintain a secure seal between the pouch and the skin, therefore simplifying stoma management for patients and enhancing their quality of life.6
