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
