Peristomal Skin Care: Guide to Preventing and Managing Irritation

Published: October 19, 2026Updated: October 19, 2026

Proper peristomal skin care protects the delicate skin around an ostomy from digestive enzymes, chemical irritation, and mechanical trauma. Following a disciplined maintenance routine ensures a reliable appliance seal, prevents painful skin breakdown, and promotes long-term stoma health. This guide outlines step-by-step techniques to maintain skin integrity, apply protective barriers, and resolve common complications.

Quick Summary

Prevent stoma skin irritation by gently removing adhesives, cleaning only with plain warm water, maintaining a precise barrier cut, and allowing skin to dry fully before application.

Step-by-Step Guide

1

Gently Remove the Used Appliance

Begin by supporting the surrounding skin with one hand while gently peeling the adhesive barrier downward with the other hand. Use a silicone-based, sting-free adhesive remover spray or wipe to release the bond gradually rather than pulling forcefully. Rushing this process strips the epidermis, causing mechanical trauma and painful skin irritation.

Important: Never pull or rip an ostomy wafer off quickly, as this peels away the epidermal layer and leaves skin vulnerable to infection.

2

Cleanse the Peristomal Skin with Water

Wipe the skin around the stoma using warm water and a soft washcloth or disposable dry wipe. Avoid soaps that contain oils, moisturizers, fragrances, or deodorants, as these leave residues that prevent the next wafer from adhering. If soap is necessary to remove stubborn residue, use a mild, residue-free cleanser and rinse thoroughly.

Important: Do not clean the area with alcohol, hydrogen peroxide, or harsh antiseptic solutions, which dry out and chemically burn peristomal tissue.

3

Inspect and Completely Dry the Skin

Carefully examine the peristomal area under good lighting for signs of redness, rash, or skin breaks before applying fresh equipment. Pat the skin completely dry with a clean towel or dry gauze, or allow it to air-dry for a minute. Hydrocolloid adhesives require a dry surface to bond, and trapped moisture increases the risk of fungal overgrowth.

4

Accurately Measure the Stoma Base

Measure the stoma diameter at its widest point using a stoma measuring guide card, especially during the first two months post-surgery when stoma size changes rapidly. Trace and cut the barrier opening so it fits snugly around the base of the stoma, leaving only a 1/16 to 1/8 inch (1.5 to 3 mm) clearance. If the opening is cut too large, stool or urine will contact and chemically erode the exposed skin.

Important: An oversized wafer opening is the single most common cause of peristomal moisture-associated skin damage (MASD).

5

Apply Skin Barrier Products for Protection

If the peristomal skin is weeping or denuded, use the 'crusting' technique by dusting a thin layer of stoma powder over the area and sealing it with a no-sting barrier spray or wipe. If you have skin folds, creases, or an irregular surface around your stoma, apply a moldable barrier ring or stoma paste to fill in defects and create a flat, leak-resistant seal.

6

Mount and Seal the New Barrier

Position the pre-cut skin barrier directly over the stoma, pressing firmly around the base and working outward toward the edges to smooth out air pockets or wrinkles. Place your warm hand over the applied wafer for 30 to 60 seconds; body heat activates the hydrocolloid adhesive, significantly improving adhesion and security. Once secured, attach or close the pouch securely.

Frequently Asked Questions

How often should I change my ostomy pouching system to protect my skin?
Most pouching systems should be changed every 3 to 5 days on a planned schedule. Change it immediately if you feel itching, burning, or suspect that effluent is leaking beneath the barrier.
What does it mean if the skin under the wafer is bright red, itchy, and dotted with pimples?
This commonly indicates a fungal yeast infection (candidiasis), typically triggered by moisture trapped under the barrier. Consult your ostomy nurse or doctor for a prescribed antifungal powder; regular antifungal creams should not be used as they stop the wafer from sticking.
Can I use baby wipes or regular moisturizing wipes to clean my stoma?
No. Most commercial baby wipes and pre-moistened cleansing wipes contain lanolin, oils, or conditioning agents that leave an invisible film on the skin. This film prevents the adhesive barrier from sticking properly, leading to premature leaks and skin irritation.
How do I heal skin that is already raw and weeping fluid?
Clean the area with plain water and pat dry. Apply a light layer of stoma powder specifically to the raw, moist areas, gently dust away any excess powder, and seal it with a sting-free barrier film (the 'crusting' technique) before attaching a new wafer.
