A barrier ring can safely touch your stoma, and in most cases it should. The stoma is a section of intestinal lining brought to the skin’s surface, and that tissue lacks the kind of nerve endings that register sharp or burning pain from gentle contact. Placing the ring snugly against or even slightly overlapping the base of the stoma is standard practice among wound and ostomy care nurses, because a tight seal at that junction is what keeps digestive output off your skin. The concern that touching the stoma with any product will cause harm is understandable but unfounded for barrier rings specifically, and getting past that worry tends to solve a surprising number of other ostomy problems.
Why the Stoma Does Not Feel Pain from Contact
Your stoma is made of the same mucosal tissue that lines the inside of your intestines. That tissue has visceral nerve fibers, which sense deep pressure and stretching, but it does not have the somatic nerve fibers responsible for the sharp, localized pain you feel when something presses on or scrapes regular skin. You can touch, wipe, or even lightly bump a stoma without it hurting. Many new ostomates are startled the first time a nurse demonstrates this by pressing a gloved finger against the stoma surface.
This does not mean you should handle the stoma roughly. Vigorous rubbing or sharp objects can still cause mechanical trauma and bleeding, because the mucosal surface is delicate and has a rich blood supply. But a soft, moldable barrier ring resting against the stoma base is not the kind of contact that causes injury. The ring’s material, typically a hydrocolloid blend with some elasticity, is designed to conform gently to tissue contours rather than press into them.
How to Place a Barrier Ring for the Best Seal
The goal when placing a barrier ring is to fill the gap between the stoma and the opening you’ve cut in your skin barrier wafer. That gap exists because stomas come in irregular shapes, and even a well-cut wafer rarely matches perfectly. Any exposed skin between the stoma and the wafer’s edge is vulnerable to contact with stool or urine, and that is where most peristomal skin problems start.
To place the ring effectively:
- Warm it first: Roll or knead the ring between your palms for 30 to 60 seconds. Body heat makes the hydrocolloid material softer and more pliable, which helps it mold closely around the stoma base.
- Shape it to your stoma: Stretch or compress the ring to approximate the shape of your stoma’s base. Round stomas are straightforward, but many stomas are oval or irregular, especially after surgical swelling goes down.
- Press it snugly: Place the ring directly around the stoma base, pushing it gently inward so it fills any dips, creases, or folds in the surrounding skin. The inner edge of the ring can and should sit right up against the stoma, with no visible skin gap.
- Apply the wafer over it: Center and press your skin barrier wafer over the ring, making sure everything sits flat and the pouch opening aligns with the stoma.
Some people apply the ring to the back of the skin barrier wafer instead, pressing it around the pre-cut opening before attaching everything to the body. Either method works. The key is that no strip of bare skin is left exposed between the stoma and the adhesive.
What Happens When the Fit Is Too Loose
Leaving even a small gap between the stoma and the barrier creates a channel for output to reach the peristomal skin. For ileostomies, that output is liquid and contains active digestive enzymes. For urostomies, it is urine. Even colostomy output, which is more formed, can irritate skin that stays in contact with it for hours at a time. Ensuring appropriate fit and proper use of ostomy accessories helps reduce effluent leakage and prevent damage to the surrounding skin.1PubMed. Ostomy 101 for dermatologists: Managing peristomal skin diseases
The most common consequence is peristomal moisture-associated skin damage, which shows up as redness, soreness, and itching in the skin around the stoma. One review of ileostomy and colostomy patients found that roughly half experienced this type of irritation, making it the most frequently reported peristomal skin complication after general irritant contact dermatitis. Maceration, where the skin turns white, soggy, and fragile from prolonged moisture exposure, affected about one in five patients.2PubMed Central. Peristomal Skin Complications in Ileostomy and Colostomy Patients: What We Need to Know from a Public Health Perspective Both of these problems can undermine the adhesion of the skin barrier wafer itself, creating a vicious cycle where leakage causes skin damage, which causes more leakage.
A well-placed barrier ring breaks that cycle. By filling the gap and creating a secondary seal, the ring keeps output contained on the stoma side and keeps the peristomal skin dry. Clinicians have noted that using a barrier ring can improve the pouching system seal and protect the surrounding skin.3PubMed Central. Current Ostomy Care Practice Related to Peristomal Skin Issues
Flush and Retracted Stomas Present Extra Challenges
Not all stomas protrude neatly above the skin surface. Some sit almost level with the surrounding skin (flush stomas), and some actually dip below it (retracted stomas). Both of these situations make leakage more likely, because output does not fall cleanly into the pouch. Instead it tracks sideways along the skin under the wafer.
Barrier rings can help here in a way that goes beyond simple gap-filling. When you stack or mold a ring to build up the area immediately surrounding a flush or retracted stoma, you create a raised surface that mimics the effect of convexity, gently pressing on the peristomal skin so the stoma protrudes more relative to its surroundings. An international consensus meeting on convexity in ostomy care noted that barrier rings and inserts can serve as a primary source of convexity when added to a flat skin barrier, or as a supplement that enhances the depth of an already convex wafer.4PubMed Central. Use of Convexity in Ostomy Care: Results of an International Consensus Meeting
If your stoma is flush or retracted, this is one more reason the ring should sit right against the stoma base. Any space between the ring and the stoma defeats the purpose of building up that raised border. Your wound ostomy continence nurse can help you figure out whether one ring is enough or whether stacking two thin rings produces a better profile for your particular anatomy.
Barrier Rings Versus Ostomy Paste
People sometimes confuse barrier rings with ostomy paste, or wonder if the two serve the same purpose. They do overlap in function, both are used to fill irregularities and improve the seal, but they differ in key ways that affect comfort and ease of use.
Ostomy paste comes in a tube and is squeezed around the stoma or onto the wafer like caulk. It contains alcohol in many formulations, which can sting when it contacts irritated peristomal skin. It also stays somewhat rigid after application, and it can be messy and difficult to clean off during pouch changes. Barrier rings, by contrast, are alcohol-free, pre-shaped, and peel away cleanly. They mold to contours without the stinging that paste can cause on damaged skin.
For filling deep creases, scars, or skin folds near the stoma, paste may still be useful because you can deposit it precisely into a narrow gap. Many experienced ostomates use both: paste for the deepest irregularities and a ring over the top for the broad seal. But for general-purpose gap filling and stoma-to-wafer sealing, barrier rings have largely replaced paste in routine care.
How Adhesive Strength Affects Skin Health
One concern with any product that adheres to peristomal skin is the damage caused by repeated application and removal. Each time you peel off a wafer or ring, you remove a thin layer of skin cells along with it, a process sometimes called skin stripping. Over months and years of pouch changes, this cumulative trauma matters.
Research on hydrocolloid wafer adhesives has found that lower adhesive force is associated with fewer skin changes. Patients using skin barriers with adhesive force at or below about 2 Newtons showed fewer signs of skin surface disruption compared to those using barriers with higher adhesive force.5Journal of Wound, Ostomy, and Continence Nursing. Peristomal Skin Disorders in Patients With Intestinal and Urinary Ostomies: Influence of Adhesive Forces of Various Hydrocolloid Wafer Skin Barriers Barrier rings are generally formulated to be gentler than the wafer itself, since they are designed to peel away during changes rather than grip aggressively.
Ceramide-infused barriers take this a step further. Ceramides are lipids naturally present in the skin’s outer layer, and barriers that incorporate them have been shown to cause less epidermal disruption with serial application and removal compared to barriers without ceramide.6PubMed Central. Measuring epidermal effects of ostomy skin barriers If you have sensitive or already-compromised peristomal skin, this is worth discussing with your ostomy nurse. The general principle is that a product strong enough to seal but gentle enough to remove without trauma hits the sweet spot for long-term skin health.
Impact on Wear Time
One of the most practical reasons to use a barrier ring is that it can extend the time between pouch changes. A longer wear time is not just about convenience; it means fewer episodes of adhesive removal, less skin stripping, and lower supply costs over time.
An evaluation of a newer barrier ring design found that among participants who had previously used a different barrier ring, about seven in ten perceived the newer ring as lasting longer than their usual product. More than half reported that their overall pouch wear time improved as well, and the vast majority experienced no pain on removal.7Advances in Skin & Wound Care. Evaluation of a Novel Ostomy Barrier Ring with Assisted Flow for Individuals with an Ileostomy A separate study of a similar ring formulation confirmed high scores for usability and comfort, along with the potential to reduce leaks and increase how long the overall system lasted before needing replacement.8Gastrointestinal Nursing. Statistically significant improvement in peristomal skin condition due to adhesive breakdown prevention by novel barrier ring with assisted flow
That said, barrier ring use is far from universal. A survey of wound and ostomy care nurses found that a large proportion reported using barrier rings in only a small fraction of their patients.3PubMed Central. Current Ostomy Care Practice Related to Peristomal Skin Issues This does not mean rings are unnecessary; it likely reflects that many ostomates with well-protruding stomas and regular skin contours achieve an adequate seal with the wafer alone. The ring becomes most valuable when the stoma shape, body contour, or output consistency creates challenges that the wafer cannot solve on its own.
Adjusting for Stoma Size Changes
A detail that catches many new ostomates off guard is that the stoma does not stay the same size. In the weeks after surgery, swelling gradually resolves and the stoma shrinks, sometimes substantially. During this period, the size of the ring and the wafer opening need to be re-evaluated at every pouch change. A ring that fit perfectly two weeks ago may leave a visible gap today.
Even after the stoma matures and stabilizes, which typically takes two to three months, temporary size changes still happen. Physical activity, weight fluctuation, and normal bowel function can cause the stoma to swell or shift slightly throughout the day. A moldable barrier ring accommodates these fluctuations better than a rigid pre-cut system, because you can reshape it each time you apply it. Some people find that their stoma is slightly larger in the morning and smaller by evening; the ring’s flexibility handles that variation without requiring a completely new setup.
The Cost of Peristomal Skin Problems
Peristomal skin complications are not just uncomfortable; they are expensive. When the skin around the stoma breaks down, the wafer does not adhere properly, which shortens wear time and forces more frequent changes. More frequent changes mean more supplies, more accessory products to manage the irritated skin, and more visits to healthcare providers. A cost-effectiveness analysis noted that peristomal skin complications and leakage increase the cost of supplies through decreased wear time and added accessory products, and that ostomy products shown to reduce those complications offer significant financial benefit.9PubMed Central. A Cost-Effectiveness Model to Determine Ostomy-Related Costs of Care and Health Outcomes Among People With an Ostomy in Canada Using a Ceramide-Infused Skin Barrier
If you are rationing barrier rings to save money, this is worth reconsidering. The upfront cost of adding a ring to each pouch change may actually reduce your total spending if it extends wear time and prevents skin breakdown that would require additional products to manage.
Leakage, Fear, and Quality of Life
Behind every technical discussion about seal integrity and skin chemistry is a reality that ostomates live with daily: the fear of leakage. That fear is not trivial. Research consistently identifies leakage as a key driver of social withdrawal among people with ostomies. The worry about visible leakage or odor is nearly universal among ostomates who have experienced it, and it leads many to avoid social situations altogether. Over time, this avoidance can progress from anticipating embarrassment to internalized shame that affects body image, intimate relationships, and overall emotional well-being.10PubMed Central. Stoma Leakage: Prevalence, Associated Factors, and Assessment Tools—A Scoping Review
The encouraging finding is that reducing leakage can partially reverse that trajectory. Personalized appliance selection and supported care have been shown to improve self-efficacy, acceptance, and quality-of-life scores within months.10PubMed Central. Stoma Leakage: Prevalence, Associated Factors, and Assessment Tools—A Scoping Review A barrier ring is one piece of that puzzle. Knowing that your seal is secure, that you have closed the gap between stoma and wafer, and that output is not silently tracking onto your skin gives a kind of confidence that no amount of reassurance alone can provide. If you have been leaving a gap out of fear of touching the stoma, closing that gap may do more for your daily life than any other single change to your pouching routine.
When to Talk to Your Ostomy Nurse
While barrier rings are safe for stoma contact in the vast majority of cases, a few situations warrant professional guidance. If you notice your stoma is changing color (turning dusky, purple, or very pale), that is a circulation issue unrelated to barrier ring use, but it needs prompt evaluation. If you see small, raised, red bumps forming right at the stoma-skin junction, those could be granulomas, tiny areas of overgrown tissue that sometimes develop where the skin meets the stoma. Granulomas are usually treated with silver nitrate by a specialist, and while they are not caused by barrier rings, adjusting how the ring sits can sometimes reduce the friction or moisture that contributes to them.
If you have been using a barrier ring and still experience frequent leaks, the issue may not be ring placement but rather the type of convexity your body needs, the consistency of your output, or the location of skin folds and creases that require a different approach. The WOCN Society’s clinical guideline for managing adult patients with fecal or urinary ostomies emphasizes individualized pouching system selection and ongoing follow-up care to adapt to changes in stoma and body contour over time.11Journal of Wound, Ostomy and Continence Nursing. WOCN Society Clinical Guideline: Management of the Adult Patient With a Fecal or Urinary Ostomy A wound ostomy continence nurse can assess your specific setup and recommend changes that a general practitioner or surgeon may not think to suggest.
