You may have learned about stoma powder and stoma paste during discharge, and for the first few weeks you never needed either one. Then something changed. Maybe the skin around the stoma looks a little red, or the pouch is not lasting as long as it used to, and you are back at the drawer holding two small containers, trying to remember which one does what. You are not alone in that. Stoma powder vs. paste trips up most people, because the products look like a pair but solve very different problems. Let's explore both products to reduce any confusion you may have.
Overview: stoma powder vs. paste at a glance
Stoma powder and stoma paste solve two different problems. Powder absorbs moisture from raw or irritated skin so the barrier can stick again. Paste fills creases, folds, and gaps so the barrier can seal flat. Because they do different jobs, you may need one, both, or neither on any given change. Below, we cover Stomahesive protective powder uses, Stomahesive paste uses, the crusting technique that lets you layer them safely, a quick decision guide for caregivers, and the signs that mean it is time to call the nurse or doctor.

The short answer: powder is for skin, paste is for gaps
Here is the rule of thumb that clears up most of the confusion. If the skin is the problem, reach for powder. If the fit is the problem, reach for paste. Healthy skin with a flat, even surface usually needs neither, and adding products a routine does not need can actually cause leaks. The table below shows how the two compare.
| Feature | Stoma powder | Stoma paste |
|---|---|---|
| What it is | A fine, absorbent powder | A thick, caulk-like filler |
| Problem it solves | Moist, raw, or irritated skin that will not hold a barrier | Creases, folds, scars, or gaps that let the barrier lift |
| Where it goes | Directly on the affected skin, then brushed off | On the barrier opening or directly into the crease |
| Use on healthy skin? | No, it reduces adhesion | Yes, if the surface is uneven |
| How long to use it | Short term, until the skin heals | As long as the contour issue remains |
Stomahesive protective powder uses
Stomahesive protective powder is made from the same skin-friendly ingredients found in ConvaTec's skin barriers, so it works with the rest of the pouching system rather than against it. Its job is simple. When the skin around the stoma becomes moist, raw, or weepy, usually because output has leaked under the barrier, nothing adhesive will stick to it. The powder absorbs that moisture and forms a dry, protective layer, which gives the skin a chance to heal and gives the barrier something to grip.
Use stoma powder when you notice any of the following during a change:
- Skin that looks shiny, wet, or weepy instead of dry
- Red, raw, or peeling patches, especially where leaks have occurred
- A barrier that lifts quickly even though the surface is flat
💡Important note: Stoma powder does not belong on healthy, dry skin. On intact skin it acts like a release layer and can shorten wear time or cause a leak. It is also not a preventive product, so stop using it once the skin is no longer moist to the touch. Finally, never substitute with baby powder, cornstarch, or any cosmetic powder. Those products are not designed for peristomal skin and will interfere with the seal.
Stomahesive paste uses
Stomahesive paste works more like caulk than glue. Despite the name, it is not an adhesive. Instead, it fills the uneven spots that keep a barrier from sealing flat. For example, a skin fold beside the stoma, a surgical scar, a dip in the abdomen, or a small gap between the stoma and the barrier opening. By leveling those spots, paste helps the barrier sit evenly and keeps output from creeping underneath.
Reach for paste when the skin looks healthy but the barrier still leaks or lifts in the same place each time.
A few tips make stoma paste work better:
- Apply a thin bead around the barrier opening or directly into the crease, not across the whole barrier. Less is more.
- Let it set for 30 to 60 seconds before pressing the barrier into place so it stays where you put it.
- Expect a brief sting if the paste contains alcohol and the skin is irritated. If stinging is a problem, ask the nurse about a no-sting paste or a moldable barrier ring, which does a similar job without alcohol.
Can you use stoma powder and paste together?
Yes, and many people do, but only when both problems are present at the same time. If the skin is irritated and the surface is uneven, powder handles the skin and paste handles the fit. The key is the order, because paste will not stick to loose powder. Ostomy nurses teach a method called the crusting technique for exactly this situation. Here is how it works:
- Clean and pat dry. Use warm water and a soft cloth, then pat the skin dry. Skip soaps with lotion or oils, since they leave a film.
- Dust on the powder. Sprinkle a light layer of stoma powder over the irritated areas only, then gently brush away the excess with a dry tissue or gauze.
- Seal it with barrier film. Dab or spray a no-sting skin barrier film over the powder and let it dry. This turns the powder into a thin, tacky crust that adhesive can grip.
- Repeat as needed. For very weepy skin, repeat the powder and film steps once or twice until the surface feels dry and smooth.
- Add paste to fill any gaps. Apply a thin bead of paste to the barrier opening or into any crease, and let it set briefly.
- Apply the barrier. Center it over the stoma, press from the inside out, and hold your hands over it for a minute to help it bond.
If the routine involves only one of these problems, skip the steps you do not need. More product is not more protection.
A caregiver's quick decision guide
If you ever find yourself stumped in the middle of a pouch change, start by looking at two things: how the skin looks, and whether the barrier is sitting flat. The answer usually falls into one of four situations.
| Observation | What it means | What to use |
|---|---|---|
| Skin is red or weepy, but the surface is flat | A skin problem | Powder, sealed with barrier film. No paste. |
| Skin looks healthy, but the barrier leaks at a crease or scar | A fit problem | A thin bead of paste where the gap is. No powder. |
| Skin is irritated and the surface is uneven | Both problems at once | Crust with powder and film first, then add paste where the gaps are. |
| Skin is healthy and the barrier seals well | Nothing is wrong | Keep the routine simple, neither paste nor powder may be necessary. |
When to call the nurse or doctor
Powder and paste handle the most common skin and fit issues, but they are not a cure for everything. Part of good caregiving is knowing when a problem needs a professional eye. Call the ostomy nurse or doctor if you notice:
- Skin that is not improving after two or three changes with powder
- A rash that spreads beyond the barrier edge, has small red bumps, or itches intensely, which can signal a yeast infection that needs a different product
- Bleeding, open sores, or pain around the stoma
- Leaks you cannot trace to a specific crease or spot, which may mean the barrier size or type needs adjusting
- A stoma that changes color, size, or shape
Reaching out early is not a sign that you are doing something wrong. It usually means a small adjustment can save your loved one weeks of discomfort.
Stocking your ostomy care kit
Having the right supplies within reach makes every change easier and less stressful. For most households managing an ostomy, a well-stocked kit includes:
- Stomahesive protective powder for irritated or weepy skin
- Stomahesive paste for creases, scars, and gaps
- No-sting skin barrier film for the crusting technique and everyday skin protection
- Moldable barrier rings as an alcohol-free alternative to paste
- Adhesive remover spray or wipes, soft gauze, and a spare barrier and pouch
Because these are supplies you will reorder regularly, consider setting them up on Subscribe & Save so they arrive on schedule and you never run out mid-month. You can browse our full ostomy supplies collection for barriers, pouches, and accessories from ConvaTec, Hollister, Coloplast, and more.

Frequently asked questions
Is stoma powder the same as stoma paste?
No. Stoma powder is an absorbent powder that dries and protects irritated skin so the barrier can stick. Stoma paste is a thick filler that levels creases and gaps so the barrier can seal flat. They solve different problems and are often used for different reasons, sometimes together.
Can I use stoma powder every time I change the pouch?
Only while the skin is irritated or moist. Stoma powder is not meant for healthy, dry skin and can actually reduce how well the barrier sticks. Once the skin has healed and feels dry to the touch, stop using it.
Does Stomahesive paste sting?
It can sting briefly on irritated skin because it contains alcohol. If that is a concern, ask the nurse about a no-sting paste or a moldable barrier ring, which fills gaps without alcohol.
What is the crusting technique?
Crusting is a method for preparing weepy or raw skin before applying a barrier. You dust on stoma powder, brush off the excess, then seal it with a no-sting barrier film. The result is a thin, dry crust that protects the skin and gives the adhesive something to grip. Repeat once or twice if the skin is very moist.
Can I use baby powder instead of stoma powder?
No. Baby powder, cornstarch, and cosmetic powders are not designed for peristomal skin. They interfere with the barrier seal and can lead to more leaks and irritation. Use a product made specifically for ostomy care.
Supporting healthy skin around the stoma
Stoma powder and paste are small products that solve big problems when you use them for the right reasons. Powder for skin, paste for gaps, and the crusting technique when you need both. Beyond that, the best thing you can do is pay attention. Notice how the skin looks at each change, keep a few key supplies within reach, and call the nurse or doctor when something does not improve.
