Silken™ Silicone Stoma Gel - Trio Ostomy Care

Is the skin surrounding your stoma uneven causing regular leaks?
Does your stoma paste leave gooey residue on your skin or hurt your skin on removal?

Sound familiar? That’s why we’ve found an alternative to traditional hydrocolloid stoma paste that is kinder to skin and we want everyone to know about it.

Trio Silken silicone gel is made with Sil2™ Breathable Silicone Technology. Sil2™ supports the skin’s natural barrier function and allows the skin around your stoma to breathe and heal by protecting it from irritants.

Only a small amount of Silken is needed, apply it straight from the tube to the affected area around your stoma where the leaks occur. There’s no need to spread the gel or wait until it’s dry, simply apply your pouch in the normal way, placing it directly onto the moist gel. Silken will solidify slowly, remaining soft until the creases and gaps in your skin have been filled through normal body movement.

How is Trio Silken® Silicone Gel different to stoma paste?

Silken, although fulfilling a similar function to stoma paste, is a very different product. Its silicone formula gives it the flexibility to fill skin folds and create an even surface for your ostomy bag or base plate. Trio Silken® solidifies over time using the skin’s natural moisture to set, helping it to fill gaps and creases as you move around. It does not absorb body waste or output making it more hygienic than paste. It also removes in one piece without leaving sticky residue.

What’s the difference between hydrocolloid and silicone?

Hydrocolloid is an absorbent material used in many ostomy products, it’s designed to absorb moisture and the more it absorbs the better it sticks. When used in ostomy, output and sweat can be absorbed by the hydrocolloid products and held against the skin, causing irritation and sore skin as well as causing the hydrocolloid to break down and lose integrity. Silicone maintains a good adhesion with skin but does not absorb waste making it kinder on skin and more hygienic. It’s hypoallergenic, so less likely to cause irritation, and the silicone in Trio products is also responsive, fitting and moving with your stoma and body to improve the fit.

How do I get Trio® products on prescription?

You can speak directly to your delivery service and ask them to switch your product, however some prefer for you to speak to a healthcare professional before changing products. In this case, speak to your stoma care nurse or GP to get your prescription updated.

How will Genii™ ostomy seals adhere to the skin if they are not absorbent?

Absorbency is a requirement of hydrocolloid to enable it to achieve adhesion, however silicone products are designed to adhere to the skin without the need to absorb liquid or body waste. This results in instant adhesion and keeps corrosive output and body fluids away from the skin providing a cleaner, more hygienic solution.

Can I shower whilst wearing Genii™ ostomy seals and Genii™ flange extenders?

Yes. Genii™ ostomy seals and flange extenders are non-absorbent and adhere well to the skin allowing the user to shower without fear of the water affecting adhesion.

Can I use Trio® silicone products on wet skin?

Most ostomy products will struggle to adhere to very wet skin. If your skin is very sore and wet, you should seek medical attention and take advice from your healthcare professional. However, if your skin is mild to moderately wet, you should prepare your skin as normal prior to any appliance or bag change, then apply the Trio product as normal. This includes washing and drying the skin and applying powder if necessary.

How long can I leave the Trio® silicone products on for?

Trio® silicone products are designed to remain on the skin, delivering their full benefits, until you are ready to change your appliance/bag. Trio’s custom formulated silicones do not break down in the presence of body fluids and are designed to remain on the skin for prolonged periods of time.

What happens if I appear to get skin irritation after I use Trio® silicone products?

It is important to note that silicone is chemically inert and unlikely to cause skin irritation. Silicone is used widely in all areas of healthcare for this exact reason. However, if you feel that irritation has occurred, remove the product in question from your skin and clean the skin thoroughly with clean, warm water only. If the irritation persists, then discontinue use and seek advice from either the Trio Customer Service helpline or your Stoma Care nurse. You may wish to patch test the product before use, by placing it on another area of the body to see if skin irritation occurs away from the stoma site.

I have granulomas, can I use Trio Silken® Silicone Gel?

Yes. Trio Silken cures into a soft, silicone, adhesive, protective gel that can help to reduce the friction that often causes granulomas.

I have a fistula, can I use Trio Silken® Silicone Gel?

Yes. Trio Silken® silicone gel is safe and effective around fistulae. You may want to discuss your fistula with your healthcare professional before changing products.

How does the price compare to my current product - does it cost more?

Trio® silicone products have been priced in line with traditional hydrocolloid products to enable our advanced technologies to be delivered at an affordable price for ostomates and healthcare providers around the world. For individual product pricing, you can speak to our Customer Service team or your local distributor.

Do Trio® products contain alcohol or latex?

No. None of the Trio® silicone product range contains any alcohol or latex.
