This topic is all about finding the right skin-protectant film or layer to use under an ostomy barrier. The person who started the discussion is dealing with some skin irritation around their stoma due to leaks and is looking for advice on what products might help. They have some older supplies but want to hear about more current options that others have found effective. Here are some insights and advice shared by others:

1. The person already has 3M Nexcare Absolute Waterproof tape and learned it can be used under the wafer without affecting how well it sticks.

2. Dansac Tre Seal is mentioned for its extra-wide edge and off-centered hole, providing added protection, especially at the bottom of the stoma. However, older supplies might lose adhesive strength over time.

3. 3M Cavilon No-Sting Barrier Film, available as wipes or spray, is praised for its effectiveness, especially when used with a light dusting of stoma powder. Many users have had long-term success with it.

4. Duoderm by ConvaTec is noted as effective, though some find it a bit expensive.

5. 3M Nexcare Absolute Waterproof Tape is a budget-friendly option that can be placed over irritated skin and still allows the wafer to adhere while the skin heals.

6. Brava Skin Barrier Wipe, which is silicone-based, is recommended for those with allergies to adhesives or hydrocolloids. It helps improve wafer adherence and is gentle on sensitive skin.

7. Silicone is becoming a popular material in ostomy care, with adhesive sprays and brush-on liquid glues available for those who can use them.

8. Convatec 2-inch Barrier Ring is useful for preventing leaks around a flush stoma, typically lasting about two days before it starts to break down.

9. A general tip is that even older products might be worth trying at home, as everyone's skin reacts differently. Testing can help find what works best for you.
