Topic Explanation:
The forum topic is about seeking advice on applying Karaya powder for colostomy durability. The user has been experiencing less than usual durability with their colostomy and has been using a barrier ring on their wafer, as well as Karaya powder due to skin problems. They are seeking advice on the application of the powder, the quantity to use, and whether it matters if it gets on the stoma itself.

Advice and Insights:
- Apply the Karaya powder on the reddish ring right around the stoma. It can get on the stoma itself, but too much powder under the wafer can weaken adhesion.
- If experiencing skin problems elsewhere under the wafer, it might be yeast issues, and an anti-fungal powder might be the answer.
- Consult with a stomal therapy nurse for personalized advice and recommendations.
- Consider using Convatec powder (code 25510) sprinkled around the stoma, then dust most of it off before fitting the backplate, as it has worked well for some users.
- Experiment with different application methods for the barrier ring to find what works best for individual needs.
- If experiencing issues with the current products, consider changing the whole setup more often to avoid irritation and leaks.

Note: The off-topic reply about the packaging change and the negative feedback about a specific brand have been omitted as they do not contribute to the advice on applying Karaya powder for colostomy durability.
