This topic is about a user experiencing issues with Coloplast Brava Elastic Barrier Strips, specifically that they are not sticking to the skin as they used to. The flange or wafer, however, is still adhering well. The user is seeking advice on why this might be happening and how to fix it.

Here are some helpful insights and advice:

1. **Check for Defective or Expired Batches**: Adhesive performance can decline if the product is past its expiration date or has been stored improperly. It's worth checking the expiration date and considering if the current batch might be defective.

2. **Verify Skin Preparation**: Ensure that the skin is properly prepared before applying the strips. Any moisture, oil, or lack of dryness can prevent the strips from sticking, even if the wafer adheres well.

3. **Contact the Manufacturer**: If only the current box of strips is problematic, it might be a good idea to contact Coloplast. They can help determine if it's a defective lot and may offer replacement strips.
