@jtntd Torbot Skintac is an adhesive. It's been around a long time. If you try it, It's a good idea to do a patch test before you use it under your appliance, since you know you have allergies to adhesive.

You can use various different products to fill divots, including things that come in the form of pastes, and rings, strips or half circles. Sometimes people call these skin barriers, which is confusing.

Have you had a follow-up visit with a WOCN? This can be very helpful, particularly if you have allergies, as they have knowledge of various different products.

Something a lot of people have success with is Eakin's Seal. Have you heard of it or tried it?
