Does filler always create permanent production because of collagen production?

The concerns you've raised about filler and its effects on collagen production are understandable. Here’s some information that might help clarify the situation:

Collagen Stimulation by Fillers:

Some dermal fillers, particularly those containing hyaluronic acid, can stimulate collagen production in the skin. This effect can lead to a more prolonged improvement in the treated area, even after the filler has been metabolized by the body.
Permanent Changes:

While fillers themselves are not permanent, the collagen stimulation they induce can lead to longer-lasting changes in the skin’s structure. However, these changes are typically subtle and shouldn't drastically alter your appearance permanently.
Use of Hyaluronidase:

If you are unhappy with the appearance of your nose due to overfilling, hyaluronidase can be used to dissolve hyaluronic acid fillers. This enzyme breaks down the filler material, and it can help return your nose closer to its original shape.
Consultation with a Specialist:

Given your concerns and the complexity of your situation, it would be beneficial to seek a second opinion from a board-certified dermatologist or plastic surgeon who specializes in facial aesthetics. They can assess your situation and determine the best course of action.
Managing Expectations:

It's important to have realistic expectations and clear communication with your provider about your desired outcomes. Photos from before any fillers were used can be helpful in guiding treatment.
Your situation can likely be improved with the right interventions, so seeking expert advice is an important step.
