I'm considering filler on my nose bridge. How long will it last? Will it dissove into my body?

Without looking at your nose I can't say if you are a good candidate for using filler. I feel that if it is done correctly and certain areas such as building up a low bridge is can be effective and lasts at least a year if not longer. My preference is an HA filler such as Perlane. It is generally not safe to inject the tip or nostrils as damage to the tissue can occur. I would consult a doctor with rhinoplasty experience as doing this is really a form of rhinoplasty surgery with a similar set of potential issues.

these can be done in this area with great results if you are a candidate.  please speak to your dermatologist or plastic surgeon about their recommendations.  Best, Dr. Emer.

Filler placed carefully along the nose bridge,
sometimes referred to as non-surgical rhinoplasty, can be a fantastic
alternative to invasive surgeries. Filler can help enhance the nose bridge in
patients who have little cartilage, or can provide a smoother profile for those
who have “bumps.”

How long the effects of the non-surgical
rhinoplasty lasts will depend on what kind of filler is used. I typically like
to use Radiesse, a robust, calcium-based filler with a density that can work
great for shaping the nose, chin, cheeks, and jawline. Radiesse will generally
last 9-12 months, and like you mentioned, will be gradually absorbed by the
body.

When done correctly, there is very small risk
of side effects outside of bruising and/or swelling. Be sure to consult with a
board certified Dermatologist who is an experienced injector. Best of luck.
