What Are Side Effects of Collagen Injection on Nose?

Swelling, bruising, redness. Collagen, hyaluronic acids such as Juvederm and Restylane, and Radiesse are used off-label to raise depressions in the nasal bridge over the bony hump to make a more straight profile or slope. They last for several months.

I recommend agains injecting any fillers on the nose as the skin is very thin, and it may cause irreversible skin damage if injected too superficially.
