Hi Tarzana. Radiesse will dissolve in the body over time. 1 year is typical for the duration of the injections.
Lumps and bumps are not common for an experienced injector, but some movement of the product may be necessary after initial injection to smooth the area. If a harder bump develops some time after injection, this can be a more serious side effect and you should see your injector immediately.
Even though it is not well accepted to inject Radiesse into the lips or under the eyes, we continue to see patients with these areas injected call our office. If your injector proposes to use Radiesse in the area immediately under the eye or in your lips, you should find a new injection professional.
