Radiesse the long lasting filler.
It’s quite impressive because much like other fillers it gives instant results but over time stimulating collagen production for a longer period of time than Restylane and far longer than collagen. Radiesse is composed of calcium hydroxylapatite suspended in a water based gel.
This is the same material found in tooth enamel and bone. The uses are vast from non-surgical rinoplasty to lifting cheeks to helping bring back your voice.
I would say avoid lips and under the eye area as it’s a relatively firm filler and is meant to be used ideally around firmer bonier areas.
Personally I have a deviated septum and have never considered surgery to correct it. Because it does not affect my breathing in any way and therefore purely cosmetic I would choose a filler such as Radiesse, there is no recovery time, and far cheaper and safer than surgery. My only suggestion would be to perhaps try short-term filler just in case you don’t like the result and have to live with it for up to 18 months or more.
