3 months after Radiesse in the cheeks and I don't see any results - should I continue waiting? (photos)

Hi! Do you happen to know how much product was used in your cheeks? It's possible that you may need additional product to notice a result and collagen buildup. I would go back to your doctor to see what he recommends as far as product amount. If you wanted to stay away from injectables, doing a treatment such as morpheus8 will help to lift and tighten the cheeks. Morpheus 8 uses microneedling to help skin texture/tone and radio frequency (RF) to help tighten and lift the area being treated. Downtime is about 3 days, and it is important to avoid direct sunlight for 2 weeks prior and 2 weeks after.

I'm not quite sure what the reservation here is regarding HA fillers, but an appropriately robust lifting filler can not only lift and contour the cheeks, but secondarily may additionally improve tear troughs and hollows under the eyes and diminish smile lines when properly injected by an experienced, board certified cosmetic dermatologist filler expert. What's more, the results of such a treatment are typically immediate, i.e. seen on-the-spot, and may last between 12-18 months.
At least from the question, it sounds like the Radiesse here was used, likely diluted or super-diluted, as a biostimulatory agent, rather than as a filler, since Radiesse undiluted would be expected to yield immediate results (while diluted Radiesse, as a biostimulatory agent, would be expected to take several weeks for results to become evident).
As an aside, a additional advantage of using HA fillers is that they can be dissolved (should the need arise), whereas Radiesse, like Sculptra, has no specific effective dissolving enzyme.
Hope this helps and best of luck. .
