Fast metabolism and Radiesse - Is it true my body may be absorbing the product faster than others?

In my practice every cosmetic patient is addressed separately as there are no "cookbook" approaches though after almost 20 years of filler experience I have seen some patients not have a prolonged effect but this is  uncommon. We use many different fillers in the same patient to achieve a optimal correction. I would recommend you discuss with a dermatologist board certified and experienced in fillers in your area.

I have much success with Radiesse and certainly have never put 8 syringes into the same person in a year's time. With that being said, you cannot "water down" Radiesse. The syringe is pre-filled and there is not a way to take it out or add another solution in that waters it down. It's not like Botox where the injector mixes the product and pulls it out of a vial. So there's not a way to do that. You could have a fast metabolism, I suppose, but 8 syringes in less than a year says that either your injections aren't being done in a correct location or depth, or you simply need a different kind of filler used.
