Will having Venus Legacy treatments after Radiesse injections, around the jaw line/jowls diminish the Radiesse faster?

I have not seen this to be the case, if anything, it will cause the calcium microsphere to interact with the activate collagen producing cells to product more lift/collagen.  I think it cannot hurt.  I frequently do laser right over radiesse without any complications.  Best, Dr. Emer.

Fillers are injected at much deeper layers than the Venus Freeze or Legacy goes. I have never had any issues with doing fillers and Venus Freeze together. The only thing I suggest is that people wait a minimum of 24 hours after fillers for their next treatment. "This
