My go-to is the Radiesse-HA Hybrid due to it's real feel texture, density, bulk, and longevity. It seems to have a high patient satisfaction rate. I've had patients try different combinations but they tend to prefer the hybrid. For those who may not be comfortable with Radiesse for whatever reason, HA + PDGF is the next best thing since it is biostimulatory and leads to collagen formation.
No. All of my photos are with hybrid filler. The only times I used HA + PRP/PDGF are with those patients who had PMMA or an unknown filler that may not be compatible with Radiesse.
