Dermal fillers and diminished vascularity - how common is this?

Many of my colleagues have reported concerns about deep scarring and decreased vascularity during facelift in patients who have had multiple nonsurgical procedures - this is more likely with Sculptra, and treatments like RF microneedling, targeted ultrasound etc than with remote HA filler. I would not personally lift a facelift flap encompassing a region of current HA filler due to vascularity concerns. If you are considering facelift I recommend to my patients dissolving all fillers first and give the tissue at least 4-6months healing time prior to proceeding with the surgery in try to minimize the risks.
