Can radiofrequency based tightening procedures “melt” fillers?
There is really no scientific data or studies on this but it would depend on the level in the dermis that the filler was placed. If the filler is placed (like Sculptra) below the dermis (the layer with all the collagen, etec.) then the radiofrequency shouldn’t affect it.
Some fillers like Restylane, Juvederm or Belotero may be placed high in the dermis or even at the dermal-epidermal (barrier layer) junction, and then it’s possible the heat generated from the radiofrequncy could affect it.
