01 / Radiofrequency
Radiofrequency (RF)
Radiofrequency sends a high frequency current through the skin. The skin's resistance to that current produces controlled heat in the dermis, the layer where collagen and elastin live. That warmth is what prompts the look of firmer, tighter skin over a course of sessions. RF is the modality most associated with clinic skin tightening, and the one most at-home brands build their flagship around.
