Two different ways to tighten skin
"Skin tightening" describes a goal, not a method. Traditional non-invasive tightening delivers energy through the surface of the skin to warm the tissue beneath it. Morpheus8 Body delivers radiofrequency through fine needles, placing the energy at a chosen depth instead of passing it through the surface.
Both aim to stimulate the body's own remodeling response. They differ in how deep the energy goes, how much recovery is involved, and which concerns they suit.
