Radio Frequency uses radio waves directed through a probe head which is rested onto the skin. The radio waves are directed at the skin to produce a heating effect. The energy penetrates the skin layers to selectively heat the skin tissue and the extracellular matrix where the collagen fibers are embedded. The local heating causes an immediate contraction of collagen fibers, and at the same time increases the metabolism of the fibroblasts thereby accelerating the production of new collagen and elastin fibers.
Skin Tightening targets the deeper layers of skin, heating them up. This creates stimulation of the skin and in particular, the collagen, a substance which gives elasticity to the skin. This causes water molecules in the deeper layers of skin to vibrate. This creates friction which causes the heating effect. When heat is applied to collagen fibres, they shrink and tighten up, and over time following the treatment, new collagen also forms.
