Bipolar (two-electrode) 450 KHz radio waves emit electrical impulses, and the main proteins in the skin (collagen and elastin) absorb them. Collagen and elastin fibers (fibrils) are curled and shortened when exposed to radio frequency. This makes the skin stronger and firmer and the altered collagen activates fibroblasts, cells that stimulate natural collagen production. Thermal exposure increases the permeability of cell membranes, better absorption of active ingredients, oxygen, improves blood circulation, promotes muscle relaxation and recovery, eliminates pain, smoothes and tightens the skin, has an anti-inflammatory effect.
