This process works with low frequency ultra sound and combines a safe and specific frequency of 517 KHz and an intensity of 110 mW/cm² stimulating the sympathetic nerve system terminals.This stimulation triggers the release of NorAdrenaline (a neuro-mediating hormone) in the adipose tissues, independently from the central nerve control.

NARL is the first scientifically proven technique to induce a natural lipolysis (fat release) through local increase of noradrenaline. The released noradrenaline acts on adipocytes cells activating locally the lipolysis. The Free Fat Acids (FFA) and glycerol resulting in the bloodstream from lipolysis must be eliminated by physical exercise or an equivalent substitute within the 60 minutes following the sonication session.
