The usual frequency is 1 treatment every 15 days (for slimming treatments). In some cases this can be reduced to 10 days by the addition of additional drainage treatment but is not necessarily recommended. There is a physiological reason for this: when apoptosis occurs and some fat cells die, waste is formed. This will be eliminated by natural routes (blood, lymphatic system, and then urine). Metabolism must therefore be allowed to evacuate this waste without overloading the circuits. Toning treatments can be performed once every week.
