Is this the same technique as electrostimulation of the stomach or buttocks?

No! It’s quite the reverse.

Electrostimulation is a very simple, everyday technique which consists of stimulating the muscles using electricity.

Safetox does exactly the opposite, which is technically much more complex. Its aim is to relax the “bad” muscles, not to stimulate them.

It also works by inducing a reflex response in the good (posterior) muscles to restore their dominance.
