In Monopolar RF devices, the poles are located quite far apart from each other usually the “inactive pole” (or grounding pad) is placed at the back of the body, while the “active pole” (which is the applicator used on the target area) is used over the target zone. As a result, the current has no other choice but to traverse through ALL the skin layers after entering the skin, travel through the body to the other pole, and exit there.

This means that with monopolar RF, and depending on some other factors too, we can treat not only the skin surface (epidermis) but also the middle skin layer (dermis – responsible for skin tightening), the deepest skin layer (hypodermis – where our cellulite is formed) and even the subcutaneous fat deposits below the skin itself.
