You can use the device in one of four ways after applying your favourite serum and moisturiser (no need for a conductive gel!): Booster mode (Electroporation): The Booster mode uses Electroporation to create temporary passageways into the skin and allow active skincare ingredients to penetrate deeper for maximum, glow-boosting effectiveness. Studies show this mode to increase skin permeability. MC mode (Microcurrents): The MC mode helps to volumise and plump up the skin, softening the appearance of fine lines and wrinkles around the eyes and mouth. Studies show this mode improves forehead volume and helps soften the appearance of wrinkles. Derma Shot mode (EMS): The Derma Shot mode helps to firm and define skin by stimulating the facial muscles with mid-frequency EMS. Air Shot mode (Electric needles): The Air Shot mode helps to improve pore elasticity by creating non-damaging passageways into the skin with electric needles.
