How to use: The device is an over-the-counter hand-held device intended for the temporary reduction in the appearance of mild to moderate facial wrinkles and firmer skin. The device is only suitable for private use and not for commercial purposes. Any use other than that described in these operating instructions is not permitted. Safety warning! The device protects your skin from overheating. Thermal sensor and heat stabiliser: These measure the skin temperature, stabilise the heat energy and prevent overheating. When the skin temperature reaches 42 – 43°C, the stabiliser will automatically stop emitting heat, until the skin temperature lowers enough for the stabiliser to resume heating. Movement sensor: Only emits RF energy when you are moving the device over your skin.
