Abstract: We describe devices, methods, and systems used for hair removal. In particular, we describe hair removal devices, particularly epilation devices, methods of using those devices, and systems including those hair removal devices. Our hair removal devices include, in combination, a.) at least one primary energy source that applies that energy, e.g., radio-frequency (RF), high intensity focused ultrasonic (HIFU) energy, or high intensity light, e.g., intense-pulsed light (IPL) or light from flash lamps or lasers, to the skin or to hair in a continuous, semi-continuous, or pulsed mode and b.) a hair removal component or components, such as rotary mechanical hair removal structures or epilators, that perform a mechanical hair removal step. Auxiliary treatment or control components such as comparatively lower power heaters, ultrasound devices, coolers, impedance measurement devices, etc. may also be included in the combination or used in conjunction with our combination device.
