Abstract: A microcurrent treatment device has one or more electrodes or emitters configured for electrical communication with the surface of a subject's skin. A voltage or current supply is adapted to generate an electrical waveform or other energetic waveform for application to the skin surface, via the one or more electrodes or emitters, and a controller is configured to modulate the waveform. The controller can modulate consecutive pulses of the waveform so that the pulse width, period, frequency, amplitude or integrated amplitude of the consecutive pulses varies in a predefined, random, pseudorandom, or other aperiodic manner, or so that the pulses exhibit a degree of statistical randomness, over a predefined period. The period can cover a set of consecutive pulses defining a treatment cycle, or a continuous subset of consecutive pulses defining one or more phases of a treatment cycle.

Abstract: A method includes applying one or more electrodes to the skin or skin surface of a subject, applying a voltage or current signal to the skin surface via one or more of the electrodes, and modulating the signal to maintain treatment efficacy, or so that the power output can be charge balanced, or both. An agent can be applied to the skin surface during a treatment period defined after the voltage or current signal is applied. Permeability of the skin to one or more components of the agent is enhanced or increased during the treatment period, responsive to the modulated power output. A device for performing the method is also provided.

Abstract: A skin treatment device has one or more electrodes adapted for application of a current to a skin surface of a subject, a voltage or current supply configured to generate the current, and a controller configured to modulate the power output to the skin surface. The controller includes a monitor circuit configured to generate feedback responsive to a change in the power output to the skin surface, based at least in part on the current, and a control circuit configured to modulate the current, based on the feedback.

Abstract: A skin treatment device is provided with a thermally modulated treatment head adapted for contact with a user or other subject's skin. The device includes one or more thermal elements adapted to modulate the temperature of the head, a power source adapted to provide current to the thermal elements, and a controller adapted to modulate the head temperature by controlling the current delivered to the thermal elements. A topical agent can be disposed between the treatment head and the subject's skin, where the temperature of the topical agent is modulated in response to the temperature thereof.

Abstract: Disclosed is a method for treating dermis and hypodermis by placing at least a first electrode at the surface of a to-be-treated skin region and contacting a second electrode at another position on the body to be treated then applying between the electrodes a current with pulse component, said current being sufficient to produce electro-osmotic pressure/velocity wavefronts corresponding to the fundamental frequency in blood vessels in the dermis and hypodermis of the skin region.

Abstract: Devices and methods are disclosed herein apply a fluid to the skin of a human or animal, in particular skin bearing hair or fur. The device comprises an array of hair plow elements, each hair plow element comprising a skin contact surface. Device is adapted to apply a fluid to skin and simultaneously lift any hair or fur covering the skin or hair or fur sprouting from the skin away from the skin so that the fluid is applied preferentially to the skin rather than to any hair or fur covering the skin. Additional embodiments of the device are described comprising a transcutaneous electrical stimulator adapted for supplying a current to the fluid and the skin. Methods of use of the device are also disclosed.
