Acne treatment device using electrical stimulation

Microcurrent-based skin permeation enhancement device for acne treatment

This technology is an acne treatment device consisting of a pair of skin-attachable pads and a control module that sets the microcurrent, frequency, and stimulation time. By applying a bio-level micro-constant current at a specific frequency, it helps acne medication applied to the skin absorb more effectively.

Acne treatments have traditionally included antibiotics, injections, chemical peels, and lasers, but these often come with side effects such as antibiotic resistance. While patch kits that generate nano-currents via potential differences between metals have been proposed, they have limitations in adjusting stimulation intensity and duration to suit individual user needs.

This technology uses a current generator and a frequency generator to output micro-constant current and frequency waveforms to the pads based on control module settings, with a keypad for incremental adjustments to current, frequency, and time. By applying repetitive stimulation with bio-mimetic currents that cause little to no muscle contraction or discomfort, it can reduce the side effects of chemical treatments while promoting inflammation relief. It can be applied to dermatological auxiliary equipment and home skincare devices, serving as a non-pharmacological aid to enhance the efficacy of existing acne treatments.

Key Features:

• A pair of pads attached to the skin around acne lesions and a control module that regulates the pads based on set microcurrent, frequency, and operating time. A current generator that outputs micro-constant current waveforms to the pads and a frequency generator that outputs frequency waveforms based on the control module's microcurrent setting data. A control module equipped with a keypad for incremental adjustments within the ranges of 1–60Hz frequency, 10–100µA microcurrent, and 0.5–1 hour duration. A pad configuration in the form of a patch or tape coated with adhesive conductive hydrogel, attached to the left/right or top/bottom of the lesion.
