1. An adaptive transdermal iontophoresis introduction system in a beauty field, wherein the system comprises:
an electroosmotic iontophoresis system, wherein the iontophoresis system is in contact with skin, and repulses an active agent to a skin layer through action of current or voltage outputting by an electrode driving system, thus realizing a purpose of transdermal iontophoresis into the skin;
a control and drive electronic system, wherein the control and drive electronic system comprises:
an operating system, wherein the operating system comprises a power supply; a power switch; and a mode selection button;
a central processing system, wherein the central processing system dynamically calculates and adjusts an output electrode driving waveform based on one or more basic parameter and, one or more feedback signal of a sensing system, then provides the output electrode driving waveform to the electrode driving system, wherein the electrode driving waveform is alternating current, and the central processing system comprises an integrator to integrate the alternating current waveform and record an outputting total charge;
the electrode driving system, wherein the electrode driving system generates a driving current or voltage according to the output value of the central processing system; and
the sensing system, wherein the sensing system senses conditions of the contacted skin and feeds back to the central processing system in order to dynamically adjust and optimize the electrode driving waveform based on sensed conditions and feedback signals, and wherein the sensing system comprises a skin sensor, a signal conditioning circuit and an analog-to-digital converter,
wherein the skin sensor comprises a skin moisture test sensor, a pH sensor, a sebum measurement sensor, a temperature sensor, and a biological resistance analysis sensor.
