The present invention relates to a customized LED light irradiator according to the skin analysis. The present invention is to set the location on the skin and measure the location by the skin diagnostic device (D) for transmitting and receiving by wireless communication with a smart phone, and the skin information measured by wireless communication from the skin diagnostic device (D) and measure for each location Diagnosis and prescription for one skin information, and a smart phone (A) with an app mode that implements a function for controlling the LED light of the wavelength band according to the prescription and the skin for each location The control unit (F) for irradiating and controlling the LED (LED) light by transmitting and receiving the LED (LED) light information of the wavelength band according to the prescription for the state by a wireless communication from a smart phone (smart phone), the control unit ( F) is a wireless module (WIFI, BT) 200 for transmitting and receiving prescription information by the skin diagnosis for each position (coordinate) of the skin from the wireless communication unit (WIFI, BT) of the smart phone (smart phone), and the wireless module (WIFI, BT) (200 ) And a microcomputer 201 for transmitting, receiving, processing and controlling information signals, and an LED drive 203 for turning on / off a light emitting diode (LED) by a signal command of the microcomputer 201. ), And a power supply unit 204 for supplying power to the microcomputer and the LED drive, and is turned on / off by a signal command of the LED drive 203 and generates a plurality of light rays by wavelength band. The light emitting diode (LED) 202 to be irradiated and the light emitting diode (LED) 202 are installed in the mask 206 as a plurality, but are configured in the mask 206 The light emitting diode 202 is configured to be distributed according to coordinates, and each coordinate 207 is a customized LED light irradiator according to skin analysis, w
