Skin care unit

A multi-functional skin care device is provided to emit LED type ultraviolet rays by wavelengths and to generate far-infrared rays and ultrasonic waves through one unit and therefore to help a user to get benefits from diverse skin care functions. A multi-functional skin care device includes: at least one infrared ray LED(210) to radiate infrared rays by wavelengths; at least one UV LED(212) to radiate 200-400nm wavelength ultraviolet rays; a vibrator(230) to generate vibration effects; a second sensor(310) disposed between the infrared ray LEDs and the UV LEDs to switch operations of the infrared ray LEDs, the UV LEDs, and the vibrator according to a given control sequence; and a first sensor(300) disposed between the infrared ray LEDs and the UV LEDs to detect a current state of the skin and to send out the detection value to a controller to execute a suitable skin care program.
