Disclosed is an apparatus for measuring skin color. The apparatus for measuring skin color comprises: an RGB light source sequentially projecting a red light, a green light, and a blue light； a detecting unit detecting incident light which is produced after the red light, the green light, and the blue light sequentially projected are reflected by skin, so as to measure a skin color measurement value including a red color measurement value detected corresponding to the red light, a green color measurement value detected corresponding to the green light, and a blue color measurement value detected corresponding to the blue light； and a control unit primarily correcting the skin color measurement value based on the white-black brightness range, and secondarily correcting the corrected skin color measurement value based on a color correction filter function, thereby calculating a final skin color measurement value including a final red color measurement value, a final green color measurement value, and a final blue color measurement value. Here, the control unit produces a least-square function that minimizes a least-square error among a second reference red color measurement value, a second reference green color measurement value, and a second reference blue color measurement value, which are produced after each of a plurality of reference color sheets is measured by using a first reference red color value, a first reference green color value, and a first reference blue color value, which are set at each of the plurality of reference color sheets, as well as the RGB light source and the detecting unit. Furthermore, the produced least-square function is used as a color correction filter function.COPYRIGHT KIPO 2019피부 컬러 측정 장치가 개시된다. 피부 컬러 측정 장치는 적색광, 녹색광 및 청색광을 순차적으로 조사하는 RGB 광원과, 순차적으로 조사된 적색광, 녹색광 및 청색광이 피부에 반사되어 입사되는 광을 감지하여 적색광에 대응하여 감지되는 적색 측정값, 녹색광에 대응하여 감지되는 녹색 측정값 및 청색광에 대응하여 감지되는 청색 측정값을 포함하는 피부 컬러 측정값을 측정하는 감지부와, 제어부는 피부 컬러 측정값을 일차적으로 화이트-블랙 명도 범위를 기준으로 보정하고,
