Abstract

The evaluation for the visage volume was performed with human and dummy face using PRIMOS $body^{(R)}$. Three researchers measured the dummy face attached different volume of clay (6.6 mL, 13.2 mL, and 19.8 mL). It is identified that the high correlation between measured values and real volume ($R^2=0.99$). The percent (%) of relative standard deviation (RSD) of the data was shown below 10%. In Gage R&R analysis, the percent of contribution, the percent of study variation and distinct categories values were 0.78%, 8.85%, and 15% respectively. Therefore this method was regarded as the good standard condition in aspect of reproducibility and repetitiveness of data. The face volume variation was measured by PRIMOS $body^{(R)}$ on the face in participated 10 healthy Korean women volunteers. Subjects used the product once a day for two weeks as night sleeping pack. After application of the test products, the 3D image data of face were taken 1 and 2 weeks later. We found the face volume was significantly decreased after using products. In conclusion, this novel non-invasive technique was useful in measuring and visualizing alterations in face volume as a consequence of certain treatments. This system will provide a rapid and precise analysis of 3D topographical information for face.

PRIMOS $body^{(R)}$ 기기를 이용한 얼굴부피 평가법 개발에 관한 연구를 진행하였다. 평가법의 신뢰성을 확인하고자 세 명의 시험자가 마네킹과 사람을 대상으로 얼굴 부피를 측정하였다. 마네킹의 얼굴에 여러 가지 부피의 찰흙을 붙이고, 기기로 얼굴을 측정하였는데, 실제 찰흙의 부피와 측정값 사이에 높은 상관성($R^2=0.99$)이 있는 것으로 나타났다.% RSD와 Gage R&R 분석으로 기기의 정확성, 반복성, 재현성을 확인한 결과 신뢰성이 있는 결과를 얻었다. 이와 같은 평가법을 얼굴 붓기 감소에 영향을 주는 화장품의 효능을 평가하는데 적용하였다. 10명의 건강한 여성을 대상으로 화장품 사용 전후 얼굴의 부피를 측정한 결과, 얼굴의 부피가 감소하는 것으로 나타났다. 이와 같은 결과를 통해 PRIMOS $body^{(R)}$를 이용한 얼굴 부피 평가법은 인체평가에 유용하게 사용될 수 있을 것으로 보인다.
