Abstract:
본 발명은 피부 각질층의 거칠기를 측정하여 화장품의 피부보습력을 평가하는 방법에 관한 것이다. 보다 상세하게는, 본 발명에 의한 화장품의 피부보습력을 평가하는 방법은 기존의 기기적 측정에 의한 수치로만 표현가능한 피부보습력을, 채취한 피부 각질층을 전자주사현미경으로 관찰한 후 이를 각질세포들이 일어난 비율에 따라 육안판정을 실시하여 피부각질층의 거칠기를 이미지로 가시화하여 평가하는 방법으로서, 이를 통해 일반인들도 화장품의 피부 보습력 평가결과를 쉽게 이해할 수 있다. 피부 각질층 * 거칠기 * 피부 보습력 * 전자주사현미경 * 이미지 * 가시화

Abstract:
A method for estimating the moisturizing effect of cosmetics by measuring the roughness of a stratum corneum is provided to understand the effect of cosmetics by observing the stratum corneum with a scanning electron microscopy and visualizing the roughness of the stratum corneum as images. A method for estimating the moisturizing effect of cosmetics by measuring the roughness of stratum corneum includes the steps of: before applying the cosmetics, collecting the stratum corneum, and observing the stratum corneum with a scanning electron microscopy, observing the ratio of horn cells generated on the stratum corneum from the observation result of the scanning electron microscopy, and expressing the roughness of the stratum corneum numerically; and after applying the cosmetics, collecting the stratum corneum and observing the stratum corneum with the scanning electron microscopy, observing the ratio of horn cells generated on the stratum corneum from the observation result of the scanning electron microscopy, and expressing the roughness of the stratum corneum numerically; and calculating the rate of increase and decrease of the roughness of the stratum corneum.
