기계적 평가와 이미지를 이용한 얼굴의 번들거림과 윤기의 분류 기준의 연구 The Differentiation Criteria between Greasiness and Shininess on The Face Using Mechanical Evaluation and Image원문보기
얼굴 피부는 신체 건강을 표현할 뿐만 아니라 매력을 결정하는 요소 중 하나이다. 특히 윤기 나는 피부는 대부분의 사람들이 선호하며 윤기 나는 피부 표현을 위해 다양한 화장품들이 만들어져왔다. 하지만 윤기 있는 피부는 주관적 평가이기 때문에 기름진 피부의 경우 기존의 피부 윤기 평가 방법으로는 명확한 윤기 있는 피부로 평가하기가 어렵다. 더욱이 윤기와 유사하게 광이 있지만 부정적으로 평가되는 번들거리는 피부와 명확한 분류 기준 또한 없는 상황이다. 본 연구에서는 피부측정 파라미터 5개[피부 광채, 피부 보습, 피부 투명도, 피부 피지, 안면 이미지]를 측정하였고, 연구대상자들이 촬영된 안면 이미지를 근거하여 각각의 윤기 있는 피부와 번들거리는 피부의 이미지를 선별하여 피부 측정의 정량화를 통해 비교 분석하였다. 그 결과 번들거리는 피부에서 피부 광채 및 피지 증가, 투명도 감소, 보습 감소를 확인하였다. 그러나 윤기 있는 피부의 경우 피부 광채, 피지, 투명도는 유사한 패턴을 보였지만 보습이 유의차 있게 증가하는 결과를 보였다. 본 연구에서는 기기측정 및 정량적 평가를 통해서 윤기 있는 피부와 번들거리는 피부를 분류하는 객관적 평가 기준을 제시하고자 한다.

The facial skin condition expresses physical healthy as well as is considered one of important factors for attractiveness. Especially, most people prefer shiny skin. So various cosmetics has been manufactured for expression of shiny skin. However, shiny skin is subjectively evaluated, and difficult to evaluate clear shininess using the existing method in oily skin. Moreover, there is no clear classification criteria between shininess and glossiness, which is assessed negatively in the skin. So there has not been a reference value by mechanical measurement to define and classify shiny skin from greasy skin. In this study, we measured skin biophysical parameters (gloss, hydration, translucency and sebum) and facial images which are selected by volunteers using sensory evaluation. According to the measurement results, the values of gloss, sebum, and translucency were similar in both shiny and greasy skin; the values of sebum and gloss increased, whereas those of translucency decreased. However only skin moisture values statistically increased in shiny skin. In conclusion, we propose objective assessment criteria for classifying shiny and greasy skin using device measurement and quantitative assessment.

문제 정의
Numerous studies have evaluated skin quality of greasiness and shininess[3,5,9]. Greasy skin has been traditionally evaluated by the amount of sebum secretion and a visual assessment scale based on a survey. Shiny skin has been measured by the intensity of skin surface reflection.
The aim of this study was to differentiate shininess from greasiness. We conducted experiments through sensory evaluation of images, measurements of various skin biological parameters, and analysis of images.
제안 방법
However, the study required to measure with more detailed measurement such as measure directly from stratum corneum in order to exclude all the possibilities that affects corneometer’s the capacitance in shiny and greasy skin.
In this study, sensory evaluations and image analysis were performed using images captured by VISIA-CR (Canfiled Imaging System, USA). The photographs were obtained using parallel-polarization mode at each time point.
In this study, we measured skin hydration, sebum, gloss, and translucency levels and took the volunteers facial images four times over the course of six hours. We had volunteers look at their facial images and select those where they thought their skin looked greasy or shiny.
To measure skin translucency, subsurface reflection was acquired on the cheek by Translucencymeter (TLS850, Diastron Ltd, Andover, UK). The instrument measures the reflected light from the transmitted RGB LED beam to the skin. It calculates transparency values by using side- and back-scattered light.
The measurements and photographs were obtained at baseline (T0: at 30 min after washing the volunteer’s face) and at 1 (T1: at 1 h after washing the volunteer’s face), 3 (T3: at 3 h after washing the volunteer’s face), and 6 (T6: at 6 h after washing the volunteer’s face) h after washing the face using the same cleansing form.
This instrument calculates the amount of sebum per unit area (µg/cm2) by placing an absorption tape on the skin and measuring the amount of sebum the tape absorbs using a photometric reflection method.
대상 데이터
Korean female volunteers (N = 20, aged 20-33 years old, average age; 27.10 years) participated after signing the informed consent. The criteria for participation were: not having skin disorder, not being the period of lactation or pregnancy.

Additional study is required to investigate the correlation skin types and evaluation of shiny and greasy skin using large number of volunteers with various age and skin type. we propose a further study for establishing the visual-grading standard of greasiness on skin through image analysis and mechanical evaluations.
Additional study of correlation skin types to evaluate of shiny and greasy skin is required using large number of volunteers with various age and skin type. Also, we propose further study to establish the visual-grading standard of greasiness on skin through image analysis and mechanical evaluations.
Therefore, we assumed that the optimal ratio of sebum to moisture level on facial skin exists when the skin looks shiny. Further research is required to investigate the appropriate ratio, because the sample size of this study was small. Furthermore, we observed that skin translucency is not a key factor in differentiating greasiness from shininess.
But there is a fact that we cannot exclude is, the sebum and hydration level is changed depends on the age and the skin type of volunteers and this will affect the shiny and greasy skin measurement value. Therefore, the further study is needed to see whether it gives the same results or not in different skin types to compare with this study.
