Beauty Measurement Techniques Using a 2D Spectral Radiometer!! In the evaluation of cosmetics, skin luster, and blemishes, the mainstream method is sensory evaluation through visual inspection. In contrast to such sensory evaluations, quantitative measurements can be achieved by using measurement instruments to quantify the data. Conventional colorimeters can only measure a small part of the skin, making it difficult to detect unevenness, but a 2D spectral radiometer can record images and spectral data of the entire skin, providing examples of quantitative measurements of skin color and cosmetics. 【Examples of Content Included】 ■ Skin evaluation case studies ■ Skin measurement images and spectral reflectance ■ Evaluation of the epidermal layer, including blemishes and pores ■ Foundation evaluation ■ Shine evaluation ■ Skin evaluation under different lighting conditions *For more details, please request materials or view the PDF data available for download.
