METHOD OF MEASURING AND EVALUATING QUALITY SENSATION OF SKIN, AND USE OF COMPOUND SHOWING EFFECTIVENESS BY THIS METHOD

摘要

PROBLEM TO BE SOLVED: To establish a simple method for measuring the quality sensation of the skin to clarify a theory for making it look younger, and to provide a method for evaluating a quality of skin. SOLUTION: In the method of evaluation, a combination of an incidence angle and an acceptance angle is varied to multilaterally observe a surface reflected light component of the skin, and the difference between surface reflected light components in a specific incidence angle and acceptance angle of the skin of a young woman and that of the skin of an middle-aged or old woman is used as a degree of aging of skin in a quality sensation.
