Development of Scale Factors for Skin Type Classification

There are no global standards for the classification of skin types and consistency results is low. It necessary to develop a consistent type method that takes into account innate characteristics. First, concepts important related terms were established using Delphi techniques from which factors derived. Second, we derived relative importance complex weight between each factor AHP techniques. The research found priorities in order ‘Oil moisture levels’, ‘Sensitivity level’, ‘Elasticity ‘pigmentation level’. Meanwhile, among 33 detailed scale classification, ‘sebum mass’ was 1st ‘pore size’ 2nd. This study different previous studies weights quantitatively derived, centered on factors. has limitations such as lack experts who participated surveys. However, by deriving key measurement classify type, beauty industry workers can use systematic criteria effectively care purposes relatively short period time.
