Sebum is emitted by skin pores, the openings of sebaceous glands. Skin pore size increases due to excessive sebum emission and decreased skin elasticity caused by aging. These larger skin pores result in cosmetic problems. Therefore, methods to regulate skin pore size were examined. Additionally, effective methods for measurement of skin pores are also needed. In the present study, we developed a novel quantitative method for evaluation of skin pore area and degree of aging using the Image J software. First, we evaluated the pixel size of skin pores following the application of pore-tightening cream to the skin using the Cosmetic Full-Face Photography System, which is used to measure skin pore size, as well as a novel system that combines both microscopy and Image J analysis. In both the Cosmetic Full-Face Photography System and the novel system, skin pore size decreased following application of pore-tightening cream; however, the novel skin pore detection system effectively determined the decreases in skin pore size. Additionally, the degree of aging of skin pores was determined using Feret’s diameter. Thus, we suggest that this novel skin pore-detection system can be utilized as a substitute for the existing skin pore-detection method.
