In this study, facial pore size of vertical length changing from vertically stretched pore to smaller circular pore was investigated to provide basic data for clinical research center develop in pore size measurement method in the future. Vertical length of skin pore was measured by taking pictures of facial site using Visio Face® 1000D at the time before and after the use of the product with the same indoor lightning condition. Taken pictures are analyzed with the Image Pro Plus v7.0 program to evaluate the vertical length of the pore. As a result of analysis, vertical length of the pore was gradually reduced as 9.23±2.34 pixel before product use, 8.17±1.90 pixel immediately after use, 7.44±1.84 pixel after 3 days, and 6.62±1.75 pixel after 7 days. In addition, the number of pore was also gradually reduced as 120.41±51.56 ea before product use, 62.73±50.48 ea immediately after use, 51.05±44.59 ea after 3 days, and 40.32±38.23 ea after 7 days. These results indicate that vertical length of facial pore were investigated by using Visio Face photo and Image Pro analysis and this measurement method may be applicable to evaluate skin pore research and treatment.
