“…Characterization of pores by the above-mentioned methods is limited to pore number, size, shape, and volume. [7][8][9] Masaki et al 13 recently, argued that colorimetric features are also important in pore characterization. However, to our knowledge, no objective method has been established to measure color in and around facial pores in vivo.…”

“…Number of imaging‐based methods has been used in literature to evaluate facial pores in vivo. These include (a) 2D surface imaging (full face imaging or dermoscopic imaging), (b) 3D imaging (in vivo skin or skin replica), and (c) confocal laser microscopy . In these methods, pores are numerically evaluated by visual grading and/or image analysis algorithms.…”

Background Visible facial pores are an important cosmetic concern especially among young females. Number of different methodologies is used today to assess facial pores and efficacy of technologies. Main limitations of these methods are, however, (a) moderate correlation with visual perception, (b) characterization is mostly limited to size or number of pores, (c) measurement is limited to a smaller area of face, and (d) operational difficulties. In order to address these limitations, we developed a 2D image analysis tool to assess and characterize visible facial pores. Materials and Methods Two clinical studies were conducted with northeast Asian skin type females. In the first study, 40 subjects age between 20 and 40 with different degree of pore severity were recruited. In the second study, 15 subjects age between 20 and 40 with enlarged pores were recruited to evaluate pore product efficacy. In both studies, full face images were taken using Visia‐CR and assessed by means of the newly developed tool and visual grading. Results A high correlation between visual grading and pore size was obtained (r = 0.86). New methodology was able to differentiate products similar to visual grading. Conclusion Novel pore image analysis method using 2D skin surface imaging with standard photography has been developed and validated. In addition to pore size measurements, we propose this method to be used to measure pore shape, color, and orientation for a comprehensive characterization of facial pores.

“…Results also show that regardless of the variations in density of pores in the different ethnic groups we studied, 15 an increased pore density correlates with the presence of enlarged pore. Another parameter that was also known to be associated with enlarged pore is the elongation of pores 16‐18 . Even if we did not study the age‐related increased elongation of enlarged pores, we show that a strong correlation exists between more elongated shapes and the enlargement of pores.…”

Pores are apertures at the surface of a tegument that enable input or output of gases or fluids. Therefore, stricto sensu, pores of the skin correspond to the outlets of the eccrine sweat glands and of the pilosebaceous units. Sweat glands are relatively simple structures with an outlet of 5-10 µm in diameter. 1 Pilosebaceous units are more complex. They consist of the hair follicle, located deep in the dermis, arrector pili muscles, sebaceous gland, and the hair shaft. Their outlet is, normally, 40-80 µm in diameter. 2 Under certain circumstances, the outlet of the facial pilosebaceous units can greatly enlarge, leading to the formation of conspicuous cuvettes that confer a "golf ball"like aspect to the skin and that are called pores by laypeople. 3 These visible structures are benign, but a cosmetic defect of most concerns for people affected. Still, studies on enlarged facial pores are sparse. In addition to the studies we refer above

A method of evaluating facial pores using optical 2D images and analysis of age‐dependent changes in facial pores in Koreans

Abstract: A new evaluation method using 2D optical images facilitates the analysis of pore distribution and elongation throughout the entire cheek. This is an improvement over an analysis of pores over a narrow region of interest.
