Background: For personalized skin care, noninvasive quantitative methods to evaluate facial skin characteristics are important. Janus‐III is one of the most widely used imaging analysis devices in the skin care industry in Korea. Janus‐III generates values for a range of skin characteristics. Due to the convenience of obtaining results for a variety of skin characteristics in a single measurement, the use of Janus‐III in cosmetic stores and research institutes has been recently increasing. However, the consistency of skin measurements of Janus‐III has not been elucidated yet. Materials and Methods: In this study, we repeated skin measurements three times for 70 different subjects and compared each numerical value in order to assess the consistency of the Janus‐III. For this purpose, we compared between‐sample distances and within‐sample distances. Results: We found important patterns for future analyses in terms of consistency. First, the average values of skin measurement categories were more reliable than individual part values of facial segments. Second, center part values such as forehead and nose were more reliable than side part values such as left and right part segments. Conclusion: If researchers who use Janus‐III for studies of facial characteristics analyze average and center part values first, they can obtain relatively reliable patterns of facial skin characteristics.

The self-cleaning effects of polyethylene terephthalate fabric (PET) through the photocatalytic effects of TiO 2 (T), porphyrin (P) and silane (S) have been explored ultrasonically using bath type (WUC-D22H, Daihan Scientific, Korea). The ultrasonic power and frequency were 100 W and 30 kHz, respectively. The surface modification in fabric was achieved by the ultrasonic deposition of anatase TiO 2 (T), porphyrin (P), and further modification by silane (S) was used to achieve dual-function (photocatalytic and superhydrophobic) self-cleaning behavior. The dye-degrading abilities of the modified fabric surface confirmed by the photo discoloration of various organic pollutants by visible light treatment. From the tested various dye, methylene blue (MB) decomposition was monitored using UV–Vis spectroscopy by measuring the changes in concentrations in the fabric at altered time breaks. The attachment of silane and its stability after washing the surface of fabric confirmed by measuring the water contact angle (WCA). The self-cleaning efficacies were in the order PET@TP > PET@TPS. The modifications are done in fabric surface characterized and confirmed by XRD, XPS, UV–Vis, and FESEM analyses. Fabric's self-cleaning effect examined with common daily life pollutants. Easy to make single-component ink prepared using silane (S) and used as digital printing ink and printed on fabric, exclusively attained hydrophobic surface in the printed area. Unlabelled Image • Dual function self-cleaning behavior attained in PET samples by surface modification via ultrasonic finishing method. • Visible light responsive decomposition of different organic pollutants using TiO 2 and porphyrin. • Single component ink prepared using silane and printed on surface modified fabric to attain superhydrophobic image.
