Purpose: For minimally invasive procedures, three-dimensional (3D) anatomical knowledge of the structures of the face is essential. This study aimed to describe the thickness of the skin and subcutaneous tissue and depths of the facial muscles located in the infraorbital region using a 3D scanner to provide critical clinical anatomical guidelines for improving minimally invasive cosmetic procedures. Materials and Methods: The 3D scanning images of 38 Korean cadavers (22 males and 16 females; age range: 51~94 years at the time of death) were analyzed. Eight facial landmarks (P1~P8) were marked on the cadaveric faces. The images were scanned in three steps-undissected face, hemiface after skinning, and revealing the facial muscles. Student's t-test was used to identify significant differences. Result: The skin and subcutaneous tissue tended to become thicker from the upper to lower and medial to lateral aspects, and the muscles followed the same pattern as that of the most superficial located muscle and the deepest located muscles. No significant sex-related differences were found in the skin at any landmark. However, the muscles tended to be deeper in the female participants. Conclusion: The study data can serve as a basis for creating or enhancing clinical anatomy-based guidelines or improving procedures in the infraorbital region.

The purpose of this study was to investigate the effects of desensitization and flooding on the behavior of dogs during grooming, focusing on their response to the sound and skin stimulation while using a clipper. A total of 20 adult dogs over two years of age with complete personality formation were included in the study. Ten dogs, of which three were Bichons (average weight 5 kg), four were Poodles (average weight 5 kg), and three were Malteses (average weight 4 kg), were subjected to the desensitization process. The remaining 10 adult dogs were subjected to the flooding experiment, and were of the same breed and average weight as the adult dogs used in the desensitization process. The desensitization and the flooding were performed three times a day (approximately 1 min per session) for 10 days. For desensitization, statistical significance was observed only on the fifth day, when compared by breed (p<0.05). Overall, when compared by measurement day, the results of desensitization for Bichon, Poodle and Maltese dogs were statistically significant (p<0.05). The results for the Bichon, Poodle, and Maltese dogs that were subjected to flooding were found to be statistically significant (p<0.05). There was a significant difference in the results of the flooding on the second and ninth days (p<0.05); however, flooding had no effect on the other days (p>0.05). Desensitization using the clipper, a beauty tool, was faster than flooding in achieving stabilization. In conclusion, desensitization and flooding showed positive results on the stress relief and emotions of dogs during grooming, with respect to cosmetic fear response.

Hyaluronic acid (HA) is a mucopolysaccharide, occurring naturally in living organisms. It is one of the most hydrophilic molecules, so it has been known as being related to skin hydration and skin aging. The purpose of this study was to examine the effects of Cimicifuga heracleifolia ethanol extract on the hyaluronic acid synthesis and the inhibition of hyaluronidase activity. To determine cytotoxicity, hyaluronic acid synthase 2 (HAS2) gene expression, HA production and, hyaluronidase inhibitory effects, 3-(4,5-dimethylthiazol-2-ly)-2,5-diphenyl tetrazolium bromide (MTT) assay, real time - polymerase chain reaction (RT-PCR), hyaluronic acid enzyme linked immunosorbent assay (HA-ELISA), and hyaluronidase assay were used, respectively. When the Cimicifuga heracleifolia extract was treated in the HaCaT cells up to 500 ㎍/mL concentration, cytotoxicity was confirmed by the Cimicifuga heracleifolia extract at concentrations above 200 ㎍/mL. Therefore, the optimum concentration of all experiments used in this study was determined to be 200 ㎍/mL. HAS2 gene expression increased by Cimicifuga heracleifolia extract in a concentration-dependent manner at all treatment concentrations. The production rate of HA was tended to decrease at the highest concentration of 200 ㎍/mL. The hyaluronidase activity inhibition effect of Cimicifuga heracleifolia extract was very high compared to the control group. Based on these results, Cimicifuga heracleifolia extract was expected to have a moisturizing effect on human skin and special attention should be paid to the determination of the concentration of Cimicifuga heracleifolia when developing cosmetic materials using it.

Objective: High frequency wave has been used in cancer treatment and cosmetic area but not in musculoskeletal pain yet. The purpose of this study is to evaluate temperature distribution according to depth and confirm safety of high frequency wave through animal study. Method: High frequency wave was applied to the posterior limb of 9 Sprague-Dawley rats for 20 minutes (experimental group) and no wave was used in the same number of rats for control group. Tissue temperature was measured from skin surface to 1 cm depth (surface, 1 mm, 5 mm, and 1 cm) for 5 seconds. Results: In the experimental group, temperature was elevated 3.2℃ at skin surface, 2.87℃ at 1 mm, 2.25℃ in 5 mm, and 1.74℃ in 1 cm depth. These were significantly different from those in the control group (p<0.001). There was no bulla or redness in the skin after high frequency wave stimulation and neither change of myocytes nor collagen degeneration was found in the tissue histology. There was no apoptosis in the skin surface and muscle layer in TUNEL assay. Conclusion: High frequency wave elevated tissue temperature from the skin to muscle layer without both histologic change and apoptosis.
