Effects of Tool Shape on Facial Contour Reduction in Middle-aged Women in Their 50s and 60s

Abstract

Purpose: This study aimed to evaluate the effect of tool-based facial care on face size reduction in middle-aged women and to analyze the differences in effectiveness by tool form.Methods: The study was conducted with 14 middle-aged women in their 50s and 60s who volunteered to participate at a P aesthetic shop in Gangnam-gu, Seoul. The participants were divided into three groups: Group A (11 participants) received treatment with a meridian-scraping-shaped tool, Group B (4 participants) received treatment with a plain tool, and Group C (3 participants) was untreated. Group A underwent treatment twice a week for a total of six sessions with the meridian-scraping-shaped tool. After a year, some participants from Group A were reassigned to Group B for further care with the plain tool. Face sizes were compared over time by measuring 14 variables, including length, width, and jawline length. Data were analyzed using Kruskal–Wallis and Friedman tests.Results: In Group A, there was a significant reduction in most facial areas, particularly in face width and jaw width (<i>p</i><0.001). In contrast, Group B showed significant reductions in only some areas, while no changes were observed in the control group. This study found that the meridian-scraping-shaped tool was more effective in reducing facial contours than the plain tool.Conclusion: This study demonstrated that the meridian-scraping-shaped tool, which applies the leverage principle, was more effective in reducing facial contours in middle-aged women compared to the plain tool. The shape of the tool has a critical impact on treatment outcomes.
