摘要

Traditional methods for evaluating skin aging, such as descriptive grading and visual imaging, are limited to surface layers. Assessing deeper layers, such as the dermis and subcutaneous fat, currently requires invasive techniques like skin biopsies. Non-invasive, quantitative approaches for evaluating deep-layer skin aging are essential for both clinical dermatology and cosmetic applications. Shear Wave Elastography (SWE) is an emerging ultrasound-based technology that measures tissue stiffness and is already used for assessing dermatologic conditions like skin tumors and scleroderma. However, its application in skin aging evaluation remains new. To evaluate the effectiveness of SWE in assessing skin aging, and to establish a non-invasive, quantitative method using SWE for clinical and cosmetic dermatology. Eighty medical records in outpatient of Cosmetic Dermatology were selected by convenience sampling, divided into two age groups: Young (20–30 years) and Senior (60–70 years). Skin aging was first graded using the Glogau photoaging scale. SWE was then used to measure skin stiffness. Correlations between SWE-measured skin stiffness and Glogau aging grades were analyzed to assess the potential of SWE for facial skin aging evaluation. A significant positive correlation (r = 0.622, p < 0.001) was found between Glogau aging grades and SWE-measured skin stiffness. Higher Glogau grades were associated with increased skin stiffness, indicating that SWE measurements align with visually assessed skin aging. In female subjects aged 20–30 and 60–70 years, SWE technology proves to be an objective assessment tool for the quantification of skin stiffness, demonstrating significant differences between young and elderly populations. This non-invasive method could be helpful in measuring internal skin changes for the comprehensive evaluation of skin aging, complementing external assessment methods or devices.
