Ltd.10.26689/dh.v3i3.12365ArticleDevelopment, Classification, Application, and Research Progress of Modern Skin Photoaging Assessment Toolshttps://artdesignp.com/journal/DH/3/3/10.26689/dh.v3i3.12365YangRuini,YangZhi2025332025-10-17Skin photoaging, a degenerative process caused by ultraviolet radiation, plays a pivotal role in clinical diagnosis and anti-aging research. This paper systematically reviews the evolution of skin photoaging assessment tools, tracing their development from traditional clinical scoring systems to modern imaging technologies, biomarker detection, and AI-assisted analysis. It provides detailed categorization, application scenarios, and comparative evaluations of these methodologies. The study reveals that single-assessment tools have inherent limitations, while multimodal integrated evaluation has emerged as the prevailing approach. Future efforts should focus on integrating molecular biology and AI technologies to establish a more precise photoaging assessment framework.
