BACKGROUND: In recent decades, our understanding of the pathogenesis and pathophysiology of skin photoaging has improved considerably, thereby enhancing preventive and management strategies. The bibliometric analysis demonstrates the chronological trends of publications, highlighting the most influential studies related to skin photoaging. OBJECTIVE: This study aims to identify and analyze the top 100 most-cited articles related to skin photoaging to offer bibliometric information. METHODS: The Web of Science database was searched to obtain publications on skin photoaging. Information from the top 100 most-cited articles was extracted and analyzed using Microsoft Excel 2019 and VOSviewer (version 1.6.18). RESULTS: The top 100 most-cited articles on skin photoaging received a total of 23 925 citations and an average of 239 citations per article. The top most-cited article received 1019 citations and 30.88 citations per article. The publication year ranged from 1995 to 2010, with a peak period of top publications between 2001 and 2005. The Journal of Investigative Dermatology and the Journal of the American Academy of Dermatology published the largest number of top-cited articles. The articles originated from nine different countries, with The United States as the highest contributor. Fisher GJ was the most productive first author from the University of Michigan in the United States and published a total of three articles. A total of 62 keywords were included and grouped into three clusters: 'matrix metalloproteinase', 'collagen' and 'radiation'. The article types include only reviews and original articles. Prevention and treatment-related studies were the most common research focus, followed by pathogenesis, pathophysiology, clinical features and screening methods. CONCLUSION: This bibliometric analysis on skin photoaging demonstrated a major upward trend in the prevention and treatment of skin photoaging, which provides a foundation for future research.
