Lip Sunscreen and Lip Cancer Prevention: A Bibliometric Analysis of Research Trends

Squamous cell carcinoma of the lower lip is the most frequent malignant neoplasm affecting the oral region and is strongly associated with chronic ultraviolet radiation exposure. Although the use of sunscreens is widely recognized as an effective strategy for skin cancer prevention, lip‐specific photoprotection remains underexplored in the scientific literature, accounting for only 1.86% of the publications in the analyzed corpus ( n = 536). This bibliometric study assessed the global scientific production on lip sunscreen and lip cancer prevention, focusing on publication trends, key contributors, collaborative structures, citation patterns, and thematic development. Publications indexed in the Web of Science and Scopus databases were analyzed using bibliometric indicators and performance metrics. A total of 536 documents were identified, revealing a gradual increase in research output over time, predominantly concentrated in dermatology and oncology journals. Thematic analysis showed that lip sunscreen is frequently addressed within broader discussions on actinic cheilitis, oral potentially malignant disorders, and ultraviolet radiation exposure, rather than as an independent research focus. Overall, the findings highlight a fragmented and weakly consolidated research field, underscoring the need for more targeted investigations to strengthen evidence‐based strategies for lip cancer prevention.
