Photoprotection encompasses topical, physical, behavioral, educational, environmental, and regulatory measures aimed at reducing exposure to ultraviolet radiation, the primary modifiable environmental risk factor for cutaneous melanoma.

To evaluate the effectiveness of photoprotection interventions, compared with no intervention, usual care, or less intensive strategies, for preventing cutaneous melanoma and modifying intermediate outcomes related to ultraviolet radiation.
A systematic review with narrative synthesis and no meta-analysis was conducted following PRISMA 2020. PubMed/MEDLINE, Embase, Scopus, Web of Science, Cochrane Library, and LILACS were searched up to December 30, 2025, in English or Spanish. Randomized clinical trials, quasi-experimental studies, cohort studies, and case-control studies assessing photoprotection interventions or exposures were included.
The main synthesis included 15 studies. Regular sunscreen use provided the most direct signal of lower melanoma incidence. Sun-protective clothing, school-based, family, occupational, and community programs, and digital tools showed effects on melanocytic nevi, sunburn, ultraviolet exposure, and adherence to photoprotective behaviors. Indoor tanning was associated with a higher risk of melanoma. Heterogeneity in designs, populations, and outcomes precluded meta-analysis.
The findings support photoprotection as an integrated and sustained strategy. Studies with objective measures of exposure, real-world adherence to photoprotective measures, and longer follow-up are needed.
