Introduction: occupational and recreational activities are the most important causes of exposure to solar radiation, the cumulative effect of which could lead to the development of skin cancer.Objective: determine dermatological injuries associated with sun protection among outdoor workers in the Provincial Municipality of Huánuco in 2023.Methods: an analytical observational study of a census nature was carried out. The instrument used was validated through five expert evaluations, obtaining a Kappa index of 0,94. The reliability of the instrument was evaluated using the α-Cronbach coefficient of 0,68 and Kuder-Richardson 20 of 0,69. The sample included 300 subjects. The techniques used were behavioral observation, interviews and surveys. The statistical analysis consisted of the use of Chi2.Results: a statistically significant association (p < 0,05) was found between sociodemographic variables, hours of sun exposure, and sun protection practices. However, there was no association between dermatological injuries and sun protection practices in workers exposed and not exposed to solar radiation (p > 0,05).Conclusion: dermatological injuries were observed due to solar radiation exposure in both groups, including those engaged in outdoor activities and those with minimal sun exposure
