The incidence of both melanoma and non-melanoma skin cancers (NMSC) is increasing worldwide and these tumours have become an important health issue. Topical and systemic photoprotection are the cornerstone to decrease the incidence of these tumours. The aim of this study was to collect information about the knowledge of patients with a history of NMSC or melanoma regarding systemic photoprotection. This study was based on a multicentre survey. Standardized, self-administered questionnaires were collected from September 2019 to December 2019 in NMSC and melanoma units, as well as the general dermatology outpatient clinic for the control group. A total of 375 patients were enrolled in two Italian centres. The level of knowledge regarding systemic photoprotection was relatively scarce and was greater in: female patients; patients with normal weight and lighter hair, eye color and skin phototype; patients with a higher educational level; patients with non-cancerous skin conditions; and those who used sunscreens more frequently. A very low level of knowledge of systemic photoprotection was identified among skin cancer patients.
