![]() ![]() In the 23 years since this publication, through numerous public health information streams, awareness of the risks associated with UV exposure has increased dramatically. Studies investigating sunscreen application to the face with emphasis on identifying commonly missed areas have very rarely been performed, however, one study in 1994 suggested inferior application to the medial canthal area in a study of 50 participants. Importantly, it has been demonstrated that even when the frequency of application and quantity applied are appropriate, the application technique in terms of coverage, is often inadequate. Use of sunscreens for sun protection requires two conditions to be met: i) adequate quantities of the substance to be applied with appropriate frequency of reapplication, and ii) effective coverage of all sun exposed areas. ![]() Therefore, the importance of adequately protecting this vulnerable area is clear, and the use of sunscreen formulations has been widely promoted. It has been postulated that the high prevalence of non-melanoma skin cancer on the eyelids is due to the skin being the thinnest on the body and hence specifically vulnerable to damage from prolonged ultraviolet (UV) light exposure, a well-established risk factor for BCCs and for squamous cell carcinomas. Within the eyelid area, the medial canthus, a region where the medial corner of the upper and lower eyelids meet, has been shown to be not only a particularly common site for BCC, but is also associated with poor prognosis. Specifically within England, 33610 eyelid BCCs were recorded in the 11 years between 20.

Slominski, University of Alabama at Birmingham, UNITED STATES (2017) UV imaging reveals facial areas that are prone to skin cancer are disproportionately missed during sunscreen application. These data reveal that a public health announcement-type intervention could be effective at improving coverage of high risk areas of the face, however high risk areas are likely to remain unprotected therefore other mechanisms of sun protection should be widely promoted such as UV blocking sunglasses.Ĭitation: Pratt H, Hassanin K, Troughton LD, Czanner G, Zheng Y, McCormick AG, et al. Provision of health information caused a significant improvement in coverage to eyelid areas in general however, the medial canthal area was still frequently missed. Analyses revealed eyelid and periorbital regions to be disproportionately missed during routine sunscreen application (median 14% missed in eyelid region vs 7% in rest of face, p<0.01). missed during sunscreen application, and analysed for 5% significance. Images were scored using a custom automated image analysis process designed to identify areas of high UV reflectance, i.e. To investigate this, 57 participants were imaged with a UV sensitive camera before and after sunscreen application: first visit minimal pre-instruction, second visit provided with a public health information statement. Here we sought to determine if specific areas of the face are missed during routine sunscreen application, and whether provision of public health information is sufficient to improve coverage. However, protection can only be achieved through effective application, and areas that are routinely missed are likely at increased risk of UV damage. Application of sunscreen is a widely used mechanism for protecting skin from the harmful effects of UV light. ![]()
