This research explores the sunscreen and photoprotection habits of individuals with photosensitivity conditions, specifically comparing those with porphyria to those with non-porphyric photosensitivity. The study highlights the challenges patients face in selecting effective sunscreens, given the wide variety of products and the limited guidance on their efficacy, especially concerning protection against visible light. Findings indicate that protection efficacy is the primary factor influencing sunscreen choice, particularly for porphyria patients, who often require sunscreens that protect against visible light. The authors reveal that many patients struggle with sunscreen selection, reporting issues with product suitability and expressing a need for improved guidance and accessibility to tailored sunscreens. This study underscores that sunscreens are a crucial supplement to broader photoprotection strategies, but they are not a standalone solution for photosensitive individuals.

This academic article, published in the British Journal of Dermatology, investigates the safety of Far-UVC light (200-230 nm) for individuals with photosensitivity disorders, a group often experiencing adverse skin reactions to various light wavelengths. Far-UVC is known for its germicidal properties and is considered a promising tool for reducing infectious disease transmission. The study, conducted at a photodiagnostic unit in Scotland, involved phototesting 83 patients, including those with diagnosed photosensitivity, using a filtered krypton chloride lamp that emits Far-UVC at 222 nm. Importantly, no visible skin changes were observed in any participant, even at the maximum exposure aligned with international safety guidelines. These findings suggest that Far-UVC, when properly filtered and within recommended exposure limits, is unlikely to harm photosensitive skin, supporting its broader use as a disinfection method in public spaces.

This academic article, published in Photochemical & Photobiological Sciences, presents research on the effectiveness of eye protection for patients undergoing oral psoralen photochemotherapy (PUVA), a treatment for skin conditions. The study investigates various types of eyewear, including sunglasses and safety glasses, assessing their ability to block ultraviolet (UV) radiation following psoralen ingestion. While laboratory measurements showed many lenses effectively block UV, real-world simulation experiments revealed that factors beyond the lens, such as frame design and fit, significantly impact overall protection. The findings highlight the importance of choosing eyewear with close-fitting, wrap-around styles and darker frames to minimise UV exposure from various angles, particularly during the period of heightened photosensitivity after taking psoralen.

This is an AI generated summary of the publication COVID-19's Impact on Scottish UV Phototherapy from the Photobiology Unit, NHS Tayside and the University of Dundee.

This letter to the editor, published in Clinical and Experimental Dermatology, examines the long-term effects of the COVID-19 pandemic on ultraviolet (UV) phototherapy services in Scotland. Ewan Eadie uses data from Photonet, a Scottish UV phototherapy network, to demonstrate a 26% reduction in patients treated compared to pre-pandemic levels. He attributes this decrease to a complex interplay of factors including staff shortages, reduced clinic hours, longer waiting lists, and changes in patient preferences and treatment options. Despite this decline, the author highlights the cost-effectiveness of UV phototherapy and advocates for service improvements to increase access. The letter concludes by suggesting that many UK dermatology services likely face similar challenges.

This research article details a pilot study evaluating a home-use kit for daylight photodynamic therapy (dPDT) to treat actinic keratoses (AKs). The study assessed the kit's usability and practicality, finding it convenient for patients but highlighting the need for comprehensive training and support. While patient willingness to reuse the kit was high, efficacy varied, suggesting a need for improved patient selection and support. The kit's design incorporates sustainability principles, utilising natural sunlight and recyclable materials to minimise environmental impact and hospital visits. Future research will focus on cost-effectiveness, safety, and broader implementation.
