BackgroundEnvironmental ultraviolet radiation has deleterious effects on humans, including sunburn and immune perturbations. These immune changes are involved in skin carcinogenesis.ObjectivesTo determine whether nicotinamide riboside and/or pterostilbene administered systemically inhibits inflammatory and immune effects of exposure to mid‐range ultraviolet radiation.MethodsTo examine UVB radiation‐induced inflammatory effects, mice were fed standard chow/water, 0.04% pterostilbene in chow and 0.2% nicotinamide riboside in drinking water, diet with nicotinamide riboside alone, or diet with pterostilbene alone. After 4 weeks, mice were exposed to UVB radiation (3500 J/m2), and 24‐/48‐h ear swelling was assessed. We also asked if each agent or the combination inhibits UVB radiation suppression of contact hypersensitivity in two models. Mice were fed standard diet/water or chow containing 0.08% pterostilbene, water with 0.4% nicotinamide riboside, or both for 4 weeks. Low‐dose: Half the mice in each group were exposed on the depilated dorsum to UVB radiation (1700 J/m2) daily for 4 days, whereas half were mock‐irradiated. Mice were immunized on the exposed dorsum to dinitrofluorobenzene 4 h after the last irradiation, challenged 7 days later on the ears with dinitrofluorobenzene, and 24‐h ear swelling assessed. High dose: Mice were treated similarly except that a single dose of 10,000 J/m2 of radiation was administered and immunization was performed on the unirradiated shaved abdomen 3 days later.ResultsNicotinamide riboside and pterostilbene together inhibited UVB‐induced skin swelling more than either alone. Pterostilbene alone and both given together could inhibit UVB‐induced immune suppression in both the low‐dose and high‐dose models while nicotinamide riboside alone was more effective in the low‐dose model than the high‐dose model.ConclusionNicotinamide riboside and pterostilbene have protective effects against UVB radiation‐induced tissue swelling and immune suppression.

BackgroundVitiligo is characterized by depigmented patches resulting from loss of melanocytes. Phototherapy has emerged as a prominent treatment option for vitiligo, utilizing various light modalities to induce disease stability and repigmentation.Aims and MethodsThis narrative review aims to explore the clinical applications and molecular mechanisms of phototherapy in vitiligo.Results and DiscussionThe review evaluates existing literature on phototherapy for vitiligo, analyzing studies on hospital‐based and home‐based phototherapy, as well as outcomes related to stabilization and repigmentation. Narrowband ultra‐violet B, that is, NBUVB remains the most commonly employed, studied and effective phototherapy modality for vitiligo. Special attention is given to assessing different types of lamps, dosimetry, published guidelines, and the utilization of targeted phototherapy modalities. Additionally, the integration of phototherapy with other treatment modalities, including its use as a depigmenting therapy in generalized/universal vitiligo, is discussed. Screening for anti‐nuclear antibodies and tailoring approaches for non‐photo‐adapters are also examined.ConclusionIn conclusion, this review provides a comprehensive overview of phototherapy for vitiligo treatment. It underscores the evolving landscape of phototherapy and offers insights into optimizing therapeutic outcomes and addressing the challenges ahead. By integrating clinical evidence with molecular understanding, phototherapy emerges as a valuable therapeutic option for managing vitiligo, with potential for further advancements in the field.

BackgroundOrgan transplant recipients (OTR) are more likely to develop skin cancer than the general population. One of the main components of the exposome that triggers the development of skin tumours is solar ultraviolet (UV) radiation. To reduce the incidence of harmful consequences of sun exposure, sun protection education is needed for patients taking long‐term immunosuppressive drugs.MethodsIn a previous study, we assessed the sun‐safe behaviour of 221 OTR using a questionnaire before and after transplantation and personally educated the patients about proper sun protection. After the education, there were no further reminder presentations. Presently, the sun protection and sun seeking habits of the available 176 of these patients were questioned to assess the long‐term effect of the previous sun protection education.ResultsTwo‐four years after the education, more patients wore hats and protected their skin with long‐sleeved clothing than before the education. In terms of sun seeking habits, both occupational and recreational sun exposure decreased significantly. Significantly fewer people went on holiday after transplantation, but those who went on holiday spent significantly less time in the sun.ConclusionThe long‐term positive effects of education can be seen both in the patients' sun protection and in their sun seeking habits. However, the long‐term goal is to maintain these results and thereby reduce the likelihood of skin tumours and consequently the associated tumour death.
