Geographic and population disparities in cutaneous melanoma in the United States: state-level trends and national population-level analyses.
BMC public health · 2026
BACKGROUND: Over recent decades, cutaneous melanoma (CM) incidence in the United States (US) has increased but now appears to be plateauing, whereas mortality has declined. However, much less is known about how CM incidence and mortality vary between states, or about how differences between states in incidence relate to lifestyle factors, ambient UV exposure, and prevention or health care… Read on PubMed →

Protective Effects of Astragalin Against Acute Ultraviolet B-Induced Photodamage in HaCaT Cells and Mouse Skin.
International journal of molecular sciences · 2026
Astragalin (AST), a natural flavonoid found in various plants, possesses antioxidant and anti-inflammatory properties. However, its protective efficacy against ultraviolet B (UVB)-induced cutaneous damage remains unclear. This study investigated the photoprotective effects of AST against UVB-induced photodamage using HaCaT keratinocytes and Kunming mice. In vitro, AST mitigated UVB-induced… Read on PubMed →

The as-synthesized samples were characterized using ultraviolet-visible spectroscopy, field-emission scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction analysis techniques. The optical band gap of… Read on PubMed →
A global score for skin environmental exposure: integrating UV radiation, heat, and pollution via fuzzy analytic hierarchy process.
International journal of biometeorology · 2026
Environmental stressors such as ultraviolet radiation (UVR), air pollutants, and thermal stress interact synergistically to accelerate skin damage, yet most available indicators still assess these factors in isolation. The Skin Environmental Exposure Score (SEES) is a new and innovative fuzzy logic-based tool that integrates UVR, heat, ozone, and particulate matter into a single 0-1000 score… Read on PubMed →
Photoprotective Potential of a Yeast/Rice Fermentation Filtrate and Sialic Acid in Mitigating UVA-Induced Oxidative Stress and Mitochondrial Dysfunction in Skin Fibroblasts.
Molecules (Basel, Switzerland) · 2026
Ultraviolet A (UVA) radiation induces oxidative stress and mitochondrial dysfunction in dermal fibroblasts, contributing to photodamage and skin aging. This study investigated the protective effects of Yeast/rice fermentation filtrate (RFF) and sialic acid (SA), both individually and in combination, against UVA-induced damage in human dermal fibroblasts.

International journal of molecular sciences · 2026
Ultraviolet (UV) irradiation induces complex skin damage, including hyperpigmentation, oxidative stress, and alterations in proteins related to keratinocyte differentiation and epidermal barrier-associated status. This study investigated the multifunctional protective effects of Padina arborescens ethanolic extract (PAEE) against skin damage in melanocytes, keratinocytes, and zebrafish. In… Read on PubMed →
Closing the Gap in Photoprotection: Implications for Skin of Colour in Australia.
The Australasian journal of dermatology · 2026
Long wave UVA1 is a critical driver of hyperpigmentation and skin aging in skin of colour. In combination with visible light, it shares a synergistic relationship in amplifying oxidative damage and hyperpigmentation in skin of colour. Disorders of hyperpigmentation affect a large proportion of Australians and have significant psychosocial burden. Photoprotection remains the mainstay of treatment… Read on PubMed →
The cutaneous microbiome as a dynamic photoprotective interface against solar radiation.
Photochemical & photobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology · 2026
This review reframes cutaneous photoprotection as a host–microbe system and synthesizes evidence, largely from experimental model systems and human observational studies, that resident skin microbes sense, transform, and defend against solar ultraviolet stress. We introduce the “host-protective UV-resistome” defined as the subset of microbial genes and pathways that confer photoprotection to the… Read on PubMed →

Sunscreen and vitamin D: Part I.
Clinics in dermatology · 2026
It is so ubiquitous in our medicine drawers, as a supplement and as a therapy, that we hardly give a thought to the process of its discovery. It feels as if we have always had vitamin D. Our early ancestors were thought to have had darkly pigmented skin and to have migrated out of Africa some 70,000 to 60,000 years ago. With their migration, they evolved to have lighter skin, thereby losing some… Read on PubMed →
Sunscreen and Vitamin D. Part II: Sunscreen, SPF and Impact on Vitamin D.
Clinics in dermatology · 2026
Sunscreens were available in ancient societies, such as Egypt, Greece, Arabia, and Japan, often to help keep the skin lighter and more fashionable. With the promotion of a tan as a sign of a leisurely, privileged lifestyle came the discovery of the harmful effects of sunlight on the skin. These include skin cancer, discovered by Unna and experimentally confirmed by Findlay, which paved the way for… Read on PubMed →
TiO2 nanoparticle-embedded starch-tannin biocomposites with efficient UV-shielding and ROS elimination as Pickering emulsifier for bio-safe sunscreen.
International journal of biological macromolecules · 2026
Inorganic nanoparticles with excellent anti-ultraviolet ability such as titanium dioxide (TiO2) are extensively utilized in sunscreens to protect against UV-induced skin photodamage and carcinogenesis. However, conventional TiO2 nanoparticles exhibit inherent photocatalytic activity that generates harmful reactive oxygen species (ROS), which limits their applications as sunscreen. In this work, we… Read on PubMed →
