Natural Agents for Preventing Skin Damage Induced by Visible Light: A Systematic Review of Preclinical and Clinical Evidence

Photodermatology, Photoimmunology &Photomedicine, Volume 42, Issue 5, September 2026.
ABSTRACT Background/Purpose Visible light (VL), and particularly high‐energy visible light (HEVL), reaching Earth's surface has emerged as a relevant contributor to skin damage. VL has been implicated in oxidative stress, inflammation, pigmentation disorders, and photoaging, especially in individuals with darker skin phototypes.

Myopic shift in female mice after ovariectomy

Scientific Reports
Myopia is a global public health concern, with a higher prevalence in women than that in male. As the relationship between sex hormone and myopia remains unclear, we aimed to reveal the relationship between sex hormone and myopia by removing the ovaries ...

Histone Acetylation Modifications Affect Tissue-Dependent Expression of Poplar Homologs of C4 Photosynthetic Enzyme Genes

Frontiers in Plant Science, 2017
Histone modifications play important roles in regulating the expression of C4 photosynthetic genes. Given that all enzymes required for the C4 photosynthesis pathway are present in C3 plants, it has been hypothesized that this expression regulatory ...

Spectroscopic Investigation of the In Vivo Light‐Dependent Photodynamics of the Marine Diatom Phaeodactylum tricornutum

ChemPhysChem, Volume 27, Issue 13, 14 July 2026.
µm fourier transform infrared (FTIR) image, 442 nm Raman of the Si–O of the silica‐based frustule at 472 cm−1, and UV–vis of Phaeodactylum tricornutum cells. Marine diatoms are responsible for fixing CO2 into organic carbon and contribute to the regulation of global climate.

Measuring Daylight: A Review of Dosimetry in Daylight Photodynamic Therapy

Pharmaceuticals, 2019
Successful daylight photodynamic therapy (DPDT) relies on the interaction of light, photosensitisers and oxygen. Therefore, the ‘dose’ of light that a patient receives during treatment is a clinically relevant quantity, with a minimum dose ...

Conditioned Medium from Irradiated Keratinocytes as a Tool for Investigating Communication within the Melano‐epidermal Unit

Current Protocols, Volume 6, Issue 7, July 2026.
Abstract Keratinocytes and melanocytes form the melano‐epidermal unit, whose communication is essential for maintaining the integrity, homeostasis, and functionality of the skin. This interaction is mediated by keratinocytes’ release of various soluble factors, which modulate key processes in melanocytes such as melanogenesis, proliferation, adhesion ...

Photoperiod‐Regulated Thermal Tolerance of the Non‐Diapausing Insect Ceratitis capitata (Diptera: Tephritidae)

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 725-735, July 2026.
Developmental photoperiodic exposure (photoacclimation) from egg to adult emergence alters thermal tolerance in Ceratitis capitata. Flies reared under contrasting photoperiods (0:24, 8:16, 14:10, and 24:0 L:D) showed significant shifts in both CTmin and CTmax, whereas adult‐only photoacclimation affected CTmax but not CTmin.

Beyond Tint: Active Ingredient Strategies for Post‐Inflammatory Hyperpigmentation due to Visible Light in Skin of Color

Photodermatology, Photoimmunology &Photomedicine, Volume 42, Issue 4, July 2026.
ABSTRACT Background Post‐inflammatory hyperpigmentation (PIH) is among the most burdensome sequelae of inflammatory dermatoses in skin of color (SOC), and reduction of visible pigmentation represents the primary clinical outcome of interest. Tinted sunscreens containing iron oxides and/or pigmentary titanium dioxide are currently the best‐evidenced ...
