Ultraviolet Radiations Impact on the Skin‐Brain Axis: A Literature Review of our Current Knowledge

Photodermatology, Photoimmunology &Photomedicine, Volume 42, Issue 3, May 2026.
ABSTRACT Background Sunlight is essential for vitamin D synthesis and contributes to mood regulation, but it is also a major risk factor for skin aging and carcinogenesis. While the cutaneous and immune effects of ultraviolet radiation are well documented, its potential impact on brain function remains poorly understood.
