Scientists Detect Hidden Skin Damage Before It Becomes Visible Skin aging and tissue damage are often identified only after collagen fibers become thinner, fragmented, or lose their structural integrity. However, these visible changes may occur much later than previously thought. A new study published in ACS Nano suggests that collagen begins to lose its molecular organization long before conventional imaging can detect any structural abnormalities. The findings provide new insights into the earliest stages of skin aging and tissue deterioration. Researchers from Hiroshima University and collaborating institutions used advanced light-based imaging and spectroscopy techniques to examine human skin collagen at the molecular level. They discovered that collagen can lose its highly organized three-dimensional structure, known as supramolecular chirality, even when: Collagen fibers still appear normal under conventional imaging. The total amount of collagen remains largely unchanged. The tissue appears structurally intact. This suggests that molecular deterioration may p
