Scientists detect hidden skin damage before it becomes visible

ScienceDaily reports that researchers have identified an early warning sign of skin damage that appears before any visible deterioration. Using advanced light-based techniques, the team discovered that collagen's molecular organization—specifically what scientists call its molecular handedness—can break down even while the skin still looks intact and contains the same amount of collagen. This suggests skin may begin aging at a much deeper molecular level long before conventional imaging can detect a problem.
