Matrix restoration targets skin rejuvenation

Can ageing skin recover durable, youthful function when its own cells regain the structural support they have lost? This proposed mechanism tests that question in a predefined area of middle-aged human skin. A cell-free treatment would rebuild collagen, the strength-bearing skin protein; the elastin-fibrillin network, which lets tissue stretch and recoil; and basement membranes, thin layers that anchor cells. The prediction is that resident aged cells could then sustain several functions for a decade. A rival hypothesis requires tiny cellular grafts at key connective-tissue sites. Testing the difference requires verifying all three structures, tracking resident cell lineages, measuring sensation and sweating, and defining combined recovery in advance.
