Repair2

  • Repairing all three skin matrix components may restore function without replacing cells

    Where this hypothesis actsThroughout the mapped altered dermis, including its papillary and reticular layers

    What is proposedRestore the collagen network to predefined structural limits

    With whatNot stated in the record

    HowSequential correction of damaged collagen while retaining existing cells; annual assessment and at most one additional matrix correction course per year

    Possible resultExpected restoration of tissue strength supporting joint recovery of skin functions

  • Selective collagen repair plus core changes can sustain youthful skin without deeper fat repair

    Where this hypothesis actsPapillary and reticular dermal regions predicted to reach calibrated fatigue failure within twenty years

    What is proposedRestore collagen molecular integrity to the matched youthful range in selected regions

    With whatNot stated in the record

    HowSelect regions by independently calibrated cumulative fatigue thresholds and freeze selection before testing; the collagen repair technique is not stated

    Possible resultExpected preservation of youthful repeated-load and mature-wound performance without hypodermal restoration

Remodelling2

  • Restoring collagen, elastin networks and basement membranes may restore youthful skin function

    Where this hypothesis actsDermis throughout the selected area of aged skin

    What is proposedRestore the organized structure of collagen fibers

    With whatNot stated in the record

    HowOne initial cell-free course without special maintenance treatment; the restoration technology remains to be developed and tested

    Possible resultExpected restoration of skin strength, contributing to sustained recovery of all skin functions for ten years

  • Stored tension in replacement collagen makes continuous repair paths harmful

    Where this hypothesis actsNewly deposited collagen paths retaining incompatible local prestress in aged human explants with hypodermis

    What is proposedSelectively interrupt newly deposited tensile paths with the greatest release recoil

    With whatPhysical or surgical intervention

    HowUse collagen labeling and multiphoton-guided microablation to sever selected paths while matching total turnover and directional bulk stiffness

    Possible resultPossible reduction in attachment strain and increased cycles to reopening despite reduced collagen connectivity
