Homeodynamic Rejuvenation: an adaptive framework for resetting skin aging

Area of Science:

• Dermatology
• Integrative Biology
• Skin Physiology

Background:

• Skin aging involves molecular damage and reduced ability to adapt to environmental stress.
• Current aging models don't fully capture the dynamic nature of skin adaptation.
• Homeodynamic Rejuvenation offers a new framework for understanding and addressing skin aging.

Purpose of the Study:

• Introduce Homeodynamic Rejuvenation as a novel concept for skin vitality.
• Define homeodynamic plasticity as the skin's capacity to maintain function under stress.
• Integrate homeodynamics with exposome biology to target cellular repair and recovery.

Main Methods:

• Focus on five core biological processes: intracellular quality control, regenerative competence, metabolic resilience, cellular integrity, and structural integrity.
• Link these processes to functional decline and skin aging, including dermatoporosis.
• Propose evaluation through dynamic perturbation-recovery kinetics to measure stress response and recovery.

Main Results:

• Homeodynamic plasticity underpins the skin's ability to sustain function under stress.
• Failure in core biological processes leads to progressive functional decline and aging.
• Dynamic perturbation-recovery kinetics can quantify skin resilience.

Conclusions:

• Homeodynamic Rejuvenation aims to restore functional competence and biological vitality.
• This framework targets the reactivation of cellular systems for stress sensing, repair, and recovery.
• It provides a structured, translational approach to quantifying and restoring skin resilience.
