The Diversity Gap: Microbiome Drift After 60

For women over 60, the skin's ecosystem is in a state of flux. As the skin ages, changes in pH, lipid production, and barrier integrity lead to a phenomenon known as "Microbiome Drift." The diverse, balanced microbial community that once protected the skin has become depleted, with a significant loss of beneficial strains. This creates a "Diversity Gap," where the skin is more susceptible to colonization by opportunistic species that drive chronic low-grade inflammation.

PDRN: The Biological Symbiote for Ecosystem Revival

The Finch Marine Protocol's Repair Phase utilizes the regenerative power of PDRN to restore the skin's microbial balance. PDRN is not just a repair molecule; it is a potent optimizer of the dermal-microbiome axis. When applied to mature skin, PDRN enhances keratinocyte health and lipid synthesis, creating a robust physical barrier that serves as the foundation for a healthy microbiome.

Restoring the Biological Ecosystem and Resilience

The ultimate goal of microbial revival is the restoration of the skin's "Biological Ecosystem." This is not a temporary fix achieved with topical probiotics; it is a genuine, biological restoration of balance that comes from within. By closing the diversity gap and reinforcing the dermal-microbiome axis, the Finch Marine Protocol allows the skin to reclaim its natural state of resilience.
