Skin aging doesn’t happen cell by cell. It spreads.
When a skin cell becomes senescent, often called a “zombie cell,” it stops functioning normally but doesn’t die. Instead, it releases inflammatory factors and tissue-breaking enzymes that push neighboring healthy cells into that same dysfunctional state. One senescent cell becomes several. Several becomes a cascade.
That’s how a small, localized issue turns into visible aging across the skin: inflammation builds, repair slows, and the surrounding tissue ages faster than it should.
The OS-01 Peptide™ works by penetrating the top layers of skin to help healthy, younger cells multiply. It strengthens the skin barrier and reactivates collagen production, restoring skin health so it looks and behaves like younger skin.
“By preventing senescent cells from releasing pro-aging factors, we can prevent healthy cells from becoming zombies, containing the spread of senescence and slowing down skin aging.”
