Silverfree™ (Palmitoyl Dipeptide-52)

Palmitoyl Dipeptide-52

A peptide that defends the pigment you still make — it does not reverse grey.

About This Ingredient

Grey follicles accumulate hydrogen peroxide as their catalase and repair enzymes decline with age — the central, measured lesion of greying (Wood, FASEB J 2009).

The mechanism: Silverfree supports the follicle's oxidative-defence environment around the pigment machinery that is still active.

What it does not do: it does not reverse established grey. No topical cosmetic has been shown to regenerate the depleted melanocyte stem-cell pool — the closest in-class peptide showed no improvement in 78.6% of patients over six months (Melo, Skin Appendage Disord 2023). We state this plainly.

Key Benefits

Pigment Defence

Supports the oxidative-defence environment of follicles that still produce pigment. It does not reverse established grey — and we say so.
Reservoir Protection

Antioxidant support around the pigment machinery still at work — defending what the follicle makes, not restoring what is lost.
Lasting Effect

Not a rinse‑out dye. Acts on follicle biology for results that accumulate and persist with use.
Melanogenesis Reactivated

Stimulates expression of genes that produce melanin, restoring pigment where it was lost.
