sh-Polypeptide-3

sh-Polypeptide-3 is a biotechnologically produced (fermentation-derived) polypeptide included in advanced regenerative serums. As a recombinant protein fragment it interacts with cell-surface receptors to support keratinocyte and fibroblast activity — promoting renewal, density, and repair processes that slow with age. Clinical specifics are largely manufacturer data, but the ingredient class (bio-identical signal proteins) represents the state of the art in biotech skincare, popularised by Korean "glass skin" and post-procedure lines. It suits resilient-skin seekers, mature skin, and post-laser recovery. Use in clean, well-preserved formulas; efficacy depends heavily on the surrounding delivery system.
