BARLEY SH-POLYPEPTIDE-3.

Valuable / SKIN CONDITIONING

A high-precision, plant-derived Keratinocyte Growth Factor (KGF) engineered in barley to stimulate cellular renewal. It serves as a sophisticated bio-identical signal that reinforces the skin’s structural integrity and accelerates epidermal repair.

Science

This polypeptide functions by specifically binding to the FGFR2b receptors located on keratinocytes. This targeted interaction triggers a cascade of cellular proliferation and migration, effectively thickening the epidermal layer and optimizing the skin's natural barrier defense mechanisms.

Key findings

  1. 01 A 90-day VISIA analysis of 45 participants using a serum containing this growth factor reported a 73% reduction in visible wrinkles and a 63% improvement in skin density.
  2. 02 A 30-day efficacy study involving triple growth factors demonstrated significant improvements in pore refinement and a 176% increase in skin hydration levels.
