BARLEY SH-OLIGOPEPTIDE-1.

Valuable / SKIN CONDITIONING

A pioneering plant-based recombinant signal peptide that functions as a bio-identical match to human Epidermal Growth Factor (EGF). Produced through green biotechnology in barley seeds, it serves as a high-precision messenger to accelerate skin renewal and structural protein synthesis.

cell-communicating ingredient skin conditioning collagen stimulant

Science

By binding directly to Epidermal Growth Factor Receptors (EGFR) on fibroblasts and keratinocytes, it triggers the MAPK/ERK signaling pathway. This molecular communication stimulates cellular migration and the up-regulation of collagen, elastin, and hyaluronic acid production within the extracellular matrix.

Key findings

  1. 01 Clinical evaluation of barley-derived EGF demonstrated measurable improvements in pore size, dyschromia, and fine line depth within 30 days.
  2. 02 Regulatory assessments indicate 2 ppm (0.0002%) significantly increases skin elasticity and moisture retention while strengthening the barrier function.

Due to its extreme potency and high raw material cost, many 'EGF' products include this ingredient at levels far below the 2 ppm threshold required for physiological signaling.


The Formula

Solubility
Water
Optimal pH 5 – 8
0 7 14

Stability

Thermolabile and acid-sensitive; the peptide structure denatures at temperatures exceeding 40°C or in low pH environments. It requires precise buffering, often using Tromethamine, to maintain biological activity.

Synergies

  • Hyaluronic acid
  • Glycerin
  • Neutral-pH peptides

Conflicts

  • L-Ascorbic Acid
  • Alpha Hydroxy Acids (AHA)
  • Beta Hydroxy Acids (BHA)
  • Strong oxidizers

Sensitization risk Low

While generally safe, its mitogenic (cell-proliferating) nature suggests those with a history of skin cancer or active psoriasis should consult a professional before use.
