Science
Mechanism of Action
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.

Clinical Evidence
High confidence0.0002%
Key findings
- 01 Clinical evaluation of barley-derived EGF demonstrated measurable improvements in pore size, dyschromia, and fine line depth within 30 days.
- 02 Regulatory assessments indicate 2 ppm (0.0002%) significantly increases skin elasticity and moisture retention while strengthening the barrier function.

Dusting Analysis
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
Formulation
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
Safety
Safety Profile
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.
