Science
Mechanism of Action
It binds specifically to PDGFR-alpha and PDGFR-beta cell surface receptors, initiating a signaling cascade that recruits and activates fibroblasts. This process stimulates the synthesis of essential extracellular matrix proteins, including collagen and glycosaminoglycans, while simultaneously regulating MMP2 and MMP9 activity to prevent the enzymatic degradation of the skin's support structure.
Research
Clinical Evidence
High confidence0.1%
Key findings
- 01 Induces a 240% increase in endothelial cell proliferation and a 170% boost in migration at concentrations as low as 0.5-10 ng/mL.
- 02 Clinical trials utilizing 0.1% to 1.0% concentrations demonstrated significant reductions in wrinkle depth and measurable improvements in dermal thickness and elasticity.
Transparency
Dusting Analysis
Due to its nature as a high-potency growth factor, this ingredient is biologically active at nanogram levels (0.5-10 ng/mL). While it may appear at the bottom of an INCI list, concentrations as low as 0.000001% are clinically sufficient to induce fibroblast chemotaxis and proliferation.
The Formula
Formulation
Stability
Highly thermolabile; must be incorporated during the cooling phase below 40°C. It is susceptible to denaturation by proteolytic enzymes and extreme pH shifts.
Synergies
- Hyaluronic acid
- Other barley-derived growth factors (EGF)
- Non-acidic humectants
Conflicts
- Proteolytic enzymes (Papain, Bromelain)
- Strong Alpha Hydroxy Acids (pH < 4.0)
- Strong Oxidants
- High temperatures (>40°C)
Safety
Safety Profile
Barley-derived recombinant proteins are considered safer than E. coli-derived versions as they are free from endotoxin contamination and are bio-identical to human proteins.
