Science
Mechanism of Action
This ingredient operates as a dual inhibitor of the serine proteases Plasmin and Urokinase (uPA), preventing the enzymatic breakdown of the skin barrier and Collagen IV. It further promotes cellular cohesion by upregulating Transglutaminase 1 (TGase1) and stimulating Collagen I synthesis, while rebalancing the skin microbiome by favoring beneficial Staphylococcus epidermidis over pro-inflammatory bacteria.
Research
Clinical Evidence

Key findings
- 01 A 28-day clinical study utilizing 1% concentration reported a 16-17% reduction in transepidermal water loss (TEWL) and a significant improvement in stratum corneum integrity (p < 0.02).
- 02 Recent 2024 data indicates that even at 10 ppm (0.001% pure active), the peptide significantly increases collagen density and skin elasticity while reducing wrinkle volume.
Transparency
Dusting Analysis
Because this peptide is physiologically active at extremely low concentrations (10 ppm), it is frequently used at trace levels for marketing claims. However, to achieve the clinically validated 16-17% reduction in TEWL, a 1% concentration of the commercial blend is the established benchmark.
The Formula
Formulation
Stability
The molecule is most stable in acidic environments; commercial solutions are typically maintained at pH 2.6-3.6 to ensure long-term peptide integrity.
