Science
Mechanism of Action
This ingredient functions as a pseudo-18-MEA (18-methyl eicosanoic acid) replacement. Its cationic (positively charged) structure allows it to target and anchor specifically to damaged, negatively charged sites on the skin barrier and hair cuticle. Once bonded, it creates a persistent, moisture-retaining film that mimics the body's natural protective F-layer.
Research
Clinical Evidence
High confidence1%
Key findings
- 01 In vivo trials at a 1.0% concentration demonstrated a 6.4% reduction in skin extensibility, signaling a quantifiable increase in firmness and moisture retention.
- 02 At a 0.3% concentration, the ingredient successfully restored the hydrophobic F-layer on damaged surfaces, significantly lowering the frictional coefficient for smoother texture.

Dusting Analysis
Because this ingredient is often supplied in a diluted solution (20-25% active), brands frequently list it at low percentages that look impressive on a label but fall below the 1.0% threshold required for measurable skin-firming benefits.
The Formula
Formulation
Stability
Highly stable within the standard physiological pH range; typically formulated as an aqueous solution with glycerin.
Synergies
- Glycerin
- Ceramides
- Non-ionic emulsifiers
Conflicts
- Strong anionic surfactants
- High-electrolyte environments (high salt concentrations)
Safety
Safety Profile
Safety is dependent on a molecular weight of 3,500 Daltons or less to ensure the hydrolyzed protein does not trigger hypersensitivity.
