Science
Mechanism of Action
It functions as a biomimetic agent by organizing into lamellar liquid crystalline structures that closely replicate the human skin's lipid bilayer. This 'second skin' formation reinforces the stratum corneum, creating a breathable yet protective film that prevents transepidermal water loss while stabilizing the oil and water phases of a formula.

Key findings
- 01 Clinical testing of a 5.0% concentration demonstrated a 23% increase in skin hydration levels maintained for 8 hours post-application.
- 02 Research indicates that concentrations between 3.0% and 5.0% are required to successfully form the stable liquid crystal structures necessary for barrier enhancement.
Transparency
Dusting Analysis
To achieve the liquid-crystal barrier-mimicking effect, a concentration of at least 3% is typically required; inclusion at levels below 1% suggests it is being used merely for label appeal rather than structural or physiological benefit.
The Formula
Formulation
Stability
Exhibits robust stability across a pH range of 3.0 to 10.0, though skin-optimal formulas should stay within 4.0-7.0. It is notably resilient in the presence of high salt or electrolyte concentrations.
Synergies
- Oil-phase lipids
- Humectants
Conflicts
- High concentrations of cationic surfactants
Safety
Safety Profile
The CIR Expert Panel confirmed its safety in 2020. Due to its high molecular weight, it remains on the surface of the skin without risk of systemic absorption.
