Science
Mechanism of Action
It functions by organizing oil-in-water emulsions into lamellar liquid crystal structures. These crystalline networks mimic the natural lipid bilayer of the human stratum corneum, which significantly reduces transepidermal water loss (TEWL) and facilitates a controlled-release delivery system for co-formulated actives.

Key findings
- 01 In a 20-subject clinical evaluation at a 2% concentration, skin hydration increased by 48.6% within one hour of application. Follow-up data at 24 hours showed sustained moisture levels 34.2% above baseline, with significant reductions in visible desquamation and surface roughness over a 4-week period.

Dusting Analysis
Because this ingredient acts as a primary structural emulsifier, it is rarely 'dusted' at negligible levels; however, concentrations below 1.5% may fail to generate the lamellar structures required for its clinical barrier-repair benefits.
