Science
Mechanism of Action
This 'pseudo-ceramide' functions by reinforcing the intercellular cement of the stratum corneum. It leverages alpha-linolenic acid to reorganize lipid bilayers, which not only physically repairs the skin barrier but also optimizes neuro-sensory communication to dampen irritation signals at the surface.
Research
Clinical Evidence
High confidence1%
Key findings
- 01 Concentrations of 1.0% demonstrated significant reduction in skin reactivity and measurable decreases in transepidermal water loss (TEWL).
- 02 Usage levels between 0.5% and 2.0% are clinically validated for the restoration of the lipid barrier in atopic and chronically dry skin conditions.
Transparency
Dusting Analysis
Because this ingredient is expensive and functional at low levels, brands often include it at 'claim' levels (below 0.1%) where it cannot effectively restructure the lipid barrier. A minimum of 0.5% is required for therapeutic barrier repair.
The Formula
Formulation
Stability
Exhibits superior thermal stability up to 85°C and offers greater oxidative resistance than raw vegetable oils due to its stabilized ester form.
Synergies
- Cholesterol
- Phytosphingosine
- Niacinamide
Conflicts
- Strong oxidizing agents
- Formulations with pH below 3.0
Safety
