Science
Mechanism of Action
This copolymer acts as a multi-functional delivery system. The Ceramide NS component integrates into the stratum corneum to mimic and replenish the skin's natural lipid bilayer. Simultaneously, the PEG-8 and Succinic Acid framework creates a cohesive, film-forming network that locks in hydration and provides a structured delivery vehicle for lipophilic ceramides in aqueous environments.
Research
Clinical Evidence
High confidence0.2%
Key findings
- 01 Clinical assessments demonstrate that Ceramide NS at a 0.2% concentration significantly reinforces the skin's lipid barrier, leading to a measurable reduction in transepidermal water loss (TEWL).
- 02 Usage data confirms that even at trace concentrations (0.001%), the ingredient contributes to the structural integrity and arrangement of the skin's lipid bilayers.

Dusting Analysis
Because ceramides are expensive and effective at low levels, many brands include them at 'label claim' concentrations (below 0.01%) that offer minimal barrier repair. For precision results in barrier restoration, look for concentrations closer to the 0.2% pure ceramide equivalent.
The Formula
Formulation
Stability
The copolymer structure makes this ingredient highly water-dispersible, solving the common formulation challenge of incorporating pure, insoluble ceramides into serums. It remains stable in standard skincare pH ranges.
Synergies
- Cholesterol
- Fatty Acids
- Glycerin
- Hyaluronic Acid
Conflicts
- Strong oxidizing agents
- High alkalinity (pH > 8.0) which can trigger hydrolysis
Safety
Safety Profile
While the 2020 CIR Expert Panel limits pure Ceramide NS to 0.2%, the copolymer solution itself is often utilized at 1-5% within a formula to achieve those active levels.
