Science
Mechanism of Action
It integrates into the lipid lamellae to repair the skin's permeability barrier. Additionally, it inhibits tyrosinase and melanin synthesis, modulates inflammation via the NF-κB pathway, and exhibits antimicrobial action against P. acnes.

Clinical Evidence
High confidence0.05%
Key findings
- 01 Potently inhibits melanin synthesis and tyrosinase activity for skin brightening, effective at concentrations significantly lower than kojic acid (0.001%-0.1%).
- 02 Improves barrier function, reduces inflammation, and decreases microcomedones (up to 25% reduction observed in related studies at 0.1%-2% in complex formulations).

The Formula
Formulation
Stability
Highly lipophilic, requiring emulsification or dissolution in oils/glycols. It is stable across a broad pH range (3.5-9.0), with optimal performance in skin-neutral to slightly acidic conditions.
Synergies
- Other lipids for enhanced penetration
Conflicts
- Strong oxidizing agents
- Highly acidic formulations (pH <3.0)
Safety
Safety Profile
Reviewed by CIR as part of ceramides and sphingosines, considered safe and non-sensitizing at typical topical use levels. Concentrations exceeding 5% are not typically used in cosmetics due to potential cellular toxicity.
