Science
Mechanism of Action
By integrating into the stratum corneum's intercellular lipids, this ingredient effectively 'plugs' gaps in the barrier. This action prevents transepidermal water loss (TEWL), providing a substantive protective film and restoring skin flexibility.

Clinical Evidence
High confidence3%
Key findings
- 01 Demonstrates significant improvement in skin barrier function and hydration, effectively reducing TEWL and aiding in the repair of compromised skin like cracked lips/heels.
- 02 Serves as a benchmark for biomimetic lipid replacement, integrating into the stratum corneum to restore flexibility, particularly in extremely dry or aged skin.

The Formula
Formulation
Stability
Highly stable due to acetylation, which prevents oxidation and rancidity compared to non-acetylated sterols. It is a thick, viscous paste/liquid at room temperature requiring melting into the oil phase (60°C–80°C).
Conflicts
- Strong oxidizing agents
- Strongly acidic environments (pH < 3.0) may cause slow hydrolysis
Safety
Safety Profile
Reviewed by the CIR Expert Panel under 'Alkyl Esters', considered non-sensitizing and non-irritating at typical use levels. FDA and SCCS recognize these esters as safe for cosmetic applications.
