Science
Mechanism of Action
Oleosomes are structured as seed organelles containing a triacylglycerol core encased in a phospholipid monolayer and specialized oleosin proteins. Upon skin contact, these reservoirs act as a time-release system, gradually breaking down to deliver stored fatty acids and Vitamin E over several hours. Unlike traditional surfactants, they provide steric stabilization to formulations without stripping the skin's native lipid matrix.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 In vivo testing at 3.0% concentration demonstrated an 18.1% increase in stratum corneum thickness and a significant moisture retention increase of 147.7 µg/cm² over 28 days.
- 02 Formulations utilizing 4.0-10.0% have shown a 20-30% increase in SPF efficiency through improved film uniformity and stabilized UV filter release.

Dusting Analysis
While oleosomes contribute to emulsion stability at lower levels, the clinically validated benefits for barrier thickening and measurable hydration require a minimum concentration of 3.0%.
The Formula
Formulation
Stability
Highly stable across a wide pH range but sensitive to thermal processing; temperatures must remain below 60°C (140°F) to prevent structural collapse. It is resilient in the presence of high ethanol and electrolyte concentrations.
Synergies
- UV filters (SPF boosting)
- Vitamin E
- Ethanol-based formulations
Conflicts
- High-shear processing
- Strong cationic surfactants
- Extreme heat (>60°C)
