Science
Mechanism of Action
By leveraging a dual-natured structure, it integrates exogenous lipids directly into the stratum corneum, effectively sealing gaps between corneocytes. This reinforcement minimizes transepidermal water loss (TEWL) and stabilizes the skin's protective mantle through the delivery of carotenoid-rich Tucumã fatty acids.
Research
Clinical Evidence
High confidence8%
Key findings
- 01 Clinical evaluations demonstrate that an 8% concentration provides peak skin barrier reinforcement and superior lipid particle stability.
- 02 Human Repeat-Insult Patch Tests (HRIPT) confirm a total lack of sensitization or irritation at standard usage levels up to 5%.
Transparency
Dusting Analysis
To achieve tangible barrier repair and oxidative stability benefits, this ingredient should be present at 1% or higher; concentrations below this are typically used for surface-level emulsification rather than clinical efficacy.
The Formula
Formulation
Stability
Exhibits significantly higher oxidative resistance than raw Tucumã oil due to the esterification process; stable in both oil-in-water and water-in-oil emulsions.
Synergies
- Lipid carrier systems
- Carotenoids
- Ceramides
Conflicts
- Highly acidic environments (pH < 3.0)
- Strong oxidizing agents
Safety
Safety Profile
Recent CIR safety updates removed previous 5% restrictions for leave-on products, citing a robust history of non-irritation at higher concentrations.
