Science
Mechanism of Action
By grafting hydrophilic PEG-8 chains onto the fatty acid backbone of Tucumã oil, this ingredient functions as a biomimetic emollient. It reinforces the skin's lipid barrier while simultaneously stimulating the internal synthesis of glycosaminoglycans like hyaluronic acid, ensuring both moisture retention and structural hydration.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 In vitro testing demonstrated a 27% increase in endogenous hyaluronic acid synthesis within skin cells.
- 02 Clinical evaluation of nanoemulsions showed a 19.28% increase in stratum corneum hydration levels after a single application.
- 03 Proven to reduce transepidermal water loss (TEWL) by forming a non-comedogenic, silky protective film.
Transparency
Dusting Analysis
Because it is an expensive Amazonian derivative, it is frequently used at 'claim' levels (below 0.5%) to market the presence of Tucumã oil. However, its significant hydration and hyaluronic-boosting benefits only manifest at concentrations of 1% or higher.
