Science
Mechanism of Action
This amphiphilic molecule features a glyceryl core that attracts water and long-chain fatty acids that seal it in. With a high molecular weight of approximately 1,200 g/mol, it stays on the skin's surface to form a breathable, non-penetrating occlusive shield that prevents transepidermal water loss.
Research
Clinical Evidence
High confidence20%
Key findings
- 01 Demonstrated an impressive water-binding capacity of 170%–200% of its own weight, outperforming many traditional emollients in hydration longevity.
- 02 Proven to significantly enhance skin firmness and reduce TEWL (transepidermal water loss) when used at or above this threshold.
- 03 Confirmed as non-irritating and non-sensitizing in HRIPT testing, even at high inclusion rates in leave-on lip formulations.
Transparency
Dusting Analysis
While often used as a texture enhancer at lower levels, therapeutic barrier benefits for firmness and water loss reduction require concentrations of 10% or higher. Formulations using it only for label claims at sub-1% levels are effectively 'dusting'.
The Formula
Formulation
Stability
Highly thermally stable with a melting point near skin temperature (35-39°C), facilitating a smooth application. It is resistant to oxidation and heat sterilization.
Synergies
- Humectants like Glycerin
- Ceramides
- Plant oils
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
Its large molecular size prevents systemic absorption, making it an exceptionally safe topical choice for compromised barriers.
