Science
Mechanism of Action
This extract operates through a multi-pathway approach: it upregulates the expression of filaggrin, involucrin, and loricrin to strengthen the cornified envelope while stimulating aquaporin-3 for internal moisture transport. Its high fucoxanthin content provides potent antioxidant defense, while its ability to inhibit MMP-1 enzymes helps preserve the dermal collagen matrix against environmental degradation.

Clinical Evidence
High confidence1%
Key findings
- 01 In vitro comparative testing demonstrated that at 0.1%, this diatom extract outperforms nicotinamide in the expression of filaggrin and aquaporin-3.
- 02 Clinical application between 0.25% and 2.5% significantly lowered transepidermal water loss (TEWL) by enhancing tight junction protein synthesis.
Transparency
Dusting Analysis
Because this is a complex botanical extract with a long INCI name, it is frequently used at 'claim levels' (below 0.1%). However, clinical data suggests a minimum threshold of 0.25% is required to achieve measurable barrier repair benefits.
The Formula
Formulation
Stability
Highly stable at physiological temperatures (up to 37°C); however, it is sensitive to extreme acidity which can cause protein precipitation.
Synergies
- Ceramides
