Science
Mechanism of Action
This ingredient functions through ionic substantivity; its positive charge allows it to anchor to the naturally negative charge of the skin's keratin. Once bound, it forms a breathable, non-occlusive film that prevents transepidermal water loss and neutralizes static, resulting in a refined skin texture and reinforced barrier integrity.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Concentrations as low as 0.1% have demonstrated significant reductions in wrinkle depth and surface roughness over an 8-week period.
- 02 At 0.5%, the ingredient facilitates deeper epidermal penetration, stimulating macrophage activity and collagen synthesis to accelerate wound healing.
- 03 Studies involving sensitive skin subjects confirmed that a 0.5% to 2.0% range significantly improves water retention and barrier function without inducing redness.
Transparency
Dusting Analysis
Because this ingredient is effective at very low concentrations (0.1%), many brands include it at 'label claim' levels (below 0.05%) where it serves no functional purpose for skin barrier repair or wrinkle reduction.
