Science
Mechanism of Action
It functions as a moisture-binding monosaccharide that enhances the Skin's Natural Moisturizing Factor (NMF). By regulating 'hydric flow' within the epidermis, it stimulates the synthesis of essential lipids and proteins required for healthy keratinocyte differentiation and barrier integrity.
Research
Clinical Evidence
High confidence1.5%
Key findings
- 01 Low-dose 0.5% applications in cleansers significantly mitigate surfactant harshness while providing sustained hydration.
- 02 Concentrations between 1% and 5% in leave-on formulas demonstrate measurable moisture retention lasting up to 72 hours.
Transparency
Dusting Analysis
Because it is active at levels as low as 0.5% in rinse-off products, brands often include it at negligible amounts (below 0.1%) to claim 'long-term hydration' without providing the concentration necessary to actually counter surfactant irritation or reach the 72-hour efficacy window.
The Formula
Formulation
Stability
A highly stable pyranose ring structure that resists thermal and chemical degradation. It is exceptionally water-soluble (approx. 674 g/L).
Synergies
- Xylitol
- Xylitylglucoside
- Glycerin
Safety
Safety Profile
Generally regarded as safe; while specific 2018 surveys noted 0.17% in bubble baths, its chemical group is safely used up to 2.8% in leave-on skincare.
