Science
Mechanism of Action
As a high molecular weight humectant and film-former, it captures environmental moisture into the stratum corneum while physically obstructing trans-epidermal water loss (TEWL). Beyond hydration, its fermented glucose and rhamnose structure interacts with keratinocytes to potentially soothe the skin and support a healthy microbiome environment.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Clinical HRIPT testing across a 0.5-5% range confirmed the ingredient is non-sensitizing and non-irritating, even for reactive skin types.
- 02 Studies at 1-3% concentrations demonstrate significant reduction in TEWL through non-occlusive film formation, providing both immediate and sustained hydration.
Transparency
Dusting Analysis
While effective as a texture enhancer at lower levels, therapeutic hydration and barrier protection require concentrations of at least 1%. Formulations using it below 0.5% are likely leveraging it for marketing claims rather than clinical skin benefits.
The Formula
Formulation
Stability
Exhibits excellent thermal stability and resilience against pH fluctuations; non-ionic nature ensures compatibility with electrolytes.
Synergies
