Science
Mechanism of Action
It acts as a chemical penetration enhancer by increasing the entropy of the stratum corneum's lipid bilayers, temporarily reducing the skin's diffusional resistance to allow bioactives to pass more freely. Additionally, it provides biological soothing by stabilizing cell membranes and downregulating inflammatory mediators such as IL-6 and prostaglandins.

Key findings
- 01 Kraemer WJ, et al. (2004) - Demonstrated that topical blends containing this ingredient significantly improved physical function and reduced discomfort in inflammatory joint conditions.
- 02 US Patent 8,394,759 B2 - Established its role as a chemical penetration enhancer (CPE) that disrupts organized lipid packing to facilitate ingredient delivery.
Transparency
Dusting Analysis
Because it functions as a penetration enhancer at very low levels (0.3%), brands often include it at 'label claim' percentages while marketing much stronger anti-inflammatory or joint-health benefits that typically require concentrations exceeding 5.6%.
