Science
Mechanism of Action
It operates via an amphiphilic structure where the caprylic portion integrates into the stratum corneum's lipid bilayers to prevent transepidermal water loss (TEWL), while the PCA moiety acts as a humectant, drawing moisture into the intracellular spaces to maintain turgor and elasticity.

Key findings
- 01 Studies on PCA derivatives indicate a significant increase in skin hydration levels and barrier recovery speed when applied in leave-on lipid-based formulations.
Transparency
Dusting Analysis
Because it functions as both a texture enhancer and an active barrier repair agent, it is rarely 'dusted' for marketing; however, concentrations below 0.5% may not provide meaningful physiological barrier support.
The Formula
