Science
Mechanism of Action
When ingested, PHGG supports the gut microbiome, leading to improved skin hydration, elasticity, and barrier function via the gut-skin axis. Topically, it creates a protective film or gel matrix on the skin, enhancing moisture retention and lubrication.

Dusting Analysis
Hydrolyzed Guar is typically used for its textural properties or as a dietary fiber, not as a direct 'active' ingredient for skin benefits in topical formulations. Therefore, it is not commonly dusted.
