Science
Mechanism of Action
Operating primarily as a humectant, Polydextrose actively maintains the stratum corneum's hydration levels. Concurrently, it functions as a bulking agent, optimizing cosmetic density, while also improving formulation texture, stability, and facilitating the solubilization of challenging active ingredients like salicylic acid. It further contributes as a rheology modifier, imparting thickening effects.
