Science
Mechanism of Action
As a cationic polymer, POLYQUATERNIUM-58 carries a positive charge, enabling it to ionically bond with the naturally negatively charged surfaces of hair and skin. On the skin, it establishes a thin, invisible film that works to smooth the surface texture, filling in minor irregularities to impart a soft, silky sensation. This protective film functions as a barrier, effectively minimizing water loss and thereby enhancing skin hydration and strengthening the skin's inherent barrier function. It can also aid in reducing static electricity on the skin.

Verdict
Despite a described mechanism indicating benefits for skin hydration and barrier support, the absence of specific clinical studies on skin efficacy, irritancy, and comedogenicity data for POLYQUATERNIUM-58 means further research is required for a conclusive verdict on its skin-specific performance and comprehensive safety profile.
