Science
Mechanism of Action
Functioning as a physical abrasive, Polyhydroxybutyrate mechanically assists in dislodging dirt and dead skin cells from the skin's surface, contributing to pore unclogging and textural refinement. Concurrently, it acts as a skin conditioning agent, supporting the maintenance of skin in optimal condition.

Stability
Polyhydroxybutyrate demonstrates poor resistance to both acidic and basic environments, indicating potential instability at extreme pH values. Furthermore, it exhibits limited stability at elevated temperatures, undergoing thermal degradation during melting processes that can negatively impact its physical and mechanical characteristics.
Safety
Safety Profile
Although Polyhydroxybutyrate is recognized as biocompatible and non-toxic in applications such as medical devices and bioplastics, specific safety assessments by cosmetic regulatory bodies like CIR, SCCS, or FDA for its direct incorporation into skincare formulations are currently unavailable.
